I'm a client on a network and i have the assigned ip of 10.10.10.37 and i want to change it.

I have admin rights also for the server so i'm curious now how do i change my ip address and i DONT want it static.

If i release and renew it still comes back .37


please help.
 
Ask a server Administartor to check the DHCP configuration and assign you a new IP address.

Thats my point. As administrator how do you do it?
 
I'm assuming this would work:

Get the user to log off, go into dhcp on the server, address leases and delete the ip address.

Hopefully when the user would log on, he would get a new ip address

wont work. dhcp ip stays with you unless someone steals your ip address when they log onto the network.

i see the dhcp detail on the server but it only gives me an option to refresh or delete.

Dont think i wanna delete.
 
Why do you want to change it, changing it manually may end up with an IP address conflict, worst cast case being you pick the IP address of a server etc.

but its dhcp it will only give me an ip address of an 'available ip'. No conflicting if you assign by dhcp unless something i decide to 'create' a static ip and not realise its an already assigned IP (which i wont).
 
Just go into the logs on the DHCP server and delete the lease... it should be random, but the server recognizes the MAC address of your NIC and assigns the same IP as it has previously.

You could try assigning a static IP, leave it for a minute then requesting one from the DHCP server again? Might overwrite the current lease, although i'm not sure! Actually I don't think that will work, because by giving yourself a static address your not actually informing the DHCP server of this so it will be none the wiser, unless the server attempts to lease that IP to another workstation... upon which it'l learn from that workstations response that its currently in use on the network.

Best way of doing it is adding your current assigned IP to the excluded IP list on the server! Then requesting an IP from the server and once you have a different one, log back onto the server and un-exclude that IP :)
 
To provide a conclusive answer we would need to know more details re: what type of DHCP server you are running i.e. is it UNIX or Windows?

A couple of things to look at would be the lease time (how long a particular DHCP lease is valid before a new one is issued) and whether your machine is listed as being statically assigned a particular IP address.

OK but why do you want to change it?

Firstly, Its windows server 2003.
Secondly, i dont know how long the dhcp lease is..how can i find out?
Thirdly, my machine is assigned dhcp it has no static IP.
 
You got access to another workstation? I'm not sure if you can change the settings to static, but if you can....

Turn your LAN off on your machine, on another machine assign the IP you don't want statically to that machine... then enable the LAN again on your machine... and you'l get a different address ;) Then just set the original machine back to obtain from DHCP.
