One other option that is worth mentioning.. If you are an Arin member
(i.e. you have an ASN) then you can use Arin's Route registry services.
These services are currently free to members.

Thank You! a common sense answer I had not had hit me over the head. yet.
I needed that.. might as well get my money's worth from ARIN 
Just for clarification, ARIN's Routing Registry is available to any
organization or entity, and is not reserved for use by its members only.
Currently there is no fee associated with registering in the ARIN RR.
For further details, please refer to the following link on ARIN's
website:

Also worthy of mention is Steve Rubin's most excellent ALTDB service,
available free of charge (though I'm sure donations would be
appreciated :-)...
