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’ve used big names like ns1 and Cloudflare for free.
I use TailScale and their free Personal plan.
Disclaimer though: I haven’t done much due diligence on it. It was easy to install when I first started self hosting with Umbrel and I use it so rarely that it’s good enough for my usage.
I want to be independent. My understanding is that Tail scale relies on a service they run or a endpoint you run on a VPS - Is that right?
Oh right, yeah you’re dependent on their service.
VPS with a tunnel between it and home services (Wireguard/Tailscale, etc)in my opinion is Best Way as it isolates your home gateway (no open ports, because you make outbound connections to your VPS), and let VPS handle Identity and Access Management
(Or an equivalent isolating architecture).
Alternatively, Tailscale has a Funnel feature which can route public traffic into your Tailscale network. Though I don’t love this approach, it does work for low-volume connections.
+1 for using Tailscale funnel Don’t use a lot of resources and easy to setup
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?
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.

Many registrars let you buy a domain and set up dynamic DNS for it within their system so you can own a domain and get dyndns on it.
Otherwise you could accomplish it with a VPS but you’d only need the smallest one available because it would just need to run nginx to forward to your home ip (and a small tool to update that IP when it changes). So you could probably get something for less than $5/mo.
FreeDNS works pretty well as long as you don’t need more than 5 DNS records.
Other free services I had good experiences with:
You can pay for dyndns service which should be more reliable than free ones. I don’t have any experience with those, so I can’t give any recommendations. What I’m running is that I use few of the free ones which are updated either from my router or from a linux VM and I’ve just pointed few easy to remember CNAME records from my own domain to those dynamic addresses. It’s not the best thing in the world, but my dynamic IP tends to be pretty static as it usually changes only when my own hardware is down for a longer period of time (few hours or so, so a longer power outage or a hardware maintenance gone wrong).
Many DNS providers have an API and are supported by various dynamicDNS clients. I use Cloudflare and the built in client on my Opnsense router.
OpenWRT should have a client too that supports a bunch of services.
How often does your IP actually change? Mine changes so rarely (during extended power outages, say) that I am able to just update my IP manually when it does.
I even used to run my own authoritative DNS server at home (the one offered by my registrar isn’t configurable enough, think SRV and TXT records) - for that, I have a web UI at my registrar to set the IP addresses of the DNS server.
I have dyndns, have since they were 10$ a year, and I’ve gradually realized that my ISP changes my IP on average less than once a year…
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’ve been using No-IP free plan for years without issues. Inputted the credentials to my routers DDNS client and then basically forgot about it. Free users need to confirm their account once a month via email but that’s just one click.
If your domain registrar happens to have an API to update DNS entries, you could implement DDNS yourself by writing a simple automated script to check the external IP (e.g. via ipify.org) and if it’s changed from the last check then call the API to update the DNS entries.
Yeah been using No-ip free but I worry that one day I will forget to confirm and ill ge cut-off.
No-IP
Don’t recommend that. There are plenty of better alternatives such as https://freedns.afraid.org/ and https://www.duckdns.org/ that aren’t run by predatory companies that may pull the plug like DynDNS did.
Sure. I’m not recommending anything, just stating what has worked for me. For simple use cases, I think most of the DDNS services are pretty much the same anyway and it’s easy to switch to an another one if one stops working for some reason.
Get your own domain, find a free DNS service that provides an API, and it becomes a simple matter of updating a DNS
Arecord whenever your IP changes.Here’s a starting point: https://community.letsencrypt.org/t/dns-providers-who-easily-integrate-with-lets-encrypt-dns-validation/86438
Don’t use a DynamicDNS service, they’re usually crap and they make you depend on a domain you don’t own.
Free Dyndns services seem to be a bit crap
Why do you say that? https://freedns.afraid.org/ and https://www.duckdns.org are very solid and if you’re looking for something more corporate even Cloudflare offers that service for free.
DuckDNS is great… but they have had some pretty major outages recently. No complaints, I know it’s an extremely valuable free service but it’s worth mentioning.
