These days I had problem with my internet connection.

I have a static IP connection, but some time ago I couldn't access the internet. A friend helped me and we found out that the IP and MAC-address of my PC were assigned to another user in my network.

This user is using some program which is giving him this precious information of mine (i.e. the addresses). The Ubuntu PC in question is acting like a web server and I need a way (if there exists one) to hide this important information, since I need my server to run all day with active internet connection.

The ISP can't avoid this problem.

someone needs to give up their static IP. Can you find out why the other user is using a static IP? – tombull89 Oct 25 '11 at 11:21
There's not a way to hide the MAC/IP from your end. The service provider could do it in a couple of ways...but you're indicating that the service provider is being less than helpful. You could come at the problem another way and use dyndns or something instead of a static ip. – aking1012 Oct 25 '11 at 11:57
This connection was not user for a long time. And my solutions are. One: to block the ip with my friend help and hope the user steals somebody else mac/ip. Two: now i use dynamic dns, update 2h, on static ip. Suggest to opt for dynamic dns and dynamic ip? – mjonutz Oct 25 '11 at 12:14

Who's paying for the IP? If you're paying, and your friend is stealing it, he's not a very good friend. If he's paying for it, get your own! – Chris S Oct 25 '11 at 12:26
