Mystery IP address perhaps DHCP server in router?

Hi all,

In my personal home network that is connected through a router, there is always a mysterious standard IP address with the same MAC address. Since the router has DHCP functionality I was speculating whether that could be the IP address of a DHCP server within the router.

Wouldn't a router with built in DHCP-server need a separate IP-address for the DHCP-functionality, since its own address is already used as internet gateway?

DELL4600 192.168.1.100
Rene 192.168.1.101 <--- mystery IP address
green-pc-alrum 192.168.1.102
router 192.168.1.1 (internet gateway)

Hi,

Arp out the IP to the Mac and do a vendor code lookup... may give you a clue.

Hey,

Look on the sitcher on the bottom of the router and see what the MAC is meant to be....

Hope this helps,

Thanks, but I already figured it out. It turned out it was my neighbour. He also has a wireless network and ours overlapped. His name is Troels and his son is called Rene. These were exactly the host names that once in a while turned up on my network. :)

I think it is a bit funny, really...

Time to configure some security on the Wireless side don't you think?
