Question

Using different IP address ranges/subnets

I have 2 routers, and I want to have two separate ranges of IP addresses for different groups of devices.

Example:
Group 1: 10.111.114.XXX
Group 2: 10.111.122.XXX

What is the best way I can use to accomplish this?

Re: routers

Set each router's DHCP to give out the addresses you want. The user manual tells how to do that, if possible.

Do you know about subnets?

Answer
The easy way.

Get two internet connections and connect one router to one ISP and the other router to the other ISP. That works.

If you connect one more router say like this:
ISP -> First router and the next two routers to LAN ports, that also can work. But sometimes folk want a non-supported setup So you can also do:
ISP -> First router and then next router to a LAN port and configure but this does not assure the second LAN won't see the first LAN. Hence it takes 3 routers.
