( webmaster@ ... ) for each > DNS is required ... each dns server uses itself to serve web pages I'm a bit mixed up here so let me walk through it. domain name: alwaysup.com SanJose Box (ip 12.13.14.15) SFO Box (ip 18.19.20.21) Each runs DNS. Each has an entry for alwaysup.com in its DNS config files. Each has all the website files for alwaysup.com. alwaysup.com has a typical domain name registrar, and the DNS entries at that registrar for alwaysup.com are 12.13.14.15 and 18.19.20.21 (our two boxes running DNS). So now our website surfer in NY types in alwaysup.com into his/her browser. A typical DNS query for alwaysup.com would return 12.13.14.15, because that box is listed as primary DNS authority. But let's assume the SanJose box (12.13.14.15) is down, so it doesn't answer and the DNS request rolls down to SFO (18.19.20.21). It answers that alwaysup.com is itself and serves up the page. Is this right? Thanks, Kevin --
