Dynamic IP for subdomain
I have an ISPConfig 3 server on a VPS at TekTonic. I have a dynamic IP at my house that I would like to point a subdomain of my VPS to, such as athome.mydomain.com.
Is there some way that I can script an A record change for a particular domain? Something like:
My home server visits a page on my VPS>Script on VPS tells ISPConfig IP visit came from>ISPConfig changes record of subdomain to that IP.
