Summary
Connect Northwest Internet Services, LLC
legacy
Registered to Connect Northwest Internet Services, a Seattle-area fibre ISP. What the ASN actually announces is not that network: most of its address space is registered to third parties associated with commercial residential-proxy operations. This card describes the discrepancy and deliberately assigns no kind.
What it's used for
The holder's own description is a regional access network: symmetrical fibre to homes and businesses across the Pacific Northwest. That is a real, findable business.
The inventory disagrees. RIS sees 92 announced IPv4 prefixes carrying 35,840 addresses, no IPv6, and one observed neighbour. Almost all of it is small, scattered /22s and /23s drawn from two registries at once, which a Pacific Northwest access network has no reason to announce.
Notable
The decisive question for this shape is not what the prefixes look like but who they are registered to, and here the registrants are not the holder:
79.174.8.0/22is registered ascode200-20190912, and31.132.60.0/22and91.90.80.0/22asCode200-US. Code200 UAB is a Lithuanian company associated with commercial residential-proxy services.94.156.224.0/23is registered asUS_home3— pool naming characteristic of a residential-proxy exit network, not of a subscriber block.2.56.20.0/23,84.39.202.0/23,77.75.52.0/22,139.28.92.0/22,193.31.34.0/23and195.38.2.0/23are registered underDE-ISOMEDIAvariants, a separate entity from the AS holder.- The ARIN-side blocks carry their own unrelated handles (
EGN,EGNL,ADCIL).
Held out of every classifier list. residential is precisely the label a proxy exit network most wants, and it is the label the holder's own marketing invites. The addresses in this AS must not be geolocated to Seattle, and must not be read as consumer broadband: they are third-party space announced under an ISP's AS number.
Interesting
This is the address-broker silhouette with the discriminator actually checked. The scattered multi-registry shape alone proves nothing (plenty of legitimately untidy multinationals look identical). What settles it is that the prefixes are registered to unrelated third parties rather than to the operator, and those third parties are proxy-network entities. Registration plus rDNS, not shape, is what separates a real messy operator from a brokered one.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
