Viet Nam · AI-generated

business securities vietnam

VCBS-AS-VN is the autonomous system for Vietcombank Securities Company Limited.

What it's used for

  • The address space carries corporate infrastructure for a securities firm, with the netname VCBS-VN registered to IRT-VNNIC-AP.
  • The AS announces a single IPv4 prefix, 103.221.212.0/22, comprising 1024 addresses, and maintains 4 observed neighbours.
  • Traffic from this AS consists of office workers, web/API endpoints, and internal systems supporting brokerage and investment banking services.

Notable

  • The registrant IRT-VNNIC-AP is the national Internet registry for Vietnam, which is consistent with the announcer's identity as a Vietnamese entity.
  • Vietcombank Securities is a 100% subsidiary of the Bank for Foreign Trade of Vietnam (VCB).
  • The inventory consists of a single contiguous /22 block with no announced IPv6 prefixes.

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 1,784 prefixes, as published 2026-10-19. 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.
