Hey Guys!

I'm currently enrolled in a Cisco CCENT course at my school. I'm having major problems with subnetting and learning it.

A:Subnetting on the fly...


Re your private addresses (192.168.1.x): This is a class C address range (Private network) that is not visible on the internet.

A subnet of means you can have 256 addresses (but you can't really use 0 and 255). You can actually use a different subnet if you want (assuming you needed that many addresses. For example, would give you 256 x 256 (65536) addresses, all for your own personal use (again, as they can't be used on the public Internet).

If you wanted to limit the number of addresses you might use which would split your network into 4 subnets. This can get complex, so you might want to look at Understanding TCP/IP addressing and subnetting basics or IPv4 - Wikipedia, the free encyclopedia if you really want to understand IPv4.

Regarding you public address:

Typically an ISP will use a subnet of This means that you get only one address, the public address they give you. This is how they segment and allocate their finite IP address range. It also help with security from their perspective, as it helps prevent spoofing.

Hello everyone, first time poster. I am currently working on some practice subnetting problems and need some assistance. I've filled out most of the answers myself, but I still need some help on a few of them.

The following questions are the ones I was able to answer:

Host IP Address - - six bits have been borrowed to create the required subnets.

Class? - C
Default subnet mask? -
Subnet mask? -
Subnets created? - 64
Usable hosts per subnet? - 2
Network Address? -
Broadcast Address? -

These are the ones I am having trouble with:

The following addresses are either Network, Host, or Broadcast - answer appropriately.


How am I supposed to figure these out? Is there an easy way of knowing? Thanks in advance for any assistance.

A:Need help with subnetting!

The Network address is the lowest IP in the subnet; the Broadcast is the highest; all others can be assigned to hosts.

having a bit of a problem and was hoping someone could clear this up please.
now i thought if you subnetted your network of lets say
123.111.321.0/24 and subnetted it to 123.111.321.0/27, now we have eight subnets with 31 hosts each i believe and what i thought that this was like having seperate networks as in and ie cant talk to eachother without a router. but it seems that people are telling me that
123.111.321.1/27 can still talk to 123.111.321.60/27 over a switch, even though these are different subnetts. is this right as this is comming from a pretty reputable source.

Thankyou for you help


Without knowing how your network is set up, concievably the switch could be a layer 3 switch providing the routing between subnets or there can be a router on the subnets to route between them.

At the very basic level, if someone mis-configured their subnet mask, then there can be some be some overlap between subnets.

You are recruted as an network technician in the company University.

Your first job is to configure all the hosts in a network. You have to assign fixed ip addresses to

have to test your network on a simulation tool: Packet Tracer 4.1.

The company made already an analysis of the network. The results of this analysis you’ll find it

So you start your job with the following data.

Hello, I am a current college student enrolled in a TCP/IP online course. Now that I am on my last week of class I realize I would have best learned this probably in an actual classroom. I have failed the last 3 quizzes for this course because my book does not seem to explain things to me in a fashion I can understand it. On the last quiz my teacher had 23 subnetting questions on something that was not taught in the book and I could not find online. I emailed him about my tests and how I have not grasped this and asked him to point me in the right direction but he told me I can retake these quizzes this week but I have to figure it out myself... I have my dad and brother helping me trying to understand this but still cannot get it.

Just a quick run down on the subnet mask. For the longest... I've read ton's of material even doing a virtual training course by CBT Nuggets now, but I just don't understand why for example:
Why is the mask always 255? What does the 255 actually mean/determine? I know that = a mask of because 255 = 11111111 and 3x8=24 but I just don't understand why a mask is 255.

I saw in another post a good link by JohnWill http://www.ralphb.net/IPSubnet/ it looks very good, but still I don't know what 255 determines.
The idea I get, hopefully this makes sense is that because of the 0 I can have upto 254 clients on that one netmask.

Hi Guys,

I'm new to networking. One of my assessments requires me to create a network and subnet it, depending on the amount of hosts on each LAN. We get given a random block of ip addresses to work with.

What i was wondering is: say i get a class b network to work with (, and one of the LAN's need 60 hosts on it. Am I able to use the subnet mask, because its total hosts is 62. Or is that subnet only allowed in class c addresses? If not, which subnet mask do I use, because the subnet mask range for class b addresses are 510-65534 hosts, and that is too many hosts for what I need.

I just need it cleared up for me,

My friend and I are having a friendly debate that seems to have centered on a rather semantic issue. The point in question is whether an IP address 192.168.x.x/16 is referred to as a full class B or a supernetted class C. The following is the most recent stances we have taken via emails:

We know that any IP address beginning with 0-126 is a class A, 127-191 is class B, and 192-224 is class C. It doesn't matter if you subnet it or supernet it. By definition, the first bits of the first octet of the ip address will always designate it as a class a, b, or c...
You can't call an ip address starting with 192 a class B. I am confident that 192.168.x.x/16 should be referred to as a supernetted class C network. Just like 10.x.x.x/26 is a subnetted class A. Are you saying you would refer to 10.x.x.x/26 as a class C network?

