It would be a good idea to recover the ip address numbers that have never been used. I would also suggest that within 90 days of issuance the numbers must be in service or they are recalled. I mentioned to the Nic that there are several class B numbers out there being used as a "status symbol" , not for the purpose stated. All I hear is lets talk about not and not the past. For international X.25 services NET-99 required a DNIC number. The FCC inserts a clause states the following: all DNIC assignments are provisional and no assignee obtains an ownership or property interest in a DNIC assignment. As a rseult, the DNIC herein assigned is expressly subject to possible revocation or reassignment as may be required because of a shortage of DNIC's or as otherwise required in the public interest. If you fail to agree, you don't get a number. Throughout the FCC letters there is a constant mention of "this scarce DNIC resource may necessitate reassignment of codes not implemented within a six-month period. Now if the FCC has been doing this I am sure we could work out something with the Nic. Joseph Stroup
