How do you create sub-networks?

[Filingo]

How can you create sub-networks? What I mean is that my router provides IP addresses that begin with 192.168.10.x, but what if I want to use 192.168.5.x for example, for certain computers in the network?

 

Thanks!

You will need your own router to do this. most advanced/buiness routers support creating multiple networks.

Telling us which router you got would be a good start.

What's the goal?

 

You can shorten the subnet mask and make a wider choice of addresses be in the same network.

 

For example if you set the mask to 255.255.254.0, both 192.168.0.x and 192.168.1.x will be in the same network.

If you want 192.168.10.x and 192.168.5.x to be in the same network you need a mask of 255.255.240.0.

Routers route between networks.

Switches switch within networks.

 

Switches can do some routing, though, like vlans and layer-3 switching.

 

I'd say if you want to play with it look at software-defined networking, you can run a lot of that in a VM.

If you want hardware, get a smart switch that supports vlans.

sub-networks, or subnets, can have many different ranges.

You need a router with non-ISP specific firmware to have full control over your network in many cases.

 

You can pick any subnet you want as long as you pick from the non-internet routable ranges.

If you want more subnets for different tasks in the same physical network, you need to create VLANs, and routers and switches that can deal with them.

What kind of application do you need this for?
