Ok so i picked up a few videos and i'm getting to the subnetting. I have been watching these videos like i'm going to die if i don't watch 24hours of video in a week.
So i get the concept of subnetting but lets be honest when am I or a company going to need 40 networks with with only two useable host bits?
A question i was asked was to find out the range of ip's you can use for a network requiring 40 networks on an ip of 200.1.1.0 running on a class C network.
So, after coming up with the answer of 200.1.1.0-200.1.1.3 and a subnet of 255.255.252.0. So i can't use the 1.0 and i can't use the 1.3 so that only gives me 2 ip's that i can use on that network.
Has anyone ever had to deal with 20 routers at the same time? (this is good for a router->router connection) I understand that this is just good learning but i have meet alot of network admins and they have never used this math to get the answer. So should i start using this math and any pointers on getting the solution that i came up with to save any time?
