Re-numbering I.P. Address on our LAN

Hi All,

I wonder if you could give me some advice please. My boss has told me to re-number the whole LAN at our company this involves changing the I.P. Addresses of the Servers, Print Server, Routers etc. Fortunately most of the workstations are currently on DHCP so we can just change the definition in the DHCP Server. Could you please recommend the best way to approach re-addressing the above with minimum disruption to the users?

We currently have  6 windows 2000 servers, 1 pix firewall, 1 1760 cisco router, 150 workstations.

Also what I.P. Address blocks would you allocate to the below:-
(I current have been given this range 192.168.165.0 - 192.168.167.254 )
Network Devices
Servers
DHCP Allocation
Print Servers

Thanks in advance

Aaron.

ohh forgot something you asked how would I do it with less impact on the user's

change the router first setup one server with the new IP DHCP scope turn the other off in the morning when the users come in all get the new scope.

Add additional routes to the router for the old address scope so they can work the day out, then change IP addresses on the rest of the servers.

Hello,

I have got the same problem as I joined a new company a week ago and realise they are running our of address space.

they are running 192.9.100.* addresses on a 255.255.255.0 subnet. I have recalculated the subnet range the be 192.9.100.0/23.

I need to implement this with minimum down time. I will not be changing the addresses of the routers, switches or Domain controllers. DHCP is running on the network with some static addresses.

Need all your expert advice.


many thanks
