How to change IP?

if it truly is dynamic and you are connected directly to a modem without a router inbetween, then start>run>cmd>ipconfig /release > enter > ipconfig /renew. Otherwise download MACaddresschanger and spoof the MAC of your local network adapter. This will reset the connection and give you a new IP. 

if you are connected to a router, then only your internal IP will change, that is 192.168.0.X and the external IP will stay the same. 

You cannot change your IP, the ISP changes their IP's at a set time, example:

• At end of every month
• When you disconnect (turn off modem) for a long period of time

You can always call them to change it for you.

Remember that changing your IP will not make you anonymous with the authorities... your ISP has logged each and every IP you used.

@Alcom4c : That does not work, unless your using an old Melita modem. Todays modems have an inbuilt router with their own routing table...

I am connected directly via modem and it's Melita's Cisco for the 25Mbps connection. And no it isn't about being anonymous, mostly to bypass certain simple IP bans that could happen in the future.

Use a proxy server, changing IP is ******ed

Unless you find a way to change the Cisco modem/router's mac address you won't get a new ip address unless Melita randomly decides to change ips, but Melita's Ip's do not change very often unless you change the mac address. Altough if you change the mac address of the cisco modem you might end up not getting any internet at all. I'd use proxies as MercyKiller101 said

If you do change the CISCO Modem MAC Address (which is impossible) you will have to call melita to re-register your modem on their system.

Call Melita and ask them to refresh you IP address, invent some excuse along the lines of "my webserver needs an IP reset as it's being blocked" and they will grant you an IP refresh. The refersh usually takes 24 Hours to work, unless you call at the exact time Melita is refreshing their servers, which in that case your IP will change immidiatly. Also after the 24 passes, restart your modem to get the new IP parameters...

Fave Hun!
