used to be. ep.net has fragmented into little bits. most of the prefixes have
been transfered to the clients who were using them, the ones who are still around
are outside the ARIN region and there is no clean way to move them given ARIN and
other RIR policy.
This particular prefix was used as a public exchange, operated by Switch & Data. Not sure
what they have done w/ it since then.
