Unanswered Question
Jul 14th, 2009

Hi all

can anyone tell me the rule of thumb for say. if I want lots of networks with say 512 hosts, so lots of big networks, and what do I do if I want lots of small networks.

what is the rule of thumb to work out how many networks/hosts i can get depending on how many I want?

I have this problem too.

You can use an IP Subnetter tool (there a few freeware programs available) to help you with this.
