IP / ASN Lookup

Online IP and ASN lookup

IP, CIDR or ASN: PTR/FCrDNS, origin ASN, RDAP, prefixes, RPKI and abuse contacts. Geo hints from registry data only — no false precision.

Data reflects Runstack’s network view and may be stale. Registry allocation (RDAP) is not the same as a BGP announcement.
