Selfhosted

You might want to try out Tailscale. It's a mesh network overlay that you can either share easily within your tailnet or out to the greater internet with funnel (sorta like cloudflare tunnels, but somewhat better at respecting privacy). It's also possible to self host the controller, so you don't have to depend on a third party.

Could you use dynamic DNS? Pretty sure there are some free options.

Nobody else mentioned DuckDNS. It’s free and has worked great for me for years.

You’ll need to install a client that syncs/auto-updates your public IP, then pretty much never touch it again.

What you’re looking for is called Dynamic DNS. I use Cloudflare for my DNS (which feels a little like making a deal with the devil) and Cloudflare-DDNS to automatically update my DNS records when my WAN IP changes. Basically, the container checks the current WAN IP, checks the current Cloudflare DNS records, and pushes a change if they don’t match. It runs every few minutes, and then rests again until the next check. I’m sure other DNS providers have similar ways to set up DDNS.

It’s not a 100% foolproof thing, because your WAN IP changing will take a few minutes to update. But a few minutes of downtime is much better IMO, when the alternative is needing to manually VPN into my server (if the VPN even still works, since the WAN IP changed), and troubleshoot it every time the IP address changes.

Our setup uses a domain pointed at a dynamic (but stable) IP with a script to update it periodically

I've had a domain with a dynamic up for over a year with no problems. I have a simple script that runs every 30mins to check if my IP has changed, then updates the DNS records when required.

Sure, you can just use your home wifi. Some of them are static, and others don't change really often, like once a month, so dyndns will work well. You could also use cloudflared that is a proxy you can use even if you can't open your ports

I have the VPS setup, and it's not bad at all, I pay 3.99 a month and it acts as a gateway into my network filtering any malicious ip by using crowdsec.

I use Pangolin reverse proxy, but you can also use netbird.

I prefer this because on top of the routing options it ads extra security and lets me share subdomains with friends and family without exposing my network to the internet

It is very much possible to have a dynamic IP and a usable domain.

Both Cloudflare and desec.io (for example) have APIs that you can hit everytime your public IP changes.

I have a script that checks every minute whether my public IP has changed from the last check, and if it has, an API call will be sent.

With a scheme like this, your downtime will be minimal, if ever even noticed.

I run a variety of self hosted things via my domain on a dynamic IP. I just have dynamic dns set up to check my current public IP periodically, and update the dns entry if it changes.

VPS with a public ip (which just takes all the fun out of selfhosting)

Why do you say this? My VPS only runs a reverse proxy and WireGuard, with all services hosted on my computers at home.

My ISP changes IP somewhere around once a month. I own a domain on porkbun and they offer a simple docker compose script that updates my records to a current IP.

I believe other domain selling platforms also have similar scripts or solutions.

I use this, Cloudflare zero trust. I run a connector (tunnel) named cloudflared on a raspberry pi which connects to cloudflare. The zerotrust tunnel configuration (in CF dashboard) lets me route http traffic into my local network by domain. The Application access policy in zero trust lets me secure it.

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

If you already have a domain name and don't want to switch to something else, know that some DNS registrar have an API to handle the domains. For a short period of time I had to rely on this and had a little python script to get my current IP and apply it to every A record in my DNS zone.
It worked well (but then I ~~took an arrow in the knee~~ had static IP)

I believe cloudflare has some sort of tunneling option but I've never really looked into it, it might get around that.

I've been self hosting for 20 years with the same domain(s) and have never owned a static IP. Use a reliable DNS service with simple update tools (curl on a cron job for example).

My dynamic IP almost never changes. I’ve had 3 in the last 10 years. How often does yours change?

There’s also dynamic dns if yours changes often.

You can use Netbird Cloud's reverseproxy to point your domain to a device on your wireguard mesh.

That way your home server can be under 3x NATs and dynamic IP and you'll still be fine.

Later if you want to own the netbird you can self host it on a VPS if you're willing to migrate all devices to your self hosted wireguard mesh.

You need static IP only if you want to host the autoritative DNS server for your domain (spoiler alert: you don’t).

You don’t need to proxy your traffic via VPS (higher latency for no good reason) and the dyndns providers are over priced.

