  • Over 254 PC

    Hello,
    I would like to ask what I have to do in order to have more than 254 pc in the same network.
    I have 300 pc with static IP (for example 172.100.100.1-254) and I have one proxy server (dsl router 172.100.100.1 and one dns server 172.200.200.1).
    How am I suppose to have all the pc's in the same network(all pc's is more than 300).

    Thanks

    What is your subnet mask?

      keep the 24 bit subnet mask & incorporate vlans - this one's alot of work!
      you'll need a layer 3 switch to handle routing & you can use a different subnet for each dept or floor or whichever way you'd like to segment the network

        And what is wrong using a 23bit mask? All that needs to be changed is a new DHCP scope with the appropriate IP range and new Mask, any Static IPs (change masks) and reboot the DSL Router.

        If you think you may need more IPs in the future choose a 22 bit mask.
