14 The thin model sort of works like DNS, except everything is unstructured
15 and totally made-up on the server side and guessed-at on the client
16 side. The clients are trying to parse the unstructured output, like you
17 would if you were trying to screen scrape a webpage. As of ten seconds
18 ago, this is what I get for a lookup of orlitzky.com:
19
20 Domain Name: ORLITZKY.COM
21 Registrar: GANDI SAS
22 Whois Server: whois.gandi.net
23 Referral URL: http://www.gandi.net
24 ...

26 The "Whois Server:" for the domain is something like an NS record, where
27 the guy higher up points you at the next level down. If the whois server
28 for the domain changed, you wouldn't need to update the client -- you
29 could just ask the top-level server for it again. What *would* make you
30 update the client is if, say, that top-level server started outputting a
31 space between "Server" and ":".