What you need is:

• Buy your domain
• Use a free DNS provider (I used for years the excellent dns.he.net but it is a bit cumbersome. Nowadays I gave up and I now use cloudflare without any proxying, just pure DNS)
• Point your registrar to the dns provider
• use ddclient to update the IP of a domain entry (e.g. server.example.com)
• add as many CNAME as you want that point to that entry (so you can have stuff like Jellyfin.example.com www.example.com Nextcloud.example.com)

That’s all… ddclient will update that single dns entry every time your server restarts (or the IP lease expires and you get a new IP)

The only thing you need to pay here is the domain (you can get free domains but that is another story and tbh I would not recommend, there are cheap domains out of there)

I use OVH for all things DNS, TIL: they have a dynhost thing that will do all the DNS updating for you!

What are you asking? You can just buy a domain whenever you want. You can use it on your server without a VPS or static IP.

Are you asking us how to make your services reachable at that domain publicly over the internet?

My dynamic IP rarely changes. When it does, it gets updated by a Docker favonia/cloudflare-ddns image. I have yet to notice downtime.

The VPS I rent from Ionos for tunneling is $2 a month just so you know it’s not a major amount of money.

You don't have any great options but you do have some options. You'll need dynamic DNS, which you can get for free by various providers. This will manage a "dynamic" DNS entry for your occasionally changing, non-static IP at home. The dynamic DNS entry won't be on your own domain name, it will be on the provider's domain name. But wait! That's just step one.

You can still get your own, fully-functional domain name, and you can have all the domains and subdomains you want, and set them up however you want, with one important restriction: You can't use IP addresses (because yours is dynamic, and changes all the time and you would have to be constantly updating your domain every time it does, and there would be delays and downtime while everything gets updated).

Instead, your personal domains have to use CNAME records. This substitutes the IP from a different domain INTO your domain. So you CNAME every entry on your own fancy domains to point at your dynamic DNS provider, which manages the dynamic part of the problem for you and always gives the real IP you need. Nobody sees the dynamic DNS name, it's there, but it's happening behind the scenes, they still see your fancy personalized domain names.

It's still not going to be perfect, it won't work well or at all for certain services like email hosting (self-hosting this is not for the faint of heart anyway) that are very strict about how their DNS and IP addresses need to be set up, but it will likely be good enough for 99% of the stuff you want to self-host.

DynDNS is your friend.

I'm late to the party, but could everyone answer me this- how often does you're public IP actually change with any of your ISPs??

With the numerous companies I've used, the ONLY time I've ever seen my IP change is getting a new modem through, say, Comcast or whoever. It goes by MAC address, and if you use Comcast and then set to bridge mode and use your own device, that's a new MAC so you'd get a new public IP. Swap ISPs obviously a new IP.

I've NEVER randomly received a new IP when using the same equipment consistently, so I'm not sure why everyone's so worried about dynamic DNS stuff.. Maybe outside the US is different? I've lived in a few States and it's always the same. If you make a hardware change, just note you should also double check your IP and update it, that's all.

Yes it's possible. You can buy a domain name and then do literally nothing else if you want.

If it's just for LAN use, you don't even need to buy a domain name. You can use anything under the home.arpa, test, or internal TLDs. https://en.wikipedia.org/wiki/Special-use_domain_name

i have a little program for dynamic dns running in docker that checks every few seconds for an IP change and swaps my DNS records if it gets rerolled.

works well on my home network, I can use my domain for all my private services local and remote through wireguard :)

You do not need a static IP address or dynamic DNS if your domain registrar provides a REST API. My current registrar is Porkbun and they have a REST API. I simply have a cron job that regularly checks if my public IP[^1] differs from the domain's A-record. If it does, it updates the record to match the public IP address using their API.

[^1]: I use Porkbun's ping endpoint to obtain my public IP. There are also alternatives such as Ipify.

I have dynamic dns address and a handful of CNAME records on my domains pointing on that dyndns-address so I can use 'proper' names with my services. When my public IP changes it takes a few minutes for the records to update, but it usually happens only when my router reboots so it's been good enough for me.

Also I use two separate dyndns providers so there's likely at least one working DNS entry to my network.

If your home IP does not change often, you can use a dynamic DNS service. But your services will be unavailable from the time that your IP changes and the time the DNS record is updated and the cached responses expire.

It is possible to use a dynamic DNS service. They're typically pretty cheap. I did for several years. It kind of sucked so I rented a VPS.
