Summary

Industrial Technology Research Institute

Taiwan, Province of China · AI-generated

research education business

The AS handle ITRINET-AS-TW is held by Industrial Technology Research Institute.

What it's used for

  • The address space carries research and institutional traffic, evidenced by the netnames ITRI-TW and ITRINET-NET and the reverse DNS record 240.254.seed.itri.org.tw.
  • The AS announces 69632 IPv4 addresses across 13 prefixes and 1 IPv6 prefix, with 11 observed neighbours, indicating a large internal corporate estate rather than a transit or access network.

Notable

  • Registrants for the 140.96.0.0/17 and 61.61.248.0/21 blocks are IRT-ITRI-TW and IRT-ITRINET-TW respectively, both associated with the Industrial Technology Research Institute.
  • The address inventory is finely subdivided into multiple /21, /23, and /24 blocks, consistent with site-by-site segmentation for a large research organization.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
