You listed a MAC address, not an IP address
If you are seeing a MAC address as your IP address, then something got fucked. I can't think of any way at all that a system would list a MAC address as an IP address. Mac Addresses are basically social security numbers; IP addresses are basically housing addresses. One can be used to filter the other, but not vice versa.
Regardless, you need to provide more information
What router?
What firmware?
What settings did you use to set it up?
