There's no way to effectively change it from a command prompt. You could use the ipconfig release and renew commands, but chances are you're just going to get your old IP address back, especially if you are behind a router or static IP.

Why would you want to do this anyway out of curiosity? The answer might help you get better ideas.

Hi

The NETSH command does this. This is its helpfile:

Quote:

Commands in this context:
.. - Goes up one context level.
? - Displays a list of commands.
abort - Discards changes made while in offline mode.
add - Adds a configuration entry to a list of entries.
alias - Adds an alias.
bridge - Changes to the `netsh bridge' context.
bye - Exits the program.
commit - Commits changes made while in offline mode.
delete - Deletes a configuration entry from a list of entries.
diag - Changes to the `netsh diag' context.
dump - Displays a configuration script.
exec - Runs a script file.
exit - Exits the program.
firewall - Changes to the `netsh firewall' context.
help - Displays a list of commands.
interface - Changes to the `netsh interface' context.
offline - Sets the current mode to offline.
online - Sets the current mode to online.
popd - Pops a context from the stack.
pushd - Pushes current context on stack.
quit - Exits the program.
ras - Changes to the `netsh ras' context.
routing - Changes to the `netsh routing' context.
set - Updates configuration settings.
show - Displays information.
unalias - Deletes an alias.

The following sub-contexts are available:
bridge diag firewall interface ras routing

Works in a batch file too. I used to use this all the time but I lost all my batch files .

Examples:

Quote:

netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0 192.168.0.1 1

to set a static address or

Quote:

netsh interface ip set address "Local Area Connection" dhcp

to set it to DHCP. Its a great command to have a link to on the desktop if you frequently move between static & DHCP networks etc. I used to use it a lot when i was configuring firewalls and needed to quickly switch my machine between outside & inside subnets.

Hope that helps!

We are not going to help you get around craiglists website set-up. If you have an issue contact the admins over there and see if they would be willing to change the rule.

By the way, this is on the subject of changing your LAN ip. Your external IP is set by your ISP and you cannot change it. That is the IP craigslist is seeing.

Hi all,

I have used the netsh command menssioned before. I also provide the proper ip address, mask and gateway then also got the following message :

"The syntax supplied for this command is not valid. Check help for the correct syntax.

Usage: set address[name]<string>[[source=]dhcp| static [addr=]IP address[mask=]IP subnet mask][[geteway=]<IP Address>|none [gwmetric=]integer]"

But when I used 'set address' command it work properly but the ip address doesn't changed.

Can any one help me to change ip address from command line. Thanks in advance.

Which IP are you trying to change? You can not change the IP given to you by your ISP. You are probably tring to set an IP on an adapter that has already received an address from DHCP - that won't work.

Here is an example if you want to change IP to 192.168.142.102, subnet mask to 255.255.255.0 and gataway to 192.168.142.1
netsh interface ip set address "Local Area Connection" static 192.168.142.102 255.255.255.0 192.168.142.1 2

Let me know if you have question

Hi . I think this info also will be usefull for you . Show that you can change dns server addresses from CMD as well as you can change an IP address . Show your boss him you are a cute guy .

To change DNS server addresses from cmd type next:

1.netsh
2.interface ip set dns "local area connection" static <IP address of a DNS server>

You can even add other DNS servers from cmd.
To do this type next:

1.netsh
2.interface ip add dns "local area connection" <IP address of a DNS server>

You could actually use an ip changer service like http://www.iprivacytools.com to change your "external ip", which it does by routing your traffic so that your ip simply "appears" differently to websites.

To the guy that wanted to change your ip address to flag on craigslist: if the posting you wish to remove is a bad one, then others will flag it too, and it will get removed eventually. That's how the system works.
