This will save you alot of time and trouble, once you have used this for a bit you will see what you need to do to get what you need without need to do to much brain work.

For you first line you would have:

Netmask: 255.255.0.0 = 16 11111111.11111111 .00000000.00000000
Wildcard: 0.0.255.255 00000000.00000000 .11111111.11111111
Network: 164.14.0.0/16 10100100.00001110 .00000000.00000000 => (Class B)
HostMin: 164.14.0.1 10100100.00001110 .00000000.00000001
HostMax: 64.14.255.254 10100100.00001110 .11111111.11111110
Hosts/Net: 65534

That should get you started however you will notice that in your example your subnet mask is incorrect

It's best not to use the online ip calculators and to get used to doing it by hand. Also get used to doing the maths in your head or on paper that you'd use your ordinary calculator for. Just use the calculator to check it or you'll never learn how to do it yourself.

In the practical exams for CCNA etc you're not allowed to take in or use any calculators and you have to do it yourself (Well...I'm not allowed) so it's worth learning.

its not for ccna, i did this earlier this year, i dont wanna use a calculator as i wont be allowed a calc in the main exam

where i am getting confused is how to work out the network address and subnet address, i do not know which to convert

i have the host address and i know this needs to be converted to binary and added to either the supernet or the subnet mask but not sure,

below is an example i have done

11111111 11111111 00000000 00000000 (supernet)
---------------------------------------

i'm not sure if i 've worked out the network address or subnet address, your help will be much appreciated.

thanks.

i've had a go on the first example,

here's wot i have worked out so far

-----------------------------------------------

11111111.11111111.00000000.00000000 (Supernet)
-----------------------------------------------

have i dont this correctly?
