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.

I think the default solution for this is to use a dynamic dns. There are services for that or you can get yourself a domain and configure that as dnydns in your router. That is what I am doing atleast

https://www.duckdns.org/

Duck it!

Either use a dynamic DNS service, as many others have mentioned and probably easiest, or, assuming you only want yourself to have access to the services, another option is to use something like Tailscale or a WireGuard/FRP instance in a static VPS as the rendezvous point.

I was flat out rejected by my ISP to have a static IP, though I only had it changed once since I started hosting services, so ahatever.

I use tailscale instead of caring about my public IP or dynamic DNS

Bruh mate.
Mine changes daily so stop complaining that hard xD

Honest suggestion: Just set up a dyndns with any dns provider that supports automations.

Proxy through a VPS, or use dynamic DNS if you don't mind occasionally waiting for TTL expiration when your address suddenly changes. You can set it to 1 minute and that often works these days (it didn't always).

Will your ISP give you a static IPv6 block? It's v4 that's scarce, but if it's just for your own stuff and you aren't worried about users on old v4-only networks, it's fine to just use pure v6.

If you want a super cheap VPS with static ipv6 and NAT v4, try tierhive.com.

I pay $5/mo for a VPS and host Nginx Proxy Manager on it

I solved it with a cheap VPS running Caddy as a reverse proxy and a Tailscale connection back to my home server.

I think Tailscale has a service called Tailscale Serve which may work around a frequently changing ip as well. Not sure though as I haven't looked into it much.

Dynamic dns is what you need. Only takes a few minutes to set up

I run pfsense with dyndns and a short TTL. It updates my DNS provider instantly when the gateway IP changes. For mail I got a cheap vps running pfsense again, tunneling back home via Wireguard and haproxy to link up connections. It is very stable and not as hard to set up as it sounds (and cheap).

I use duckdns.org and then make use of CNAME records pointed at the duckdns record for my own domain name/subdomains.

My router (unifi device) keeps duck DNS up to date with my changing IP, but there's lots of ways to get that done.

You could consider tailnet or similar as well?

Dynamic dns. Use it.

I use afraid.org.

Another option would be to just use tailscale.

But if you want unlimited tailscale you will have to host that too and also dynamic dns. Important note, idk what firewall you have, I have a UDM Pro, so that updates my dynamic dns automatically, yours may have something similar.

Do you need to publicly expose your services?

I personally use a VPS with Wireguard

That is a bit crazy if you are in the US. There is no ‘business Id’ just say you are a sole proprietorship, meaning the business is just you, no corporation structure or anything like that and you are dba, doing business as, and your name.

That is how you technically describe yourself when you are a business when you are a person.

Your tax id number would just be your social security number.

It’s legal to transact business as a person.

If you have a domain on cloudflare you can make it point to your public ip using something like this https://github.com/timothymiller/cloudflare-ddns

Also some routers, like tp-link, have a ddns feature where they provide you a domain that points to your public ip

Since nobody mentioned, I recommend https://desec.io/ as the DNS provider. Has a good REST API to update records, also provides a dedyn.io dynamic domain, and runs as a nonprofit. I think ddclient will also support it natively in the next release as well.

The solution of renting a VPS also works but usually incurs some cost. You might also want to look into Cloudflare Tunnels

Man. At least one isp in my area gives you the business plan if you just ask for it. I mean you need to give a business name but you can make it anything you like.

I use a terraform script that pushes my IP up to route 53 every hour. been good enough for me for the last six years.

I have a VPS running nginx and wireguard. I just forward whatever subdomains to my home server over wireguard.

Prior to me having my static IP I used duckDNS and a cron script on a pi. My ISP offers two free static IPs so I got those now. Sorry to hear you don’t even have one.

If you're able to do away with ISP routers with ISP restrictions I highly recommend doing so - hint OpenWRT. Otherwise, Duckdns with cron is your friend:

Or

Duckdns.org and then set up a cron to update it regularly

Thats crazy that you now need to prove you have a business to get that service? Don't worry, it cost way more anyway and offers very little extra to be worth it at least in the US. I used to use duckdns years ago, and now I just said screw it and purchased a domain name from namecheap for a few bucks for the year and a few more bucks for the ssl cert then use the ddns service through them and link it to a pc on my network using the small app they provide to keep the IP updated. I use the name for all my services. Sometimes the name will cost way more when renewing in which case ill just pick another one because screw them. Ive used a .co and now using a .space.

Last time I had to do something like that I used no-ip running on my raspberry pi that's already running pihole

Ddns as others said or use cloudflare dns with cloudflare tunnel

It's been very long since I've had to mess with this, I don't even know which machine it runs on. But somewhere, I have a Cron job that runs a curl to namecheap with a magic string. That magic string confirms I am the owner of that domain and namecheap will automatically update the IP address for that URL to whatever IP address my curl came from.

afraid.org for dns and they have a dead simple way to keep it up to date. I have it running at work in a crontab that sends the current IP every thirty minutes. The site looks old because it is but it functions great.
