I have been reading about subneting and would like to do it at home. Here is what I have so far. I Have A IP Address of 192.168.1.71 subnet 255.255.255.0

11111111.11111111.11111111.11111111 I Want 20 IP Address.

So my subnetmask is

11111111.11111111.11111111.11111000

255.255.255.248

What would be my IP address be and default gateway

192.168.1.????

248 = subnets going up in 8s.
192.168.1.72 is the network number, 73-79 is the range, default gateway ought to be 73, though that could be any of the allowable IP addresses in the range according to your preference or router config.

If you want 20 IP addresses in each range your subnet mask will be 255.255.255.224

192.168.1.71 is a broadcast address given your original subnet mask, and as such not available for use. 192.168.1.64>72
