If someone is using your wifi connection, he/she will be on your LAN with appropriate IP fro myour LAN's DHCP. An exterme measure I would like to mention would be to close down DHCP and take complete charge of assigning fixed IP to equipment on LAN. However this gets to complicated for anything but a trivially small LAN - e.g. home network would be ideal candidate. I use this for my home network along with other safeguards. Only issue I have faced till now is to add a friend's laptop when he/she visits but that is trivial. I assign another IP when I permit the MAC on the network. Oh and one more thing, if a friend does not want me to mess with his/her computer for IP assignment, no connection for that PC.

Actually, since I was the author of the query to Leo about this issue, I thought it might be helpful to announce that Leo is (as is almost always the case) dead on in his remote analysis. The IP address at issue does, in fact, belong to a member of our LAN; namely. our Dandy Dell Laptop. However, I for one, at least, appreciate the additional comments provided above in re WIFi et al!

Uhm, Rahul, that is what I meant with my first post ;-)
I probably wasn't clear enough, sorry.
Anyway, forget mac filtering too, it isn't secure either, trust me...

One more point - It could be a hacker connected to your LAN through your router's WiFi connection. Is your router's wifi security enabled? Is it WEP - which is easily broken? If your LAN does not have a PC with IP .105, this could be the case.

Quickly enable WPA security on your router. If that is not possible, change your router to one that gives this level of security. Another protection is to enable MAC filtering on your router to allow only those devices whose MAC is known to you and you have configured it on your router.

If you are not using WiFi, just disable radio on your router.

If you have a wireless connection it's possible that someone else has hacked into your network and is trying to break into your computer.
I thought I should mention it because it happened to me once...
