About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1645 is an ASN whose organization, operator, country, and network role are Unknown from the supplied evidence. In the combined Route Views observation at 2026-11-06 20:00 UTC, route-views2 and route-views6 showed zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero AS_PATH neighbors for this ASN. This describes that snapshot only; it does not establish that the ASN is dormant or inactive.

IANA places AS1645 in resource block 1–1876, described as assigned by ARIN. This identifies the allocating RIR for the block; it does not provide an individual assignment record or establish who operates AS1645. No first-party organization, product, history, or website evidence was supplied, so those identity details remain Unknown.

For identification, compare the ASN with authoritative registry records and first-party material that explicitly links the organization to AS1645. For routing triage, check later observations from multiple collectors and inspect any announcement's origin and path before attributing it. The empty neighbor sample means no AS_PATH adjacency was observed in this combined snapshot; it does not establish commercial peering, upstreams, legitimacy, or security status.

Identity
Organization, operator, country, and network type are Unknown from supplied evidence.
Triage
Treat these counts as a time-bounded observation; corroborate any later announcement with registry and first-party evidence.
