Summary

Asia Commercial Bank

Viet Nam · AI-generated

bank business vietnam

ACB-AS-VN is operated by Asia Commercial Bank.

What it's used for

  • The address space carries internal corporate infrastructure, identified by the netname ACB-VN and the registrant IRT-VNNIC-AP.
  • The AS announces 512 IPv4 addresses within a single /23 prefix and 1 IPv6 prefix, maintaining 4 observed neighbours.
  • This inventory supports the bank's internal network operations, including office connectivity and internal service endpoints for its banking operations in Vietnam.

Notable

  • The registrant IRT-VNNIC-AP is the national Internet registry for Vietnam, which is consistent with the AS being allocated to a domestic Vietnamese entity.
  • The address inventory consists of a single contiguous IPv4 block and one IPv6 prefix, indicating a consolidated corporate estate rather than a distributed access 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
