I got a homelab, at the moment I am only running some local stuff and tailscale to reach my stuff remotely.

I can use tailscales ddns, but I would like a real domain. Is there a domain registrator that works with dynamic ips? Or do I need to use a CNAME instead of A record?

    It really depends on the company that you use to manage the domain’s DNS. As long as they have an API to update DNS records…

    For example, I can have my domain at Porkbun and have its DNS managed at Cloudflare. Cloudflare allows updating DNS records via API…so there’s programs to update it. Some routers even support it.

    Worst case, you can set up a service like duckdns and have your domain, via cname, point to the duck DNS subdomain.

    There’s options.

      I think using the cloudflare API is the way to go. You could probably set up an internal service that translates your home router’s dyndns request to a cloudflare API call.

        Only if you had root access to your router. It’s a lot easier to write or find a very simple update script and schedule it to run every now and then via crontab.

          The daemon script is simpler, true. but usually you can just point your router at some dyndns URL and you could put an internal IP for that.

    All domains works with Dynamic IPs - it all depends on what DNS-provider you use :) Provider like Cloudflare ( I do not recommend Cloudflare) and afraid.org both offer dynamic DNS.

        It is a giant MITM proxy, and whoever who has access to their logs have the potential to gain a lot of control

          Don’t have to use their proxy. My gateway router uses cloudflare to set the IP via the API and I just use self-signed certificates. A record resolves to my gateway, not some cloudflare server.

          They also do a lot of work in the privacy space. Encrypted Client Hello to protect SNI came from them.

          If you use any company for TLS termination they can MITM (e.g. AWS certificate manager).

      Yea, that’s right. What I was looking for was like one stop shop. Where I can pay for my domain and dns needs. My current domain registrator does not have dynamic dns, so I have to use a CNAME from another place with a ddns.

        Since your name is Hemlig, I assume you are from the Nordics. Loopia has support for dynamic DNS.

    There are many ways to update dns automatically, I have used this container in the past. You could probably even write a bash script/cron job that checks your IP and updates it with curl depending on your DNS provider.

    If you are already running tailscale you may be interested in using a funnel, which lets you accept and route internet traffic to your tailnet. I don’t use tailscale so can’t comment on how good/bad/useful this is.

    You could also run some sort of service like frp from some remote box (like a VPS in DO/Linode/etc). This or the funnel lets you not expose/advertise your home IP address if that is a consideration.

        I usually use autossh to establish a persistent port tunneling but sometimes got frustrated with the performance of the encrypted tunnel for some use case. Sometimes I don’t need encryption, but need to saturate my nic. frp seems to fit this use case.

        I actually just migrated things to a setup that is pretty neat using FRP: I run frps on 2 Linodes in the same datacenter and have set up IP sharing for failover between them (which is a neat feature Linode, Vultr and probably a few others offer), and then I run 4 frpc’s, two for each frps in case one of them breaks somehow. Lots of redundancy without all that much effort.

    Cloudflare, Porkbun, Namecheap and many other registrars offer dynamic DNS via API or a ddns client very easy to setup.

        using azure ad for user authentication. azure ad is free but i have a paid o365 so i use that to authenticate against for access to my containers that have a fqdn attached/directed to it. and most of the containers/apps have sso with azure ad integration option available so no more logging into each single app/container.

    ZoneEdit.com has a free plan with dynamic DNS for at least one „real“ domain (domain registration not included). It‘s not the most user friendly UI but super powerful. You can pretty much add any DNS record you like.

    Do you want the host to be accessible fully from any host, or do you control all hosts you want to access it?

    For mine, all the devices I want to access my personal host I have setup zerotier, and then pointed cloudflare at my zerotier address.

    Any device I want to access my host (outside of my local network) requires zerotier.

    I don’t want anything outside of my control accessing my host

      Silly as it is, many ISPs hand out dynamic IPv6 prefixes that may change once in a while. Or “dynamic” prefixes that never seem to change (but are not guaranteed never to change).

      The reason is of course that they like being able to charge extra for static IPv4 addresses, and they see no reason to get rid of that revenue source for IPv6.

      I think I can ask them about it. Never really used ipv6. Maybe that’s even better. Then I can maybe use more than one IP even. I don’t know how the ISPs deal with it. Do I only get one for my router, or can I get a bunch of them… hmm

        with IPv6 you are able to address your internal network devices directly without port forwarding. Just make sure your router and other gear support it so you have everything you need.

        noip is supported by almost all consumer routers, so you’re probably paying for convenience. For homelabbers with a bit of scripting skill, it’s completely unnecessary though.

          Emphasis on “a bit,” it truly is a simple task to automate. I don’t think that anyone who has need for dynamic DNS should realistically have much trouble tackling that problem.

          For anyone who might attempt this and isn’t sure how, here’s what you need. You need a service controlling your domain with API support for updating your DNS records - some have been mentioned here, I just use gandi.net. You need to enable the API for your account/domain. Figure out how to run the command you need against the API from a scripting language of your choice - there should be documentation for the API, and it should be a single API call. Figure out how to determine your server IP from within the same scripting language. Then, write your simple script that determines the right IP and updates the record if it doesn’t match.

          All you need to do then is automate running the script - on Linux, a cron job or a systemd service and timer.

            My go to way to figure out my public IP address is curl ip.me. Very handy and easy to remember.

              My router actually has a UPnP API that I can request and get my external IP, which I like so I can poll it every few seconds and not worry about rate limiting or something.

                Meanwhile, my ISP would often rotate their customer behind their CGNAT, so the IP address from the routers upnp would often return 10.x.x.x . One of the main reason I gave up using dynamic DNS and use Tailscale instead.

            I setup my ddns domain with google before I moved to porkbun so I never looked at those features. I’m about to revamp a lot of my setup and now have more to do… I’ll check out inwx.
