69.56.130.138 resolves to ns3.escaped.net

Don't know what it is, but it's been pounding the heck out of my site lately. Any clues?

... have not seen this bot yet by myself, however the following seems odd and strange:
69.56.130.138 resolves to ns3.escaped.net,
but ns3.escaped.net resolves to 69.28.174.206 instead of 69.56.130.138.
The 69.56.130.138 belongs to theplanet.com (NetRange: 69.56.128.0 - 69.56.255.255, CIDR: 69.56.128.0/17)
