I am running a web site on a dedicate server at IP 18.104.22.168. The DNS is configured like so:
* A 22.214.171.124 @ A 126.96.36.199 @ MX 10 mail.mydomain.co.uk ftpes CNAME mydomain.co.uk. staff A 188.8.131.52 www CNAME mydomain.co.uk. mail CNAME mydomain.co.uk.
However, I need have a temporary duplicate of this site (hosted on a different IP) for testing purposes, but accessible via a subdomain. Normally to achieve this I would add this record:
test CNAME 184.108.40.206
However, in this case the duplicate site is hosted on an Azure VM, and is not permanently live. Therefore, the IP changes each time the VM is brought online.
I've been looking at dynamic DNS services, but can't find enough information to answer the question, which is, is it possible to point a subdomain at a dynamic service which then handles the real (changing IP) automatically. Perhaps something like this...
test CNAME dynamicIpProvider.org
I'd prefer not to have to migrate all the DNS settings to the dynamic provider if possible, and also not to have to set up a new domain name.
