[44net] DNS records 44.131.56.0/24

Hi, I've checked DNS A records for various hosts in the net that I'm co-ordinator for and they resolve but to to obsolete records. I've entered some new records via portal.ampr.org, expecting them to come to me for approval but as yet, no email! The correct entries should be - gw.g4irx.ampr.org IN A 44.131.56.9 g4irx.ampr.org IN A 44.131.56.10 Ideally the entire 44.131.56.0/24 block could be deleted as we've started afresh re-allocating addresses. Any suggestions to get this fixed? Thanks, Nick G4IRX.
