AS10557 — CNW

AS10557 announces 73 IPv4 prefixes covering 29,184 addresses and 0 IPv6 prefixes.

About this network

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:

• 79.174.8.0/22 is registered as code200-20190912, and 31.132.60.0/22 and 91.90.80.0/22 as Code200-US. Code200 UAB is a Lithuanian company associated with commercial residential-proxy services.
• 94.156.224.0/23 is registered as UShome3 — 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, 193.31.34.0/23 and 195.38.2.0/23 are registered under DE-ISOMEDIA variants, 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.
