some nameserver has it cashed. you will have to wait 'till TTL (time-to-live) expires... (which hopefully you set to a correct value :)

there is nothing amazing about it, it's dns ;)

what nameserver(s) are you using by default? look each of them up for domain.com (use "set q=any" and "domain.com" to get a bit more of information about domain.com). look up your local host and your name server.

did you modify the records recently? if you changed the IP you probably did. did you update the serial number in the SOA record? otherwise ---you will get the old ip from other name servers and the newer ip from your local name server---. to clarify this also lookup some more distant nameservers in order to verify if the will get the newer ip....

there are a lot of things to test. if you'd like to get more out of dns read "DNS and BIND" from O'Reily. It is quite informative.

depends. every named/bind version needs a central configuration file. if you told it to use /etc/named.boot it will use /etc/named.boot, if you told it to use something else, it will use that instead (see -b parameter). anyway: you must have a central configuration file and there you _SHOULD_ remove all things that are no more actual........
