multiple IP ranges on one network

Posted on 2011-10-12

Hello all, probably a simple/ stupid question this but.....

at the moment our main network (all housed in one large building) uses the network. we also have vpn's connected through our routers using: etc

in our main office the range is becoming full so i would like add an additional range to our ip range.

i have only ever done this through a router an added routes on each server.

how would i go about creating a new range of ips within an existing network? is this where a vlan comes into the equation?

most of our switches are Netgear GS724TP. we also have Linksys/ Cisco SRW switches too

    Accepted Solution

    You have two choices

    1. Assuming you have DHCP environment and Free Consecutive IP Range e.g.

    You could use it by changing the subnet mask to

    2. If your Network Switches has the capability to create VLANs
    you could create a new VLAN with new IP Range
    and configure inter VLAN routing.

    I would personally recommend 2nd option as it helps reducing unnecessary broadcasting on network.

    Hope this helps!
