Summary

Unison Networks Limited

New Zealand · AI-generated

business nz ipv4

The AS handle UNISON-NZ-AP is held by Unison Networks Limited.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to unison.co.nz and the netname UNISON.
  • The network announces 1024 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small-scale business or internal corporate estate rather than a large access or transit provider.
  • Traffic from this AS consists of internal corporate endpoints and services operated by Unison Networks Limited.

Notable

  • Registrants for the primary prefix 103.22.234.0/23 align with the announcer, listing UNISON NETWORKS LIMITED. The secondary prefix 203.92.24.0/23 is registered to APNIC Hostmaster with the netname APNIC-AP, suggesting leased or allocated space from the regional registry.
  • The inventory consists of two /23 blocks, one under APNIC management and one directly under the operator, with no IPv6 prefixes announced.

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: 442 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.
