John et all, 198.32.187.0 is exchangepoint IP space. At some time enkido was probably connected to MAE-E-ATM, then disconnected and returned their IP address to the IX pool. The IP was re-assigned to Exodus when they upgraded or purchased a second IX connect to MAE-E-ATM and DNS never updated for the .119. (There are many of them like that).

I believe I've found two administrative boo-boos.

Problem #1: The hop above is showing up for traces into an exodus.

..snip Quite possibly a leak on enkido's part. Have you tried regular problem resolution methods (shooting an email to both noc@enkido and noc@exodus) before posting to Nanog?

Problem #2: It looks like Winstar is announcing EP space.

they arent advertising the space to any peers. they ARE however carrying the route internally and advertising it to those who purchase transit from Winstar. Perhaps this would be best resolved by contacting noc@winstar? -troy http://www.clownhammer.org
