github.com/jauderho/rdap (go): Package rdap implements a client for the Registration Data Access Protocol (RDAP).  RDAP is a modern replacement for the text-based WHOIS (port 43) protocol. It provides registration data for domain names/IP addresses/AS numbers, and more, in a structured format.  This client executes RDAP queries and returns the responses as Go values.  Quick usage:  The QueryDomain(), QueryAutnum(), and QueryIP() methods all provide full contact information, and timeout after 30s.  Normal usage:  As of June 2017, all five number registries (AFRINIC, ARIN, APNIC, LANIC, RIPE) run RDAP servers. A small number of TLDs (top level domains) support RDAP so far, listed on https://data.iana.org/rdap/dns.json.  The RDAP protocol uses HTTP, with responses in a JSON format. A bootstrapping mechanism (http://data.iana.org/rdap/) is used to determine the server to query.
