dle
, which in the Internic output is a domain name, and in the nic.fr output is in the
nic-hdl field. Handles are guaranteed to be unique, and are used to get more specific
information about a person or a network. If you search for a handle, you will get at most
one match. If your search only has one match, either because you're lucky or you're
searching for a handle, the server returns a more detailed record. Here's a search for
oreilly.com
. Because there is only one
oreilly.com
in the database, the server returns all
the information it has on this domain:

The whois protocol supports several flags you can use to restrict or expand your search.
For example, if you know you want to search for a person named “Elliott” but you aren't
sure whether he spells his name “Elliot,” “Elliott,” or perhaps even something as unlikely
as “Elliotte,” you would type:
%
whois Person Partial Elliot
This tells the whois server that you want only matches for people (not domains, gate‐
ways, groups, or the like) whose names begin with the letters “Elliot.” Unfortunately,
you need to do a separate search if you want to find someone who spells his name “Eliot.”
The rules for modifying a search are summarized in
Table 8-3
. Each prefix should be
placed before the search string on the command line.
