ISP won't set up static IP - Services keep going down (lemmy.dbzer0.com)

I called my ISP today to set up a static IP because my services keep being taken down from my IP changing. I either need a business plan or a 5-10gbps residential plan to do that...

I cannot get on the business plan without a valid Business ID so that's not an option. And no way in hell I'm paying for those speeds.

Anyone have any alternatives to stop this from happening so often? My public IP seems to change regularly every 2-3 weeks and it's getting pretty frustrating having to reconfigure things. I only have 2 ISPs in my area and they are both terrible. I assume I'm out of luck, but maybe there's some tech magic I'm unaware of.

I use ddclient with cloudflare as my domains nameserver.

Never had a static ip, but I've never had an issue with it changing because I've always used this.

    Ok great, this sounds exactly like what I'm looking for. Have seen the term DDNS used before but didn't know it was for this. Thanks!

    If your domain registrar doesn't do DDNS, and you don't want to pay extra for one that does, you can get free DNS for life at Hurricane Electric:

    https://dns.he.net/

    All you need to do is finish their little online IPv6 course. TBH the "course" is just setting up your own server properly and proving it.

    It's one of the features I love about Njalla for domains the most.

    You don't even need a ddns service because they support updating through simple https calls.

    So I have a super tiny script that basically checks the WAN IP through ipify, then checks that against the routers current WAN IP, and if they match it does nothing and ends, but if its different, it sends out a curl with the new IP. I have it running every few minutes in a cronjob. It's actually technically my service with the most uptime according to healthchecks.io.
