Can multiple dynamic DNS resolve to the same IP address

Question

Can multiple dynamic DNS resolve to the same IP address? I would like to keep some things separate in my home network and wondered if I can use different dynamic DNS addresses to resolve to my home IP?

Can multiple dynamic DNS [addresses] resolve to the same IP address?

Yes.

You can certainly do this, but as suggested by w3dk you will need to differentiate the traffic somehow on your home network. The simplest way to do this is by also using separate ports for each service. If you have some "services" that somehow operate only on one port (e.g. a web server serving two or more separate http:// sites) then you will need to look in to a method of separating out that traffic in another manner (e.g. virtual hosts).

You can certainly have multiple domains/hostnames in DNS that resolve to the same IP address. However, whether you can differentiate this traffic in your home network will depend on the capabilities of your router. Perhaps using different port numbers would be preferable?

Yes, I plan to. One is for openVPN the other a web server. Thank you

With regards to the web server (usually port 80) you can use name based VirtualHosts so you would be able to easily differentiate between different hostnames (multiple websites).
