About this ASN.

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

AS1535 is an autonomous system whose registered organization is Unknown; the combined Route Views observation recorded zero IPv4 prefixes, zero IPv6 prefixes, and zero observed AS_PATH neighbours at 2026-11-06 20:00 UTC. The observation combines route-views2 and route-views6 data. It does not establish that the ASN is dormant, inactive, or unused outside that snapshot.

IANA identifies AS1535 within resource range 1-1876 as assigned by ARIN. This identifies the allocating regional registry, not an individual assignment record or operator. The supplied evidence does not identify an organization, country, network type, website, or documented products or history for this ASN.

For identification, compare the ASN and timestamp with routing data from other times and collectors, then seek an authoritative organization record explicitly connecting an operator to AS1535. If investigating a particular IP address, check its observed prefix and origin ASN at the relevant time; these zero counts alone cannot identify who used an address or establish security or legitimacy.

Observed routing
