Multiple IP ranges

Author: nethelp PostPosted: Thu Sep 27, 2012 10:48 am    Post subject: Multiple IP ranges

We have windows based network with DNS. We are using static IP addressing and currently we have IP like 192.168.0.x

Our network is growing and we are running short of IP addresses. We are planning to separate our wireless network with a different range, for example 192.168.1.x but we would like that users could access network resoruces on both the ranges.

Could anyone guide us how to setup this and best we can achieve this?

Many thanks in advance!

Very simply if you want all clients to be able to access resources on both: set the subnet mask to so that all 192.168.x.y addresses are treated as part of a single network.

If a client tries to access an IP in this range it will expect it to be on the LAN / WLAN.

If it needs an IP outside the range (eg on the interwebs) it will instead direct it's traffic to the gateway (which should be set to the internal address of your router).

If you have too many addresses for the range, then I would suggest you also have too many to manage static addresses properly and really ought to use DHCP. You would need to use reserved addresses for some devices like printers or continue to use static addresses for them, and make sure the DHCP pools do not include these to avoid conflicts.

Do you actually need to separate the LAN from the WLAN at all, or could you simply give out addresses from 192.168.0 to some clients and from ..1. to others (essentially at random)?
