Dynamic IP hostname provider?

[Mark M]

Not sure I have the title correct but I need to access a NAS drive at home that has a dynamic IP (via Sky) but remember seeing something about applying a hostname to the dynamic IP so you can dial in that way if the IP changes?

Hope the above makes sense!

It's the new sky hub which I don't think has it but I was looking through my Synology NAS settings and it looks like you can set it up on there via a free Synology account so going to have a look thanks.
