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).
