Summary
Internet Technology Laboratory
research education transit
ITLAB-AS-AP is operated by Internet Technology Laboratory.
What it's used for
- The address space carries research and educational infrastructure, with registrants including
PANGWEITSAI-TW,AMPRNET,ASSMAU-NET, andTIH-NET. - The AS announces 1280 IPv4 addresses and 3 IPv6 prefixes, peering with 16 neighbours, a ratio consistent with a transit or research network rather than a large access provider.
- Traffic originates from an educational and research institution, supporting academic projects and specialized network experiments.
Notable
- Registrants vary across the announced prefixes, with
Pang-Wei Tsaiholding the largest block andAmateur Radio Digital Communicationsholding a separate /24. - The address inventory is small and fragmented, with prefixes located in both Taiwan and the United States.

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.