Absolutely, a network of would be a FULL class C. We are dealing in semantics, you are hung up on the classful way of defining the IP address and I am using the term "class C" to define the size of the network... my way happens to be the more common way now that clasfull networking is no longer used (except in books).

Can anyone clear this up for me? Should be referred to as a full class B or a supernetted class C?

I have a network of 192.9.200.x with a subnet of I want to break out the network for more hosts. I was thinking maybe 8 subnets with 254 hosts per subnet. My question is, can I start moving the network to the new subnets while leaving the other equipment on the current subnet mask without losing communication? Or is it an all or nothing where once I start I have to move every device and cannot do it in increments?

A:Subnetting question

You're not being very clear so let me clarify what i think you are asking.
Firstly it appears you want to subnet (which means split an existing network) your 192.9.200.x network into a further 8 subnets with 254 hosts on each. If this is the case then no you can't. At the moment you can only have 254 hosts on your existing subnet anyway so splitting it further will mean less hosts per subnet. If you were to subnet this network into 8 subnets you would need to borrow 3 bits from the host ID (4th octect) leaving you with only 5 bits for hosts. 2 to the power of 5 gives 32-2= 30 hosts per subnet. So you can subnet it to 8 subnets but you can only have 30 hosts per subnet.

Subnetting is about splitting a network into smaller "sub" networks. If for example you set the subnet mask to then your network ID is now 192.9.x.x and you can SUBNET this further.

I dont see your point though...What are you trying to achieve? If all you want to do is create 8 different subnets with 254 hosts per subnet just assign 8 class C IP address ranges using a subnet mask of IE your ranges would be:
192.9.200.x mask gives you 254 hosts
192.168.1.x mask gives you 254 hosts
192.168.2.x mask gives you 254 hosts
192.168.3.x mask gives you 254 hosts and so on...

If you want to truly subnet a network you would have a root network like 172.16.x.x (Class B) with subnet mask Then you can subnet t... Read more

I'm doing a worksheet in my CCNA class.

and asks:

Is this a valid IP host address? Why or why not?

Just having a little trouble with this question (I haven't gotten around to finish reading the chapter we're in the middle of just yet).

Thanks for the help.

A:Question about Subnetting (I think...) is a Class B network host address. The only thing that might make this an invalid address is if it is a subnet address or a subnet broadcast address. The subnet mask shows that 8 bits were borrowed to create subnets. This results in a subnet table that would look like this:
SN#0: Address: hosts: - b'cast:
SN#1: Address: hosts: - b'cast:

So, lies within the valid host address range of SN#0, so it is valid. If you are using classful addressing in your router, however, the CCNA curriculum states that no SN#0 addresses can be used. Routers CAN use classless addressing, so this address really would work. It depends if the question is asked based on classfull addressing being used or not.

Hello everyone,

I'm on subnetting.net trying to figure out subnetting through the amount of host and subnets required. I am mostly getting wrong answers by just a bit or two and I'm not seeing what I'm doing wrong. Some help would be greatly appreciated.

Example 1-

"What subnet mask would you use for the 172.0.0 network, such that you can get 170 subnets and 170 host per subnet?"

My work, 2048 1024 512 256 | 128 64 32 16 8 4 2 1

255.255. (class B)

Borrow from 256, so that's 9 bits. So convert 8 of those to 255 and the last one to 128 right?

So Which isn't the right answer. Apparently the answer is
Example 2-

"What subnet mask would you use for the network, such that you can get 1670 subnets and 30 hosts per subnet?"

Class B again. So 255.255 from the start.

2048 1024 512 256 | 128 64 32 16 8 4 2 1

Borrow from 2048, That's 12 bits. Convert 8 of those to 255 and the next 4 from 128-16. Which is 240.

So But it says the answer is

Hey there, im currently studying for MCSE, and im just making sure that i've understood the below article correctly:

"If a TCP/IP host with the address sends a packet to the address, the host first performs a bitwise AND operation beteween the local address and the locally configured subnet mask. Because ANDing and is 172.20.00. The host then performs a bitwise AND operation between destination address and the same subnet mask which results in binary equivilant of TCP/IP compares the values and if they're the same, it concludes the destination is on local subnet. If the two values differ, the host determines that the destination is remote"

In this case, the destination address is a remote one correct? Because it is a class B address and class B addresses first 2 octects are network ID and not hosts.

If the destination was on a class B address, then the destination would be local correct? Thanks very much in advance!

I need some guidance on subnetting a wireless network.

Currently, we have a T1, wired network using DHCP. We want to keep the wired network wired. We would like to add a wireless access point for our in-store customers to use. We want to keep the wireless users from being able to browse our internal network. I am thinking of subnetting....

