I’m using Cloudflare for DNS, and have two TLDs, and I want both of them to be dynamically updated by Home Assistant. However, it seems I can only do one at a time… is there any way around this?
Make one domain a CNAME of the other?
The problem is I have a number of SRV records on both TLDs that point to the same IP… and as far as I can tell you can’t point an SRV to a CNAME record, only an A record - but please correct me if I’m wrong… I’m nowhere near a DNS expert!
It would not be against the DNS definition, but it would be against the SRV definition.
It often work though, but it is an “unsupported” way of doing it.
In this case I would probably move the handling of the second TLDs update to another server. It could just be a small Pi2 or similar.
I do have another server in the house… maybe I’ll have a look at running a script on there that updates the DNS for me when Home Assistant detects a chance
No need to bring HA into the equation.
The script just need to detect a public IP change and do the update of the DNS entry.
