domain handle (networking) Information held by a domain name registrar about a registrant (the person or organisation that owns the name). Typically the registrar stores one copy of this information and refers to that copy for each additional domain registered by the same person. The information would include basic contact details: name, e-mail address, etc. and billing information. Some of this information would be used to populate the whois database entry for a domain.
