You're right, they're wrong. As Mark says - probably the message has 
become garbled.

The only think they *might* be referring to is appropriate inetnum: 
entries in the ARIN DB, which are used to drive permissions for both 
route: objects (which some providers use to build filters) as well as 
reverse delegations.
