AS1635
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- Combined Route Views observation from route-views2 and route-views6 at 2026-11-06T20:00:00.000Z recorded zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero AS_PATH neighbours; absence from this snapshot does not establish inactivity.
About this ASN.
AS1635 is an ASN whose operator and registered organization are unknown here; a combined Route Views snapshot observed no IPv4 or IPv6 prefixes for it. This is a snapshot-based routing result, not proof that the ASN is inactive or unassigned. IANA identifies AS1635 as within resource block 1–1876, assigned by ARIN, which identifies the allocating RIR but does not establish an individual assignment record.
At 2026-11-06 20:00 UTC, the combined observation across route-views2 and route-views6 contained zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. No neighbours were sampled. These counts describe the joint observation across the two named collectors; they do not establish traffic levels, ownership, commercial relationships, or security status.
For identification, compare the ASN with a dated registry record and additional routing observations before associating it with an organization or deployment. If investigating a specific address or route, check its current origin and route history directly: this snapshot alone cannot attribute an address, explain why the ASN was not observed, or support a reputation or safety judgment.
