HAT IS SUBNET MASK - Linksys Community. With the above answer given I can imagine that this does not explain it quite enough. It's also much more complicated and yet also very simple. There are lots of sites that will give more detailed information though, but here is some right now: IP addresses are grouped by something called subnet mask. Every ip address has a corresponding subnet mask. The subnet mask specifies the range of the ip addresses in a group. The subnet mask looks a lot like an ip address.
It is made up of four eight bit numbers separated by periods. These numbers once again range from 0 to 2. A typical subnet mask is 2. There are a couple intresting things about subnet masks.
They don't really behave like you would initially expect them to. The numbers of a subnet mask count ip addresses that are not there. This means higher the numbers of a subnet mask are the less ip addresses belong to it. For example: 2. 55. There are no ip addresses in this range. This is the range of all ip addresses. Lets take one of the most basic subnets the 2.
The first step is to put the subnet into binary. Let go ahead and do that now. If you don't know how to put something into binary read Binary Numbers for more information. So how do we find out how many ip addresses are in this group? Well its rather simple actually. Just count the number of zeros, and then take 2 to the number of zeros power. In this case it would be 2^8 = 2.
How do I set up static routing? • Subnet Mask. NOTE: All Linksys routers are set to Class C subnet.. Network Setup : Router IP . Subnet Mask. Completing the Internet Setup section is all that is required to set up for your specificISP. How do I configure hotComm and a LinkSys router? In your LinkSys router. Almost all Linksys configurations use this subnet mask.*.

Another way to do it is to multiply 2 times itself 7 times. So we have two hundred and fifty six ip addresses in that range! Another thing that is intresting to know. Subnets will always be all ones on one side, and all zeros on the other. I mean that they will always look like 1. Lets take a closer look at what a group of ip addresses looks like. Using the 2. 55. 2.
Subnet Address. 19. Broadcast Address Every group of ip addresses, has a Subnet Address, Broadcast Address, and Gateway. Both the Subnet Address ip address and the Broadcast Address ip address are used to send information to every ip address in the group. The Gateway acts sort of like the group's controller. For instance, let's say that your computer is on the ip address 1. When you send send information to the internet, your computer sends data to the gateway. Then the gateway sends that data on to the internet.
The same thing is true when you get data from the internet. The internet sends data to the gateway, and then the gateway passes that information on to your computer. The gateway can be on any ip address in the range. Usually it is on the second ip address in the range, or the second ip address from the end of the range. The Subnet Address is always on the first ip address in the range, and the Broadcast Address is always on the last one in the range. Okay I'm going to change our subnet from 2.
How to create a subnet at home with Linksys router. This set-up works fine for all my client. Can I use it as a router to create a 10.10.1.x subnet.
Lets say the ip address of our computer is 1. How many ip addresses do we have? Well lets convert the subnet to binary. You should get the following binary subnet.
Okay, we have four zeros. So take 2^4 which equals 1. Alternatively 2*2*2*2 equals 1. We have 1. 6 ip addresses in our range. Well lets draw out our table. We can't draw our ip address table without knowing where the range starts.
This is how you figure that out. We take our subnet and AND it to our ip address converted into binary. Go ahead and conver our ip address into binary.
You should get the following. Now we AND that with our subnet. It is easy to think of ANDing as finding the truth of two numbers. Every 1 is true and every 0 is false. True and true is true! True and false is false.
False and true is false. False and false is false.
Changing the Subnet Mask on a Linksys WRT54G. Changing your subnet mask affects how your router is seen. Click the 'Setup' tab. Click the 'Subnet Mask' field.
So lets line up our subnet and our ip address. So look at the first column. We have a 1 and a 1. The next column is the same thing. The thrid column is a 0 and a 1. Continue doing that for the whole number. Now that we have our result lets take it and convert it back to base 1.
Great! Now that we have our first ip address and we know that we have 1. Subnet Address. 19. Gateway. 19. 2. 1. Our computer! 1. 92. Broadcast Address.
How to create a subnet at home with Linksys router. My home network consists of my ISPs router (Thompson TG5. WIFI and Ethernet LAN connections on the 1. The router's LAN address is 1. This set- up works fine for all my client computers except in one case: I have to connect to a client's VPN, and I am using the generic VPN Windows connection to do that (as per their instruction). The VPN connection fails, and I was told by their security guys that the reason is that my IP address is in the 1. Question 1: Why does it matter that my internal IP address is on the same range as theirs?
Using other VPN clients like CISCO client for other customers whose internal network is in the same range works just fine. Maybe something different with this type of VPN? Question 2: I also have a Linksys WRT5. GS router which I am currently using as a gateway to extend my WIFI range in the office. Can I use it as a router to create a 1. VPN instead? I have tried to switch its Advanced Routing mode to Router (from Gateway), and tried to configure Dynamic routing, as well as static routing, but in both cases it does not work; My PC gets the 1. IP address, and I can ping the 1.
Linksys router's LAN IP address), and even ping 1. Linksys router's WAN IP address). But I cannot ping my Thompson router's IP (1.
Furthermore, from a PC in the 1. I cannot ping the Linksys router's WAN IP address (1. Do you have any ideas as to what the problem might be in this case? I have not defined any routes on the Thompson router, and no, I cannot change its internal DHCP network to use the 1.
It is locked I think from my ISP.
