hello everyone
i'm kinda new here, and i was just wondering:
i had this test yesterday, and i was supposed to figure out the ip, subnet mask, subnet and broadcast of the 220th ACTIVE subnet, knowing that the ip subnet zero command had been used
so, which is the 220th active subnet? i mean, what value does it have? 219 or 220? aaaand most importantly do you happen to know any site which might explain it? just in case i got it right, so i can show it to my teacher as proof
thanks in advance

Strangely worded question, so you need a minimum of 220 subnets.This means you will need a block of 256,following 2's complement 2^8.So if you had a class b address like
130.1.x.x/16 if you wanted to subnet this to get the 220th subnet you would add 8 subnet bits. 130.1..x.x/24. So the 220th subnet would be 130.1.220.x/24Networking, sometimes i love it, mostly i hate it.Its all about the $$$$
