Summary

Farmers Telephone Cooperative

United States of America · AI-generated

residential telecom cooperative dsl

The AS handle FTC-INET is operated by Farmers Telephone Cooperative, Inc.

What it's used for

  • The address space carries residential DSL access, evidenced by reverse DNS entries such as dsl-254.pool3.6.e120.sumt.ftc-i.net and dsl-254.pool4.18.e120.sumt.ftc-i.net.
  • The network announces 57344 IPv4 addresses across 31 prefixes and 1 IPv6 prefix, with only 4 observed neighbours, indicating a local access provider rather than a transit hub.

Notable

  • All registrants in the RDAP data are consistent with the announcer, listing Farmers Telephone Cooperative, Inc. with netnames FTC-INET and FTEL.
  • The address inventory is finely subdivided into numerous /20, /21, /22, and /23 blocks, reflecting site-by-site segmentation typical of a regional utility.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
