Summary

NISZ

Hungary · AI-generated

government business infrastructure

KOPINT-AS is held by NISZ National Infocommunications Service Provider Private Limited.

What it's used for

  • The address space is registered under the netname HU-KOPDAT-20040614 with registrant NISZ National Infocommunications Service Provider Private Limited, indicating a corporate estate for a state-owned infocommunications provider.
  • The AS announces 65536 IPv4 addresses in a single /16 prefix (84.206.0.0/16) and maintains 4 observed neighbours, a ratio consistent with an internal corporate or government network rather than a transit provider.

Notable

  • The registrant NISZ National Infocommunications Service Provider Private Limited matches the registry holder, confirming consistent ownership of the announced space.
  • The operator was formerly known as Kopint-Datorg, a wholly state-owned IT company that changed its name to NISZ Zrt.
  • The inventory consists of a single contiguous /16 block with no IPv6 prefixes announced, reflecting a focused IPv4 estate for public sector services.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,773 prefixes, as published 2026-10-13. 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.
