Change network IP address

By cyntomcomputer ·
I have to change my network's IP address from, say, 192.168.1.1 to 192.168.10.1.
I have NT 4.0 sp 6. I have dhcp, with a rang for 50 workstations.
I tried to change it, but obviously incorrectly. Please give me step by step procedures or a location to get it. Thank you!

Change network IP address

1) Change the servers address to the proper network. ie: 192.168.10.10

2) In DHCP manager de-activate the current scope

3) Create a new scope with the range 192.168.10.1 to 192.168.10.254

4) Exclude enough to take care of all static addresses ie: exclude 192.168.10.1 to 192.168.10.49 (allowing 49 statics)

5) Setup scope parameters for router (gateway address) DNS (server dns) and Wins (number 44 and 46) Make sure to setup addresses on each parameter. The Wins server should be the server IP address and the Node type should likely be 0x8.

6) If you changed the server's ip address make sure that you change the server's Wins server address to the same number also.

7) Activate the scope and login from a workstation.Do an ipconfig from Windows 2000/NT workstations or winipcfg from Win9x machines to determine if they are receiving proper addresses from the DHCP server.

If this is not enough detail, please respond with specific questions. You may reboot the server just to make sure everything is restarted. Beyond this if DHCP is not handing out addresses MAKE SURE there are no other DHCP servers on the network. This may become apparent when you do IP Config or Winipcfg. There have been a couple of instances when I have had to reinstall DHCP to get it to work but only as a last resort.

This is a decent start. Good Luck!

On your DHCP Server, add the new IP range (minus the addresses that you will statically enter for printers/servers,routers,etc...).
Do this during non-work hours...
1) Change the IP's for the static devices first
2) Enter the range for the new IP's on your DHCP server.

Example: 192.168.10.1-192.168.10.10 = Static addresses for servers, etc..

192.168.10.150-192.168.10.250 = Client Dynamic range (never use the minimum # of addresses needed. If you have 50 clients...setup 55 or more for the range.)

Hope this helps!

Also, leave room for growth of devices that will need static IP's. If your company is going to possibly add servers in the future, then allow for that growth.
