cooperative residential alaska telecom

ASN-CTCAK-1 is held by Cordova Telecom Cooperative, Incorporated.

What it's used for

  • The address space carries subscriber traffic for a rural telecommunications cooperative, evidenced by reverse DNS entries like 199.189.129.255.ctcak.net and netnames such as CTC-155.
  • The AS announces 2560 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio that indicates an access network serving local subscribers rather than a transit provider.
  • Traffic from this AS consists of residential and business internet, landline, cellular, and VoLTE data services for the Cordova, Alaska area.

Notable

  • Registrants for the majority of prefixes (199.189.128.0/22, 64.38.108.0/23, 207.229.106.0/23) align with the announcer, while 38.58.188.0/23 is registered to Cogent Communications, LLC.
  • The inventory includes a mix of smaller /23 blocks and a larger /22 block, alongside a single /32 IPv6 prefix.

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 1,851 prefixes, as published 2026-11-04. 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.
