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.
