I am a co-owner for a medium sized business and we want to make the private network RFC 1918 compliant.

First, are you using public IPs on things now? You'll have to turn NAT on all routers so they can access the Internet.

When you say 6 branches, are they all located in the same locale or are you saying they are in the field?
Remote means that you probably want to VPN to connect them together and you need to come up with
a coherent IP addressing scheme. Do any of the offices have subnets, you need to take that into account because you need networks for the routers.

You need to talk to a professional network engineer/architect. My group did the same thing (world wide) and
it takes planning. Doing it as home is easy.

In network settings on your computer. Select Static IP and give it an IP that's isn't already used or in the DHCP pool..

You woulld need to change all the addresses if you change the network address. And the netmask.

depends on the router you are using… some dont allow you to change it others do
