If you're wondering why it has a PTR record of gtei.net then here's a little history.
It was originally owned and hosted by a provider called BBN Planet.
BBN was acquired by the General Telephone & Electronics Corporation in 1997 and became a sub-division of GTE known as GTE Internetworking. Hence the GTEI domain.
GTEI was spun off into a separate company called Genuity in 2000 when GTE was aquired by Verizon.
Genuity filed for bankruptcy in 2002 and was bought by Level 3.
