    changing ip addresses

    In the summer we have to change the ip addresses of everything on the academic network in order that our computers can be part of the network on the county router. This will fix a bunch of things that don't work through our proxies and generally simplify the network.

    I'm not sure what the best order to change things in is, or maybe use additional ip addresses on the servers?

    as it is printers, laptops, half the computers are on dhcp already so we can just delete the scope and make a new one.

    whats left is servers, switches and some computers. any computers we reimagining/updating to win7 we putting on dhcp so it'll be what's left that will need changing to dhcp.

    Any thoughts about order/how best to change servers & switches?

    thanks.

    I used this order from this thread and it worked a treat. Broadband install: need to change IP ranges

    My process was:

    Statically set a laptop my current range and run Angry IP Scanner on the current range (just to get everything)
    Change the servers IPs to the new range
    Change the DHCP scope to the new range
    Change any reservations
    Turn the switches off/on again (This causes a re-lease on every device)
    Re Run the IP Scan
    Change the important devices in the left overs list first
    Change the IP Printer ports on the print server
    Re Run the IP Scan
    Plod through the remaining devices and change them
    Repeat Steps 9 & 10 until the IP Scan returns only the laptop you set statically

    thats a handy thread. I need to check how the switches work with dhcp. could switch them off statics beforehand.
