About WHOIS
With the new shared
registration system model, the nature of the WHOIS
server has changed. Traditionally, the InterNIC
maintained the WHOIS server for .com, .net and
.org domain names, and a single query returned
full whois data including, registrant,
administrative contact, billing contact, technical
contact, and nameserver information.
The Old Way:
A single query returned full whois data.
The New Way:
In the multi-registrar model, each registrar
maintains a WHOIS server containing contact and
nameserver information for domains registered with
them. The InterNIC maintains a central, registry
WHOIS server, which simply contains nameserver and
registrar information for all .com, .net and .org
domains.
To find out the registrar of record for a domain,
consult the registry WHOIS server, at:
http://www.internic.net/whois.html
The output from the registry WHOIS query will
indicate the website address and WHOIS server
address for domain's registrar of record, where
full contact information can be found.
Key Points:
Only the WHOIS server of a domains' registrar of
record can be considered authoritative
Some Registrar's configure their WHOIS server to
perform a 'registry lookup' for other Registrar's
domain names; some will even go so far as to
perform a lookup on another registrar's WHOIS
server. However, the only sure way to check domain
availability or get contact and expiry information
is to perform a WHOIS query with the domain's
registrar of record. As a convenience, the OpenSRS
WHOIS server is configured to check other
Registrars' WHOIS databases.
Many WHOIS databases are not updated in realtime,
so that you can make a change to record, but the
change will not appear in the WHOIS output until
sometime the next day. OpenSRS's WHOIS server is
updated in realtime for all domains that we are
the registrar for.
