Summary

BayCity Communications

New Zealand · AI-generated

telecom rural isp nz

The AS handle BAYCITY-AS-AP is held by BayCity Communications Limited.

What it's used for

  • The address space carries netnames ONENZ-NZ with registrants identified as One New Zealand Group Limited, indicating the IP inventory is managed under the One NZ umbrella.
  • The AS announces 44,544 IPv4 addresses across 5 prefixes while maintaining only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of connectivity for rural businesses, government entities, and remote locations in New Zealand, delivered via satellite and other fixed-line technologies.

Notable

  • All five announced prefixes list ONENZ-NZ as the netname and One New Zealand Group Limited as the registrant, which differs from the AS holder name but reflects the corporate relationship.
  • One New Zealand Group Limited acquired BayCity Communications Limited, integrating the rural connectivity provider into the broader One NZ telecommunications group.
  • The inventory consists of five distinct IPv4 prefixes with no IPv6 prefixes announced, representing a consolidated block of address space for the operator'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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
