Setting up a subdomain with a different IP address - SOLVED Please excuse what maybe to some a relatively simple request. I run ISPconfg 3 on a Debian server. I maintain a number of separate clients websites and email all on the same IP addresses. One client has asked me to set up a subdomain of supplies.hisdomain.co.uk and point it to a different IP address ( not my own ) using the A record> What is the best method to accomplish this and what commands ( such as dig ) could I use to check it is done. I am asking fo advice as I am not confident playing around with DNS zone files and dont want to mess up the existing set up. All help gratefully received.
