Re: odd ip in tracert

That's the IP address for your local UBR. It's supposed to be there. ;)

Re: odd ip in tracert

My guess is thats the IP Address of the UBR of your connection.

Quote:

the local UBR's private IP address in hop 1 will be slow to appear, because Windows does a reverse DNS lookup on the IP number, but gets no reply from the DNS system, because addresses in the range 172.16.0.0 - 172.31.255.255 and 10.xxx.xxx.xxx are private IP addresses (rather than public internet IP addresses) and are not registered in the DNS system. There will be similar slow responses for all hops with IP addresses in private ranges.

Mine is similar.
