Summary

TMA Solutions

Viet Nam · AI-generated

business software vietnam

TMASOLUTIONS-AS-VN is operated by Tuong Minh Software Solutions Company Limited.

What it's used for

  • The address space carries corporate infrastructure, indicated by netnames TMA-VN and TMASOLUTIONS-VN registered to IRT-VNNIC-AP.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 3 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and web/API endpoints for a software outsourcing company established in 1997, which provides services to global clients.

Notable

  • Registrants for both announced prefixes are IRT-VNNIC-AP, consistent with the announcer's identity.
  • The address inventory is finely subdivided into two /22 blocks, typical of internal corporate segmentation for site-by-site management.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,784 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.
