Server Implementations

RDAP servers come in two basic flavors, authoritative server and redirect servers. Authoritative servers contain the information for domain names, IP addresses and ASNs, whereas redirect servers issue HTTP level redirects to clients to assist them to get to the right authoritative server. Sometime, as in the case of the RIRs, servers can be both authoritative for their own information and issue redirects for other information.

Listed under server implementations are conformance tools, which are actually clients developed to make sure servers conform to standards. They are listed here because they are of little use to the general-public and typically only used by server operators.
