Summary

APNIC

Australia · AI-generated

registry infrastructure anycast

APNIC-ANYCAST is held by APNIC (Asia Pacific Network Information Centre).

What it's used for

  • The space carries APNIC's own infrastructure, evidenced by the netname APNIC-SERVICES and the registrant APNIC Infrastructure Contact.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, dedicated infrastructure footprint rather than a transit or access network.

Notable

  • The registrant APNIC Infrastructure Contact aligns directly with the announcer, confirming the space is owned and operated by the registry itself.
  • The address inventory consists of a single /24 block (202.12.31.0/24) and one /48 IPv6 prefix, representing a compact, self-contained estate for the organization's services.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,852 prefixes, as published 2026-11-08. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
