Automatically updating a name server has nothing to do with your IP address being dynamic.

In any case, anytime my IP changes, I've noticed the WAN IPv4 is set to 0.0.0.0 in the router config, meaning I have to unplug the modem/restart it in order for it to update to the new IP.

I assume having DDNS would detect this change and automatically update it

DDNS will not restart your modem for you or renew your IP. DDNS will update a name server WHEN you have your new IP. By the looks of it your modem can't handle the IP change so DDNS will not solve anything.

TL;DR: Your modem suck.

>DDNS will not restart your modem for you or renew your IP
I know it's not going to restart my modem. The entire point of this is to set it so DDNS points to the right static host therefore eliminating the need to reboot anything.

>DDNS will update a name server WHEN you have your new IP
That's exactly what I want it to do.

> By the looks of it your modem can't handle the IP change
I highly doubt it's related to the modem.

It's an Aris Surfboard SB8200. I had the same issue with NetGear's CM1000

Okay

I've always powered off everything(modem and router) to have a clean start. I don't know if it's actually necessary for the modem specifically to be turned off.

Sounds like you have to look into your problem a bit more. You're still guessing. Can't fix a problem that way.

Sounds like you don't understand basic networking and the difference between LAN and WAN networks. Don't post shit you read online just because you think it works.

This is for your own good OP.

Of course it's an educated guess. There's no other good explanation for why it happens.

I know how it works.
I already set up the DDNS and it's working as it should. Only way to know for certain it's working since when my dynamic IP changes.

Thanks for the incredibly unhelpful /pol/ response though. Maybe don't post pointless fucking comments.
