Summary
Quang Trung Software City Development Company
business vietnam software corporate
QTSC-AS-VN is the autonomous system for Quang Trung Software City Development Company.
What it's used for
- The address space carries the corporate infrastructure of Quang Trung Software City, a major technology park in Ho Chi Minh City, as indicated by the consistent
QTSC-VNnetnames across all listed prefixes. - With 33,280 IPv4 addresses announced against only 4 observed neighbours, the ratio suggests an internal corporate estate or access network rather than a transit provider, consistent with the finely subdivided inventory of 38 IPv4 prefixes.
Notable
- All registrants for the largest prefixes are listed as
IRT-VNNIC-AP, which is the Internet Registry of Vietnam, indicating the address space is allocated via the national registry rather than held directly by a different entity. - The address inventory is heavily concentrated in the
210.2.0.0/16and120.72.0.0/16ranges, with the largest block being210.2.64.0/19, reflecting a structured internal segmentation typical of large corporate campuses.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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.
