  6. Issues • No clear purposes defined for registrant, admin, and tech contacts • Often default to be the same person • Registrars and registrants handle them in different ways • Often confusion between individual registering the name, and the legal holder of the name (could be the employer of the individual)

  7. Data access technologies • WHOIS protocol (port-43 WHOIS) • Send some ASCII text and get some ASCII text back • Usually used to provide exact match lookup • Interactive Web page • Wide range of implements by registries and registrars • Usually only exact match lookup • File Transfer • For bulk access • subject to a user entering into a legal agreement (bulk access agreement)

  8. Data Displayed • Domain details (name, nameservers) • Creation date and time • Expiry date and time • Status (optional) • Registrar (optional) • Last update date and time (optional) • Last transfer date and time (optional)

  9. Data displayed • Registrant data • name and address • Admin and tech • (name, address, phone, fax, email)

  10. Problems • Port-43 WHOIS and interactive WHOIS used anonymously for data mining to collect large quantities of contact information • Non-standard approaches used by registrars to limit this • Registrants not clear on purpose for data collected and how data users are given access to this data • Concerns about accuracy and privacy of data • Authorisation problems (who has authority to change domain name record, and who is responsible for the use of the name)
