Hey!

Basically, the title, I called my ISP because I was getting some minor internet interruptions every 12 hours or so, and they told me that that's the way it works with dynamic ips, they restart their services every 12 hours, which leads to a minor disconnection.

My question is, other than requesting a static ip which is very expensive where I live, can I solve this? I did some research and came across something called ddns or mydns, or using pihole, is this correct? Can this be fixed?

Thanks!

You need a new ISP if this is truly what is happening.

Who is the ISP?

DynDNS doesn’t solve the problem.

DDNS acts as a proxy service between the Internet and your home network. It’s a simple way to have a service running at home (like a Minecraft server) and make it always available to users outside of your home. The would go to a website like “rafa.dyndns.com” which would forward their traffic to your home network. The magic is dyndns is changing the route from their domain to your home network without anyone knowing about it.

The ISP cycling your WAN IP lease every 12 hours is unusual and tells me either A) they’re not a sophisticated ISP or B) you live in an area with an unstable backend.

For an example of B, they might be doing infrastructure improvements in your area which means they have to restart the nodes regularly.

Unfortunately for you, there’s not much to do about your home network connection stability if the ISP is restarting the nodes this often.

I’d suggest either finding a new ISP (if possible) or talking to someone else at the ISP (Tier 2 or Tier 3 Support) about why this is happening and if they have a long term solution
