Summary

WCTA

United States of America · AI-generated

residential fiber cooperative access

WCTA is operated by West Central Telephone Assn.

What it's used for

  • The address space carries residential fiber access, evidenced by reverse DNS entries such as ipoe-135-255.wcta.net and ipoe-19-255.wcta.net.
  • The network announces 7168 IPv4 addresses across 3 prefixes with only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, identified as West Central Telephone Assn with netnames WCTA, WCTA-2, and WCTA-3.
  • The address inventory consists of three distinct IPv4 blocks: 216.189.128.0/20, 64.110.16.0/21, and 108.163.68.0/22.
  • Secondary sources confirm the operator is a member-owned cooperative providing 100% buried fiber-optic internet services.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 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.
