It is very much possible to have a dynamic IP and a usable domain.

Both Cloudflare and desec.io (for example) have APIs that you can hit everytime your public IP changes.

I have a script that checks every minute whether my public IP has changed from the last check, and if it has, an API call will be sent.

With a scheme like this, your downtime will be minimal, if ever even noticed.

Probably nothing has really changed. And I am not claiming it to be a Discord killer, as it really only does the voice rooms well.

But I am recommending it if you and your friends just need a voice room or two (as me and my friends do).

I have tried XMPP, Matrix and now I’ve settled on Mumble.

Me and my fellows mostly just need a voice room or a couple to sit in, and Mumble does that best out of these three, in my opinion.

I recommend giving Mumble a try as it is super easy to set up and use. Users don’t need to even create accounts to join servers.
