About this ASN.

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

AS1525 is assigned by ARIN in the IANA AS-number registry; its operator and purpose are Unknown from the supplied evidence. In the combined Route Views observation at 2026-11-03 14:00 UTC, across route-views2 and route-views6, no IPv4 or IPv6 prefixes, addresses, or AS_PATH neighbours were observed. This snapshot does not establish whether the ASN is currently active elsewhere.

The IANA record places AS1525 in resource block 1–1876 and describes it as assigned by ARIN. That identifies the allocating RIR only; it does not establish an individual assignment, organization, location, or deployment. No first-party operator, product, or history evidence is supplied, so those details remain Unknown.

For identification, compare the ASN against the relevant organization’s own network documentation or registry records, then check additional routing observations over time and from other collectors. Treat any later announcement as evidence of visibility at that observation time, and verify the announcing network with first-party documentation before associating it with an operator. The empty neighbour sample provides no basis for inferring upstreams or commercial relationships.

Identity
