About this ASN.

Updated  ·  Confidence: Low  ·  3 sources  ·  How this page is checked

AS1690 is an ASN whose operator and registry identity are unknown from the supplied evidence; no IPv4 or IPv6 prefixes were observed in the combined routing snapshot at 2026-11-06 20:00 UTC. The snapshot combines Route Views route-views2 and route-views6 observations. It contains zero observed prefixes, zero estimated IPv4 addresses, zero AS_PATH neighbours, and no sampled neighbours. These results describe that snapshot only; they do not establish that the ASN is inactive or unused at other times.

IANA lists AS1690 within the resource range 1–1876 as assigned by ARIN. This identifies the allocating RIR for the block, not an individual ASN assignment record or current operator. The supplied evidence does not identify an organization, country, network type, website, or documented products or history for AS1690. No operator should be inferred from the ASN number or registry block.

For investigation, compare additional dated routing snapshots and collectors to determine whether announcements appear at other times. If a prefix or neighbour is later observed, inspect its announcement path and corroborate any claimed operator with first-party documentation explicitly connecting that organization to AS1690. Treat routing adjacencies as observed AS_PATH neighbours, not verified commercial peers or upstreams. Do not use this single combined snapshot to conclude inactivity, safety, or legitimacy.

Routing snapshot
Zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC.
Registry
IANA places AS1690 in a block assigned by ARIN; this does not identify the individual ASN's operator.
Triage
Operator identity and activity beyond this snapshot are Unknown; compare additional dated observations and seek first-party attribution.
