Summary

Alaska Communications (ACS)

United States · AI-generated

isp legacy

ALSK-7782 is Alaska Communications Systems (ACS), the incumbent local exchange carrier for much of Alaska, headquartered in Anchorage.

What it's used for

  • Consumer and business broadband across Anchorage, Fairbanks, Juneau and the Kenai Peninsula, plus enterprise and government connectivity statewide.
  • Reverse DNS across the announced space is dominated by ACS subscriber patterns: IP-ADDR.static.acsalaska.net, IP-ADDR.dynamic.acsalaska.net and IP-ADDR.dynamic.lte.acsalaska.net — the last reflecting the fibre-fed fixed wireless service ACS has been deploying to homes and businesses.

Notable

  • This is a genuine eyeball network, unlike AS7774, whose ALASKA handle belongs to the state university system.
  • Alongside subscriber pools, the space carries Alaskan public-sector customers (municipal and library rDNS appears inside ACS prefixes), so not every host here is residential.

Interesting

  • ACS is majority-owned by ATN International, with co-investors holding the rest. Its build is heavily subsidised by federal universal-service programmes, which is what makes broadband economics work across Alaska's distances.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
