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.

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.

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

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

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

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.

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.

Ddns as others said or use cloudflare dns with cloudflare tunnel

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?

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

Do you need to publicly expose your services?

I personally use a VPS with Wireguard

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

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.

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

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).

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.
