Summary

Vietserver

Viet Nam · AI-generated

hosting business vietnam

VIETSERVER-AS-VN is operated by Vietserver Services Technology Company Limited.

What it's used for

  • The address space carries business and hosting traffic, evidenced by netnames such as VIETSERVER-VN, TCLOUD-VN, HELI-VN, VNB-VN, PTH-VN, and SKY-VN.
  • The AS announces 23552 IPv4 addresses across 40 prefixes while maintaining only 2 observed neighbours, a ratio that indicates a hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints for corporate clients and hosting services, supported by the operator's provision of high-speed Ethernet infrastructure.

Notable

  • Registrants for the majority of prefixes are IRT-VNNIC-AP, while some blocks like 103.57.128.0/22 and 157.10.48.0/22 list APNIC Hostmaster or Internet Assigned Numbers Authority as registrants.
  • The inventory is composed of a mix of /22 and /23 blocks, with the largest prefixes being /22s and the remainder being /23s, reflecting a segmented corporate and client estate.

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.
