Summary

VNNIC

Viet Nam · AI-generated

registry infrastructure vietnam

VNNIC-AS-VN is operated by VNNIC (Vietnam Internet network information center).

What it's used for

  • The address space carries registry infrastructure, evidenced by the netname VNNIC-NET and registrant VNNIC IPHOSTMASTER associated with both announced IPv4 blocks.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale internal or registry-specific network rather than a transit or access provider.

Notable

  • Registrants for both IPv4 prefixes are IRT-VNNIC-AP and VNNIC IPHOSTMASTER, which align directly with the AS holder identity.
  • The address inventory consists of two /22 blocks in the 203.119.0.0/16 range and a single /47 IPv6 prefix, representing a compact and consistent allocation for the registry's operational needs.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
