Cloudflare DNS (APNIC)

GEThttps://api.deepinfo.com/v1/lookup/ip-whois

IP WHOIS of 1.1.1.1 (APNIC): announced by Cloudflare (AS13335) but registered to APNIC Research and Development.

Param: ip
Value: 1.1.1.1

Asks for the IP WHOIS record of 1.1.1.1, the Cloudflare public resolver.

The routing and the registration tell two stories: asn 13335 belongs to Cloudflare, while the network APNIC-LABS (1.1.1.0/24, ASSIGNED PORTABLE, country AU) is registered to APNIC Research and Development, as its remarks explain ("APNIC and Cloudflare DNS Resolver project"). APNIC networks have no handle format like ARIN's: handle is the address range 1.1.1.0 - 1.1.1.255.
