There is a big DNS server (plus 12 mirrors) on the Internet which lists the servers serving every .com domain (this is the lines of text you pay for when you "buy" a domain name): burningclown.com. IN NS NS2.WESTHOST.NET burningclown.com. IN NS NS.WESTHOST.NET Any names ending in burningclown.com are then listed in the DNS file at ns2.westhost.net and its one mirror: www.burningclown.com IN MX 10 mail.burningclown.com www.burningclown.com IN A xxx.xx.xxx.xxx burningclown.com IN NS ns.host4u.net burningclown.com IN NS ns2.host4u.net mail.burningclown.com IN A xxx.xx.xxx.xxx pear.burningclown.com IN A 111.222.111.222 etc. The IP addresses on the right could be anywhere at any ISP, but Westhost may have a policy of charging extra for IP addresses elsewhere. In your resolv.conf the DNS server you list should be the one closest to your own computer, i.e. the one at your DSL provider or one running on your own computer. This is just to save bandwidth all around. ANY normal DNS server on the internet (e.g. the one at speakeasy) acts as a proxy which finds the right server for any question and caches the result for the time specified in the DNS file from which the result originally came (e.g. the file at westhost for lookups in your domain). In your resolv.conf the search line should list the domain you want associated with the real name of your own computer first, then any other domains you want to search implicitly when you don't type anything. It does the same for DNS names that the regular PATH variable does for program names. > ... have I essentially muddied the situation by having a DSL provider and > a separate host-er? not at all, here is another example: www.us.debian.org is at some US ISP www.dk.debian.org is at some Danish ISP www.jp.debian.org is at some Japanese ISP etc. But they are all listed in the same DNS configuration file which is stored (for maximum uptime) at 4 DNS servers in 4 countries using 4 different ISPs. Cheers P.S. I got the data for burningclown by simply running nslookup on my own computer, DNS is a way of publishing information. -- This message is hastily written, please ignore any unpleasant wordings, do not consider it a binding commitment, even if its phrasing may indicate so.
