This feature was introduced in 2.3.2 software release. Please find below
the extract from the Release Notes:
NEW FEATURES
- New type of referral: CLIENTADDRESS
o A fourth kind of referral is defined, CLIENTADDRESS (The other
three were RIPE, INTERNIC and SIMPLE).
o The IP address of the client is sent to the referred whois
server, if the referral type is CLIENTADDRESS.
o The IP address is sent using the -V flag. The version and the
IP
address will be separated by a comma (eg,
-Vripe2.3.1,193.140.45.45).
o No other flag will be forwarded to the referred whois server.
o When the server gets such a request, it checks the IP number
of
the server which does the referral against a list of
authorized whois
servers. If it is not in the list, it will be rejected.
The list is named AUTHORIZEDFORREFERRAL in the configuration.
o Then, the IP address of the client is extracted from the -V
flag
string and it will be regarded as if it is the IP address of a
directly querying whois client (ie, it is checked against the
list of
DENYWHOISACCESS list).