The firewall we now have (a SOHO 6) has a builtin DHCP that we use. If I get a wireless AP, how do I keep the DHCP numbers from conflicting with one another? I mean, both the AP and the FW will have to have the same external IP, DNS, etc., so won't they conflict somehow?

Hi all ,

By starting with a given IP address and prefix (subnet mask ) assigned by the net administrator ,you can begin creating your network documentation

This is calculating and assigning address without VLSM .

He needs 4 subnetworks with 481,69,23,2 hosts so 9 host bits at a minimum to cover the subnet with 481 hosts and therefore you run out of addressing as you will only end up with 2 subnetworks each with 510 as calculated as follows .

The way I would interpret this is as follows : gives 2 subnets /23 and /22
the first 22 bits Network section
the 23rd bit the bit borrowed for subnetting the subnet
the last 9 bits host bits which gives 2^9 –2 hosts
ie 510 hosts per each of two subnets

Therefore , gives the following 2 subnets

Subnet 0
Subnet 1

You are borrowing 1 bit from the host bits as opposed to 7 bits which the following book interpretation does .
The Book interprets it as follows

In the book he starts with /23

the first 16 bits are the Network section
the next 7 bits are the bits borrowed for subnetting ie 2^7 subnets =128 subnets
The last 9 bits are host bits which gives 2^9 –2 hosts ie 510 hosts per each of 128 subnets
subnet 0
subnet 1

well the assignment is to develop an abstract type for handling characters. Only handling 26 capital letters. I have this need help with CharSet.cc


class CharSet
bool Contents [26];

CharSet(); //constructor initializes set to be empty

void Add(char Value); //add character to set corresponding bool set to
void Remove(char Value); //Removes char corresponding set to true

void Union(CharSet ASet); //Union the set passed a parameter into set

void Intersect(CharSet ASet); //Intersects set passed a parameter
contains results of intersection
bool Member(char Value) const;
}//end class CharSet

Also have testSet.h which is my test

#include "Charset.h"
#include <iostream>
using namespace std;
void printSet(CharSet ASet)
for (char c = 'A' ; c <= 'Z' ; c++)
if (ASet.Member (c))
cout << c;
}; //end if
}; //end for
cout << endl;
}; //end printSet
int main()
CharSet Set1;
CharSet Set2;
CharSet Set3;


cout << "Expect BC" << endl;
cout << "Expect ABCD" << endl;
cout << "Expect BD" << endl;
printSet(Set2);... Read more

I am currently studying C# and received a practice assignment for this:

Write a program for a teacher.The program should have an array that can hold the
test scores for 30 students.The program can randomly assign grades from 1 to 100 .
Determine the average score for the class.

This is what I came up with:

using System;
class Aprog{
public static void Main(){
int[] grade= new int[31];
int ctr;
System.Random rnd=new System.Random();
Console.WriteLine("Student{0}, Grade:{1}",ctr,grade[ctr]);
if(grade[ctr]>0 && grade[ctr]<50){
else if(grade[ctr]>50 && grade[ctr]<60){
else if(grade[ctr]>60 && grade[ctr]<70){
else if(grade[ctr]>70 && grade[ctr]<80){

It works but some how it does not feel right or kind off sloppy. Does anyone know of a better way to create this application?

Hi gfxrelay,

Never refrain from using methods to make the coding more readable :

[SIZE=2]using System;
class Aprog{
public static void Main(){
int[] grade= new int[31];
int ctr;
System.Random rnd=new System.Random();
Console.WriteLine("Student{0}, Grade:{1}",ctr,grade[ctr]);

private static string getLevel(int grade) {
if (grade >= 80) return "A";
if (grade >= 70) return "B";
if (grade >= 60) return "C";
if (grade >= 50) return "D";
return "F";

You are part of a software development team. I am your project leader. Our assignment is to develop a virtual calculator for the University. We have decided to develop the calculator using C++. I have given you the task to develop another math library called (arrays.h). In this library you are to develop the following functions:

add, subtract, multiply
These functions will take an array of numbers, the array size and two integer numbers as their parameters. The two integer numbers represent locations in the array. It will add, substract, or multiply the numbers at the two specified locations in the array return the result.
It should be able to handle arrays that are doubles, ints, and longs.
Return values should be of the same type as the array.
This functions will take an array of numbers, the array size and two integer numbers as its parameters. The two integer numbers represent locations in the array. It will divide the first number located at the position designated by the first integer by the second number located at the position designated by the second integer parameter. It will return the result.
It should be able to handle arrays that are doubles, ints, and longs.
If the value of the second number is zero, this function will display an error message to the screen and return -999 .
Return values should be of the same type as the array.

You are not going to find what you need here. Do the research. The fact that you can't even spell it means you have a lot to do.
