Summary

Heineken Vietnam Brewery

Viet Nam · AI-generated

business corporate vietnam

VBL-AS-VN is operated by Heineken Vietnam Brewery Limited Company.

What it's used for

  • The address space carries corporate infrastructure for a major brewery, identified by the netname VBL-VN and registrant IRT-VNNIC-AP.
  • The AS announces a single IPv4 prefix, 203.34.144.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the network functions as a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, office workers, and business endpoints for the brewery's operations in Vietnam.

Notable

  • The registrant IRT-VNNIC-AP is the national Internet registry for Vietnam, which is consistent with the local operation of the AS.
  • Heineken Vietnam Brewery is a joint venture between Saigon Trading Group and Heineken Asia Pacific, with Heineken Asia Pacific holding a 60% share.
  • The address inventory is minimal, consisting of a single /24 block, which fits the profile of a specific site or corporate segment rather than a large-scale network.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
