IP Scheme

We are currently running on a 192.168.1.* with 255.255.255.0 environment but I only have 38 IP addresses left. My question is how to expand or add too that so I do not run out of IP addresses.

so try to use different subnet mask - 255.255.0.0

Yes, as mentioned, you can change the subnetmask of your network to increase the amount of IP-addresses available to you.

either expand to a /16 as mentioned by helpfinder, which would give you the possibility to expand to 192.168.255.254, before you fill that you will have already have a grey beard :)

Or make it somewhat smaller, like a /22 for example, this will expand your network to 192.168.3.254 which means you have a network from 192.168.1.0 to 192.168.3.254. This allows you to (for example) use the entire 192.168.3.0 range as DHCP, separating it kind of from your other ranges ... This will give you 254 addresses.

But, before doing that, you need to know that implementing this means that you have to change the subnetmask on all your network devices, servers, routers, switches, printers, and so on ... Your clients will receive the info from the DHCP server so that's no problem.

We are a Vm shop with multiple vlans, will the above procedures have a conflict due to this?

That's a possibility ... Are these routed VLANs with a gateway on this same network for instance, you might need to adjust some routing ...
