FEG-MPLS is the AS handle for Far EastTone Telecommunication Co., Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as 39-12-16-0.adsl.fetnet.net and 39-12-31-255.adsl.fetnet.net.
  • The AS announces 20480 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.

Notable

  • Both announced prefixes, 39.12.0.0/18 and 39.12.64.0/20, share the netname FEG-MPLS-NETWORK-NET, consistent with the registrant Far EastTone.
  • The address inventory consists of two contiguous IPv4 blocks within the 39.12.0.0/16 range, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
