Whois Parser Properties & Methods

Each WHOIS parser exposes a defined set of WHOIS properties and WHOIS methods, in addition to the standard object methods and attributes.

WHOIS methods and properties are useful to access the content of a WHOIS response like an object. For example, if you want to extract the expiration date from the following response

*********************************************************************
* Please note that the following result could be a subgroup of      *
* the data contained in the database.                               *
*                                                                   *

just use the #created_at property. For further details about Whois::Record and Whois::Record::Parser property usage, please visit the “Whois Parser chapter”:/manual/parser/.

Here’s the full WHOIS property and method list with the corresponding returned value.

The availability of a specific property strictly depends on the information contained in the registry database.

Properties

WHOIS properties are attributes of the WHOIS response. The parser simply attempts to extract them from the content of the response, apply some basic transformations such as trimming additional spaces or converting the value into an object, and returns the value as it is.

Property Returns
disclaimer String / Nil
domain String / Nil
domain_id String / Nil
status String / Nil
registered? Boolean
available? Boolean
created_on Time / Nil
updated_on Time / Nil
expires_on Time / Nil
registrar Whois::Record::Registrar / Nil
registrant_contacts Array<Whois::Record::Contact>
admin_contacts Array<Whois::Record::Contact>
technical_contacts Array<Whois::Record::Contact>
nameservers Array<Whois::Record::Nameserver>

Methods

WHOIS methods are a little bit more complex that properties because they parse the content of the WHOIS response to return an elaborated information.

For instance, the method #changed? attempts to guess if the current WHOIS response changed compared to an other WHOIS response passed as parameter.

Method Returns
changed? Boolean
unchanged? Boolean
contacts Array<Whois::Record::Contact>
