Domain lookup

This query can be used to look up a single domain by the FQDN in a zone administered by the Registry.

Lookup by IP is not implemented.

The server does not recognize any parameters with this query.

Query path segment

/domain/example.cz

On the top level, the response may contain members:

• entities – an array of entities (linked contacts and the designated registrar), RFC 7483#section-5.1

• events – an array of events that have occurred on the domain, RFC 7483#section-4.5

• fred_keyset – linked keyset (FRED extension), see Keyset lookup for members

• fred_nsset – linked nsset (FRED extension), see Nsset lookup for members

• handle – registry-unique string identifier referencing the domain (domain name), RFC 7483#section-3

• ldhName – textual representation of DNS names, RFC 7483#section-3

• links – navigation to related on-line resources, RFC 7483#section-4.2

• nameservers – an array of nameserver objects, RFC 7483#section-5.2

• notices – information about the service, RFC 7483#section-4.3

• objectClassName – string “domain” representing the object type in RDAP, RFC 7483#section-4.9

• port43 – hostname of Registry WHOIS server, RFC 7483#section-4.7

• rdapConformance – an array of strings, each providing a hint on the used specification, RFC 7483#section-4.1

• secureDNS – secure DNS information, RFC 7483#section-5.3

• status – an array of status flags describing the object state, see Status mapping, RFC 7483#section-4.6 and RFC 8056#section-2

Note

A response may contain an actionEvent called “enum validation expiration”, which is an extension of events in ENUM domains. See specification.

Example of additional event in an ENUM domain
