Subnet Mask Assignment

Q: Subnet Mask Assignment

I'm going to add another IP Camera.

The manufacturer's search tool shows the new (and exisiting) camera but indicates that my PC is not on the same subnet mask. After a quick "CMD--> ipconfig" search, I see that my wireless PC is on subnet mask while all other devices are on

Keep in mind that I have ATT Uverse with a gateway that serves as a router. All other devices (wired or not) are on If I hard wire the PC to the router, I am assigned a subnet. If I unplug the Ethernet cable, the PC recognizes this lost network connection and goes to wireless where I'm assigned the subnet and therefore not able to connect with my ipcamera's, NAS drive, etc.

While on wireless, Ive tried ipconfig /release and ipconfig /renew, nothing happens (still assigned

I've confirmed in the in the network connections tab that TCP/IPv4 is setup to
-Obtain an IP address automatically
-Obtain DNS server address automatically

I don't know what the problem could be. Im not sure why I'm being assigned a subnet outside of the normal What can I do?

A:Why is my subnet mask

The subnet mask for the WAN (Internet) side is assigned by your ISP. The Subnet mask is used in calcuating how many IP addresses can be allocated. It's only part of the picture. As it is the WAN side, it should not be a worry for you.

For your network, using the class C addresses 192.168.1.xxx, with a subnet mask of means you can have 255 addresses (well, 254 actually, since you can't really use; as that has other meanings).

Translating your internal traffic from LAN to WAN is what NAT is all about.

If you do an ipconfig /all from your computers you will see that your adapters show an address in your DHCP range, with a subnet mask of, assuing you haven't statically assigned an address.

With your DNS servers, that is fine. Many people don't use their ISP assigned DNS. I use Open DNS, many people use google. There are many. Indeed, not using your ISPs DNS servers can result in better performance if the DNS server your using is set up specially to handle DNS lookups and little else.

Hello Have Samy UN40ES6100. Previously, tv used a wired connection. It was ran a short while wifi, maybe 4 yrs ago. Now physically moved to an apt and must use wireless on this tv.

I want to use an alternative DNS server to that of my provider.

The DNS addresses of the alternatives are listed, but not the 'Subnet Mask' which seems to be required in the Network Connections' TCP IPv4 dialogue.

Can I leave this blank or is it mandatory ?

A:Subnet Mask in DNS Settings

There is no Subnet Mask setting in DNS configuration. There is only the IP address for the Primary and Secondary DNS servers.

The Subnet mask setting is for your own IP address if it is statically defined. Typically this would be assigned dynamically by your router or ISP. If a static IP is used the subnet mask is required.

Hi everyone,

I need to pick the brains of several network specialists. If you know TCP/IP like the back of your hand, please read this and see if you can help me.

A machine somewhere doesn't seem to connect to the LAN. It has a subnet mask of

Straight away, I noticed the address was subnetted, so I started working it out and it didn't make sense.

The third octet of the subnet mask concerns me. On the third octet, if you were to borrow 2 bits off the host portion (all bits set to 0) to create subnetworks, you'd end up with a subnet mask of If you were to borrow 3 bits off the host portion, you'd end up with a subnet mask of
So, it looked like a typo to me. They meant to put 224, not 204.
The person who set this up confirmed that this was correct but it doesn't make sense to me. You can't have a bit set to 1 after a bit set to 0 in an octet for a subnet mask, so where does the 224 come from? It should either be 192 or 224.

Am I correct or am I missing something critical here?

A:How do you tell where the subnet mask is located?

What is Subnet Mask?

By Scott Seong
An IP address has two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses (<network><host>). Subnetting further divides the host part of an IP address into a subnet and host address (<network><subnet><host>). It is called a subnet mask because it is used to identify network address of an IP address by perfoming bitwise AND operation on the netmask.

A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address. Subnet Mask is made by setting network bits to all "1"s and setting host bits to all "0"s. Within a given network, two host addresses are reserved for special purpose. The "0" address is assigned a network address and "255" is assigned to a broadcast address, and they cannot be assigned to a host.

Examples of commonly used netmasks for classed networks are 8-bits (Class A), 16-bits (Class B) and 24-bits (Class C), and classless networks are as follows:

Class Address # of Hosts Netmask (Binary) Netmask (Decimal)
CIDR /4 240,435,456 11110000 00000000 00000000 00000000
CIDR /5 134,217,728 11111000 00000000 00000000 00000000
CIDR /6 67,108,864 11111100 00000000 00000000 00000000
CIDR /7 33,554,432 11111110 00000000 00000000 00000000

I have two networks set up in my home .I have all wired computers hooked up to router A that is router / modem combo . All wireless and other wired computers hooked up to router B

I have two subnet mask. Some one was saying if I use same subnet mask on both routers , I would have problems.Should I be using the same subnet mask? What is subnet mask ? When should I use two subnet mask ? I thought every network needs it's own subnet mask? Or data would not know to be sent to router A.

Also router B does not need to know the gateway or DNS of the ISP , all it neesds to know is the IP address of router A.

I read that DHCP should be disabled on router B . I do not know why that is the case.

A:Should two routers use the same subnet mask?

Yes, you need the same MASK - - but there are bigger issues than the mask itself.

Q.a) Also router B does not need to know the gateway or DNS of the ISP , all it needs to know is the IP address of router A.

Q.b) I read that DHCP should be disabled on router B . I do not know why that is the case.Click to expand...

If you wire from A(lan slot) --->(lan slot)B (ie leave the B wan port empty, then you will use B as a switch, not a router - - very effective and 99% of the time, the solution you were after in the first place. If B has Wifi, that is still operational !!.

