Summary

FarEasTone Telecom

Taiwan, Province of China · AI-generated

mobile residential telecom taiwan

APT is the AS handle for FarEasTone Telecom, a major telecommunications provider in Taiwan.

What it's used for

  • The address space carries mobile and residential customer traffic, evidenced by reverse DNS entries such as 218-184-64-0.cm.dynamic.apol.com.tw and netnames like FET.
  • With 332,288 IPv4 addresses announced across 86 prefixes and 31 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of the largest prefixes, including 218.184.0.0/16 and 210.85.128.0/17, are listed as IRT-FET-TW with the netname FET, aligning with the operator's identity.
  • The address inventory is finely subdivided into numerous /18, /19, and /20 blocks, consistent with a large-scale consumer mobile and broadband estate.
  • Some prefixes, such as 222.157.0.0/18, show different netnames like CCTV-HT-AP or ETWEBS-TW, suggesting historical allocations or specific service segments within the broader network.

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: 432 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.
