Summary

Fastcom Limited

New Zealand · AI-generated

nsp new-zealand business

FASTCOM-AS-AP is operated by Fastcom Limited.

What it's used for

  • The address space is registered under the netname FASTCOM-AP with registrants listed as FASTCOM NZ LIMITED and Fastcom Limited.
  • The AS announces 15616 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with 11 observed routing neighbours. This ratio of address space to peering partners suggests a network provider role rather than a large-scale transit hub.

Notable

  • All registrants in the evidence pack align with the announcer, consistently identifying FASTCOM NZ LIMITED or Fastcom Limited as the network administrator.
  • The address inventory consists of multiple /20, /21, /22, /23, and /24 blocks, primarily within the 180.189.0.0/16 range, indicating a consolidated corporate or service provider estate.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
