I am trying to access a website from an IP address that appears different than the normal one. I have tried using "sudo ifconfig up" and successfully changed the ip address, but then I wasn't able to use Firefox, it just kept on loading. So I reset my connection, the router restored my normal IP address (It stores my MAC and gives me the same IP each time). Now I am back to where I started. Any ideas.

Note: I have very little idea what I am doing. Tell me if the question doesn't make sense. Please to answer in beginner friendly terms.


You have two IP addresses; a local one (192.168.1.XXX) and a dynamic, public one from your ISP.

Websites you visit see your 'outside' address; not your 192.168.1.XXX one. If you want to change this address, try a DHCP release in your router. If you want to change your internal one, you could disable DHCP in your router or, ideally, create a DHCP lease so that you get a different IP every time.

For all of this, you should consult the documentation for your router. :-).

  • 192.168 addresses come under the private network addresses, basically meaning you can't use them over the net. You can read more about the RFC1918 here : en.wikipedia.org/wiki/Private_network – user155695 Nov 2 '09 at 16:45
  • Get so far, but how do I get a DHCP release in my router? Beginner terms. – The Green Frog Nov 3 '09 at 14:57
  • This will depend on the make and model of your router. For example, on mine, I click the 'Status' tab and then click 'IP Address Release'. You should consult the documentation for your router. – briealeida Nov 3 '09 at 16:57
  • What? What screen/menu/login are you coming from? Are you talking about when you are loged into the router? – The Green Frog Nov 3 '09 at 17:31
  • Usually you can login in your router. There is somewhere a menu where you can "update your ip address", "get a new release" or something similar. If you tell us your model, maybe we can give more specific advice. – qbi Jul 16 '10 at 16:08