We disable DHCP in the B router to make Q.a true. Router A's DHCP will control all devices attached to either A or B.

Now to assist in allowing B to be configured while attached this way, it needs an IP address on the same subnet as A and A needs to never allow DHCP to handout B's IP address.

on A, set the DHCP range from 2-100 (that's more than reasonable)
on B set its IP address static to 254 (if A is x.y.z.1 then B is x.y.z.254)
If B has WiFI, then you can modify those settings with the browser
http://x.y.z.254 and enter the user/pwd for router B

btw: if you wire A(lan)--->(wan)B, then B will enable NAT and devices on A will not be able to access devices on B.

..how can i find the subnet mask of a website so i can block ip ranges in my router firewall? can i calculate that from only one ip?

A:Subnet mask of an ip range!

You cant determine that from only 1 address

You would probably have to do a traceroute to the offending IP, and then start the same process to each IP above, until your 2nd to last hop changes IP (meaning different router), then repeat the process to each IP below until a different 2nd to last hop is reached.

Of course that assumes that their network doesn't block ICMP, and also assumes every (or most) IP on that range are up.

I know routers give out out IP addresses ,forward the packets and can block the packets . Well a switch just forward the packets. My questions is how does one router know how to talk to other router? I read that the routing table control this and how it is hooked up . But I'm confused here.

What is subnet mask? Is subnet mask just a way of having other networks? Having two or move routers with same IP address of the connecting computer will lead to major problems ? Only way to have the same IP address on the connecting computers is to use other subnet mask?

A:Trying to understand routers vs switch and subnet mask.

Not all routers are setup to act as a DHCP server to give out IP addresses. And some layer 2 switches have a DHCP server to give out IP addresses.

A switch actually forwards frames not packets. This is a common mistake in terminology which even seasoned network professionals make. It's common enough where when someone talks about packets and switches, its already an implied reference to frames.

A router is a layer 3 device which forwards packets on to another destination when it receives a packet to process. How the router knows how to forward a packet is through its route table. The route table is either self configured through known IP addresses from local interfaces on the router, through manual configuration called static routes in the router's configuration, or through learning of routes with what's called dynamic routing protocols (RIP, OSPF, EIGRP, and BGP).

In the first scenario where the networks are known through the local interfaces, this is what the route table would look like when we have a simple two interface router where Int1 has an IP of and Int2 has an IP of So the router knows that if it receives a packet from a host on the network destined for a host with an IP of on Int1. The router knows that the packet needs to be forwarded to Int2 as it has an interface on the network. The same thing would happen in the reverse direction. But if a packet originating on the 192.168.0.x network ... Read more

When it finally does load, is your CPU running at 100% or close to it? Or does it just take forever to load and then works fine?

You might be getting alot of collisions working with the second subnet, depending on what kind of hardware you're using to load all the network settings and stuff.

I can control font size in the body of email, and other areas, but within small windows of AOL and web sites accessed through AOL again the miniscule fonts, icons etc. I have used browser settings within AOL, and in the display settings of Windows 10 I have changed the resolution to all available and the mask of AOL does not alter, It is so small I cannot read what I type. I am guessing most of the times. I have spoken to AOL and they claim there is no way to alter the size of the mask other than through Browser Settings in AOL Keyword and/or Display settings within 10. I really cant understand how that would be true, I have come to the point that I may leave AOL for another browser, I have Gmail and hotmail available and I do not have that trouble. Any help and/or suggestions would be appreciated.

I know that in every other game in town, there's nothing worse than knowing enough to be dangerous. That's me. I've spent a gazillion hours on the www learning about subnet masks and I think I know enough about bits,bytes,and the like to make a mask for my small network. And that there's only a handfull of possible ones. My network is an ASA firewall, 3 servers, and a couple dozen workstations and devices. It was always a network with a mask. My goal is to split it, and restrict the available ip's. (I have only ever used static ip's. No DCHP. I have always lived that way and like the control of static ip's). - I came up with to with a mask of (half the network will be to and My understanding is that 16 is the network address, 17 the lowest ip available, 30 the highest, and 31 the broadcast ip. So the questions are.. 1.)Am I right with the ip's and the mask? 2.) Is it true that and can not be used for a host, the firewall or other device? 3.) If someone programs a static ip on their laptop of or 40 or any other number with a mask of, what will happen? Can they use the gateway I'm assigning as Are they locked out of browsing the lan?

I thank you in advance for your patience and answers. I'm about to implement and hope I didn't just become an educated meathea... Read more

A:Building a Mask

You are correct on (1) and (2) unless I missed something.

For (3) in theory the computer with the different mask won't be on the same network, but I think that you can't count on no networking being successful.

Hi, how might one mask an IP with a proxy? I'm not sure how this works but seeing as I have a static IP, I though it might safer.

How do you use these prxies?

Is it a program you download and use or/and sign up for at a site? Can you specify what IP to hide behind?

What other ways are there of masking an IP?

Thanks for your time

When sending out a private message using the BCC function in outlook, how can you make it so the recipient's see your email address as "[email protected]" (that's just an e.g.) basically just looking for a way to mask your email address?


A:BCC Mask with Outlook

Hi croboy

Create a new Contact using your e-mail address and key in whatever you wish to be displayed in the Display As: field and the Name: field.
In your message, select the new Contact you just created for the To: field, then add your recipients in the Bcc: field.

This will not actually mask your e-mail address as Outlook will show the e-mail address next to the display name, in the message.
Using this method, you will not reveal any of your Bcc recipients to the other Bcc recipients.
