rightly said xentos...

A record to his naked domain name from his ip or using a sub domain like www to his ip will do the same ...

first point ur naked domain to ur vps ip using A record in dns..

then create another A record using www or anything u wish to ur naked domain name..

eg

urdomain.com -> your ip [A record]

www [or] anything.urdomain.com -> [A record]

put the subdomain.urdomain.com in ur vps host...

create the name servers ..as ns1,ns2.urdomain.com and update ur registar & ur vps provider as well..now ur good to go..
