Summary

Taiwan Infrastructure Network Technology

Taiwan, Province of China · AI-generated

isp residential mobile cable

TINP-TW is operated by Taiwan Infrastructure Network Technology.

What it's used for

  • The address space carries residential and mobile access traffic, evidenced by reverse DNS entries such as tinp.net.tw, dynamic.tfn.net.tw, and adsl.dynamic.seed.net.tw.
  • With 309,248 IPv4 addresses announced across 180 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants align with the announcer, including tinp Network Administrator and IRT-TINP-TW, though some prefixes list unknown or unrelated netnames like NCICNET-NET and KGT-TW.
  • The inventory consists of a mix of /18, /19, and /20 blocks, with the largest being 27.100.64.0/18 and 60.198.64.0/18, alongside a single /32 IPv6 prefix.

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.
