Dynamic DNS

2024/01/26

I recently upgraded my home broadband, however in the process I lost my static IP address. I have requested a new one, but in the meantime I wrote a program to dynamically update my DNS records in case my router restarts and my WAN IP address changes.

I didn’t really want to change providers in order to move to a proper dynamic DNS setup, since this is a temporary solution, but I did enjoy writing a little code to make it work with my current DNS provider (digital ocean). I appreciate how useful it is to have an HTTP client in the zig standard library!

New broadband is now fibre to the premises, and it’s quite a lot quicker.
