Summary

Institute of Information Technology

Viet Nam · AI-generated

education research vietnam

IOIT-AS-VN is operated by the Institute of Information Technology (IOIT), a member institution of Vietnam National University, Hanoi.

What it's used for

  • The address space carries the internal network of the Institute of Information Technology, as indicated by the netname IOIT-VN and the registrant IRT-VNNIC-AP.
  • The AS announces a single IPv4 prefix, 103.220.68.0/22, comprising 1024 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour, the network functions as a small, isolated site network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of research, academic, and administrative endpoints associated with the institute's operations in Hanoi.

Notable

  • The registrant IRT-VNNIC-AP is the national registry for Viet Nam, consistent with the local holder identity.
  • The address inventory is compact, consisting of a single /22 block, which aligns with the scale of a university research institute.
  • The AS has been observed in routing tables since 2016.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, 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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
