Summary
General Communication, Inc. (GCI)
isp residential legacy
GCI is General Communication, Inc., Alaska's largest telecommunications company and by far the dominant broadband provider in the state.
What it's used for
- Consumer and business internet access across Alaska — cable, fibre and fixed wireless. Every sampled prefix resolves under
gci.net, with the classic reversed-octet subscriber pattern (NN-NN-NNN-NN.gci.net) for dynamic addresses and a.static.gci.netsuffix for static assignments. - GCI's own backbone, and the long-haul and satellite links that connect remote Alaskan communities.
Notable
- This is an eyeball network: an IP in AS8047 is almost always a subscriber, and almost always physically in Alaska. Address blocks like
24.237.0.0/16and209.165.128.0/18are registered to GCI directly. - Because GCI covers so much of the state, the AS is effectively a proxy for "consumer internet user in Alaska" — a useful signal, since very few other networks serve that geography at scale.
Interesting
- Serving Alaska means serving places with no road access, so GCI's network leans on undersea fibre, microwave and satellite backhaul to a degree almost no other US broadband operator has to.

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: 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.
