Im trying to set up a subnet address range in my local network but the private address ranges of 

172.16.1.1
192.168.1.1
10.1.10.1

are all already being used.

So I was wondering, if I make this subnet 172.17.1.1, will it be totally isolated from 172.16.1.1? and can I use both subnets without any problems? The subnet Im making now will also be a vlan.

Im just worried because I think I read somewhere that the first part of the ip address ranges cannot be the same.

thanks in advance.

It will depend on the subnet mask of the 172.16.1.0 network. If it is a /16 or longer, then 172.17.1 will fall outside the range and be fine to use
