Such a mechanism has been in place for a while. The domains under .ch have been using it since December 1998. $ whois -h whois.ripe.net '-r -R -T domain ch' [...] domain: ch [...] refer: SIMPLE whois.nic.ch changed: gottsponer@switch.ch 19981223 In the meantime there has been an improved version of the referral mechanism which provides the IP address (or hostname?) of the original requestor to the delegated Whois server, which can be useful for logging/rate limiting purposes. It's certainly documented somewhere on the RIPE Web server. -- Simon Leinen simon@babar.switch.ch SWITCH http://www.switch.ch/misc/leinen/ Who is General Failure & why's he reading my disk?

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).
