Im sure this has been asked before i juat can’t find where it has been - Maybe need to work on how to search Lemmy better. But…
Id like to eventually self host some sevices that require external access. While I have IpV6 addresses my IPV4 is dynamic.
Whats the best free way to be able to point some domains/ subdomains I have to my external dynamic IP and keep it updated. Im running OpenWrt on my router. - So possibly should be posting there.
Free Dyndns services seem to be a bit crap. Do I need to pay for a VPS? (seems to defeat the point of self hosting)
I use afraid.org to keep my dynamic dns pointed at my routers ip. With afraid.org dns you only need a curl statement scheduled on the open
dnswrt router to keep the dynamic ip updated.Self hosting doesn’t mean you should host everything yourself at home, using a VPS you manage (so the data inside it is still yours) is also a viable option for selfhosting. I myself host some services at home and a few others in a VPS.
As for Dyndns, I’ve used a few providers over the years. DuckDNS is the one I’ve been using for 5 years or so and it’s not failed me once. Pretty happy with it.
Maybe you could have a duckdns pointing to your dynamic IP and your domains / subdomains with a CNAME pointing to the dyndns address?
Since you run already OpenWrt, you can check out https://openwrt.org/docs/guide-user/services/ddns/client
There is a list on this page of compatible services. If you don’t want to use one more service (DNS), you can use a domain registrar with an API (like porkbun) and find online tools that work with that.
Be aware of the risks of hosting your websites publicly from home, make sure to run them in very isolated environments. Having your VPS compromised is bad, but having your home network compromised is much worse!
That lists afraid.org as a ddns provider.
They are pretty great, I use them as my domain host.

Agree - Not something I will throw myself into.
Yes I use no-ip but have to confirm the domain name every month or so and cant use my own domain on the free tier. (Maybe im just being cheap) - Also I haven’t been able to figure out how I would use / get SSL certificates.
Try duckdns, it doesnt nag you every month and it just works
Yes, I have used it in the past and it was annoying…
You can get SSL certs with letsencrypt, but you need to use the http verification method.
Not anymore, it supports txt records now
Many DNS providers have an API and are supported by various dynamicDNS clients. I use Cloudflare and the built in client on my Opnsense router.
OpenWRT should have a client too that supports a bunch of services.
ddclient paired with a supported provider.
There are two options, one is tunneling (e.g. tailscale, cloudfare tunnels, or a VPS either with special software or plain old SSH port forward constant connection). The other option, the most popular answer (I think, influenced by how yoy asked) is Dynamic DNS or DynDNS (e.g. duck, hurricane, freedns, etc.) this second one is like the classic solution.
I’m using cloudflare as my nameserver and the free API seems to work just fine with ddclient.
You can get super cheap VPSs and use them just as a reverse proxy (with access via VPN). I host 11 servers using one single-core VPS as a reverse proxy. All data resides on premises, in house. I pay 10/yr for VPS. It definitely does not defeat the purpose.
From where can you get a VPS for that price?
Check out low end box. I found coupons for racknerd. I have one VPS that’s $10/yr, another that’s $18/yr. I’ve had zero downtime in the 18 months I’ve used them. No complaints from me. YMMV of course.
Yeah maybe I need to consider this.
Namecheap domains include a dynamic DNS application for free and it works well. Be aware that it only runs on Windows.
also keep in mind for people not on windows, namecheaps API only functions for business grade, and also is not clearly documented, there is a “dynamic dns setup page” but it isn’t up to date. I find myself trying to use openwrt’s DDNS pages for it but it still isn’t accurate, I am likely going to transfer elsewhere when im closer to the end of my lease. This API restriction also prevents you from easily automating your SSL process using letsencrypt as you are locked down to subdomain based entries instead of wildcard domains.
Script that checks your external IP and updates your DNS provider via API.
If you go down the VPS route, a headscale server on a cheap $3.50 VPS would be the way to go. Wouldn’t even have to deal with IP addresses at that point, while still being able to self-host all your services, with the cheap VPS being a glorified switch/firewall.

I have dyndns, have since they were 10$ a year, and I’ve gradually realized that my ISP changes my IP on average less than once a year…
I think you got enough recommendations for several tunneling solutions.
Apart from that (and free DynDNS) you could also use a regular paid DNS provider. Some of them also offer DynDNS or an API. I think I saw some regular providers in the list of my DynDNS client on my router, next to the super cheap or free ones.
Cloudflare has an api for easy dynamic dns. I use oznu/docker-cloudflare-ddns to manage this, it’s super easy:
docker run \ -e API_KEY=xxxxxxx \ -e ZONE=example.com \ -e SUBDOMAIN=subdomain \ oznu/cloudflare-ddnsThen I just make a CNAME for each of my public facing services to point to ‘subdomain.example.com’ and use a reverse proxy to get incoming traffic to the right service.
FreeDNS works pretty well as long as you don’t need more than 5 DNS records.
Other free services I had good experiences with:
