Summary

Mathias Technologies

New Zealand · AI-generated

business nz leased

MATHIAS-NZ is the AS handle for Mathias Technologies.

What it's used for

  • The single announced prefix 101.193.96.0/22 carries the netname BSHNET with registrant IRT-CNNIC-CN, indicating the address space is associated with a Chinese network entity rather than the New Zealand holder.
  • The AS announces 1024 IPv4 addresses across 1 prefix and has 1 observed neighbour, a ratio consistent with a small, isolated business or internal network rather than a transit provider.

Notable

  • The RDAP registrant IRT-CNNIC-CN for the BSHNET netname differs from the AS holder Mathias Technologies, suggesting the address space may be leased or the AS is used to announce space registered to another party.
  • The inventory consists of a single /22 block, representing a compact and specific allocation.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
