Summary

  • APNIC’s 2 November file linked AS133173, an IPv4 /24 and an IPv6 /48 to the same 2013 Australian holder record.
  • Its 3 November file marks all three reserved; APNIC defines reserved separately from available.

A registry can move three identifiers with one edit. In APNIC’s 2 November extended delegated file, Australian AS133173 was allocated on 27 November 2013. The next day’s dates appear beside 103.254.50.0/24 and 2001:df0:c800::/48, both assigned. All three rows carried the same opaque holder identifier, A915FBEA.

The 3 November file keeps all three resources but replaces their delegated states with reserved. The country, dates and holder identifier disappear from those rows. The public registry record now places each resource in a different status. APNIC’s status guide draws a hard line between reserved and available: an available resource is one that is neither delegated nor reserved. These three are on the reserved side.

The RIPE NCC routing snapshot queried at 16:00 UTC on 2 November found no RIS peers then seeing AS133173; its last recorded announcement for that origin was the IPv6 /48 on 27 March 2025. The two delegated files name no transaction or holder decision; an APNIC resource notice would identify the administrative trigger. An APNIC resource notice explaining the change would settle what put the three records in this drawer.
