Mapping Different DDNSes to Different Computers/Hosts?

and FWIW - a single IP can be actually used with two different DDNS - I have my own domain with DynDNS, and also the same IP is registered with QNAP's DDNS for CloudLink...

map them out to different ports... and update your A, CNAME, and ALIAS records at the DDNS provider - they can walk you thru it.

host1 port 80 ------> your IP port 8080 ----> ddns ------> example.com
host2 port 80 ------> your IP port 8081 ----> ddns ------> example.net

Wow, this just resolved my issue!

Using No-IP's free service, I create the first hostname (e.g. example.ddns.net) with an A record (i.e. IP address) and have Merlin update that in the DDNS menu. This will now point to the router.

Then within Merlin, I set a port forwarding rule pointing an unused port of the router (e.g. 12300) to the required port of the computer connected to the router (e.g. 80).

Finally, back in No-IP, I create the second hostname with a Web Redirect record (e.g. anotherexample.ddns.net) that points to the required computer by using the first hostname and the "unused" port (e.g. example.ddns.net:12300)

Now, when people go to anotherexample.ddns.net, they will be pointed to example.ddns.net:12300 instead, which will then bring them to the required computer.

Note that in the Web Redirect record, you can use an URL. This means that you can even use URLs like example.ddns.net:12300/owncloud.

For other DDNS providers, see if they have similar types of records.

Yeah, I just realised that too, now I do feel real silly

But how do I simultaneously update both or more DDNS services within Asus-Merlin seeing that there is space for only one service provider? Do I do one using Merlin and the others on my computer with the service providers' update clients?

I have a shell script that updates on the backend, behind the router... even though, with my router, pfSense could probably do it all on it's own, but I don't have a need to redo things, as everything works

Hmm... That is a good idea, just that I am not too sure how to go about doing it. Are you using ddclient?
