AS1621

AS1621 is an ASN with no identified operator in the supplied evidence. In a combined routing observation from Route Views’ route-views2 and route-views6 collectors at 2026-11-06 20:00 UTC, it appeared with three IPv4 prefixes and no IPv6 prefixes. This snapshot supports a limited routing description, not a conclusion about who operates the ASN or whether it is active at other times.

The same combined observation estimates 65,536 IPv4 addresses and records two AS_PATH neighbours: AS3356 and AS6461. These are path adjacencies in the observed data; they do not establish verified peering, upstream, customer, or provider relationships. The observation covers both named collectors jointly, not separate counts for each.

For identification, compare the ASN and its announced prefixes against the routing snapshot timestamp and check whether later routing data shows changes. Treat the neighbour values as leads for path review only. The IANA entry places AS1621 in the 1–1876 resource block and identifies ARIN as the assigning RIR; that block-level information does not identify an individual assignee. No operator, country, website, or security characterization is established by the supplied evidence.

Identity

Operator and country are unknown from the supplied evidence.

Routing snapshot

Three IPv4 prefixes and zero IPv6 prefixes were observed jointly across route-views2 and route-views6 at 2026-11-06 20:00 UTC.

Triage

AS_PATH neighbours were AS3356 and AS6461; these observations do not verify commercial relationships or security status.
