Summary

Vietnam Internet Network Information Center

Viet Nam · AI-generated

registry nir infrastructure

VNNIC-AS-AP is held by Vietnam Internet Network Information Center.

What it's used for

  • The space carries the registry's own infrastructure, identified by the netname VNNIC-NET and registrant IRT-VNNIC-AP.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with 1 observed neighbour, indicating a small, self-contained network footprint.
  • Traffic from this AS consists of internal registry operations, including IP address management and .VN domain name services for the Vietnamese internet.

Notable

  • The registrant IRT-VNNIC-AP matches the announcer, confirming the space is owned and operated by the National Internet Registry of Viet Nam.
  • The address inventory is compact, consisting of a single /22 block and a single /48 prefix, consistent with an administrative body rather than a large-scale access provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
