Hi! I have a computer running ISPConfig with public static ip-address. Also, I have a small intranet with one web server with dynamic ip-address. I'd like to make server with dynamic ip address as a subdomain on the computer with public ip-address, so a dynamic dns. I understand that I will have to make program which will update ip-address when it's changed but my question is, what exactly do I need update? Is it enough to add A record to /etc/bind/pri.<domain> file after the ;;;; MAKE MANUAL ENTRIES BELOW THIS LINE! ;;;; line and then update that line when ip-address is changed? Is there something else that needs to be updated? This subdomain doesn't have to be visible in ISPConfig control panel in dns manager.
