Summary

Taiwan Mobile

Taiwan, Province of China · AI-generated

mobile telecom residential business

TAIWANMOBILE-AS is operated by Taiwan Mobile Co., Ltd.

What it's used for

  • The address space carries mobile and fixed-line services, evidenced by netnames TAIWANMOBILE-NET and TFN-NET associated with the registrant IRT-TAIWANMOBILE-TW.
  • The AS announces 541696 IPv4 addresses and 39 IPv6 prefixes, with only 2 observed neighbours, indicating a large access/eyeball network rather than a transit provider.

Notable

  • Registrants for the largest prefixes include IRT-TAIWANMOBILE-TW for TAIWANMOBILE-NET blocks and unknown for TFN-NET blocks, both consistent with the operator's identity.
  • The inventory consists of 73 IPv4 prefixes and 112 announced blocks, primarily in the 49.214.0.0/16 and 101.8.0.0/14 ranges, reflecting a substantial corporate estate for a major mobile carrier.

Reputation

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
