What are my available ip addresses?

[confuseddude]

I have a 10.1.1.0 Scheme with a subnet mask of 255.255.0.0

What are my available IP Addresses, of course I know I have 10.1.1.0 to 10.1.1.254, but what are the rest?

If I know my networking correctly, you should have at least 10.1.x.y available, where 1<=x<=254 and 1<=y<=254. I am unsure if x can be 0 and/or 255. Basically, it looks like the following addresses are available locally with 10.1.1.0 IP scheme with a 255.255.0.0 subnet:

10.1.1.1 to 10.1.1.254
10.1.2.1 to 10.1.2.254
...
10.1.253.1 to 10.1.253.254
10.1.254.1 to 10.1.255.254

Hope this helps

NickIstre is right about your address, you have

10.1.1.1 to 10.1.255.254

What you are doing is Subnetting a TCP/IP range. 10.1.1.3 is in the same subnet as 10.1.102.78, for example.

There are several useful purposes for this:
IE 10.1.1.x is your servers
10.1.2.x is your Hubs/Switches
10.1.3.x is your Printers
10.1.4.x is computers you don't want to have web access
10.1.5.x is computers you want to have web access
or you could divide by floor, or department, or what ever.

To answer a question about subnets, not they do not have to be 0 or 255. There is a range of numbers.

One of the best ways to understand subnets is to do a search on subnets. If you want to do some quick computations, go to

http://www.solarwinds.net,

under free tools, they have a SubNet calculator. This should help to explain how subnetting works a little bit, and what else can be used in place of a 255 or 0. Tom Backus
