[44net] DNS Cleanup

Returning to the perennial subject of cleaning up the AMPR.Org DNS database, Neil Johnson has done a thorough job of investigating the entries in the current database. He has generated a file available from the gw.ampr.org anonymous FTP server "Hosts-TBD.txt" which lists 2,045 callsign-based entries in the DB where 0. They're in the current AMPR.Org DNS. 1. They're not found in active entries on QRZ.com. 2. They're not found in the online Callbook database. 3. They're not in the portal. 4. They're not in HamNet.de. 5. They were NOT entered into the AMPR.Org DNS after 2011. 6. Or they are listed as expired in QRZ. This is about 5% of the database. Not a large amount but a definite place to start. I propose to delete these entries from the AMPR.Org DNS around July 1st. - Brian
