I run ddclient on a local machine and it updates my Cloudflare DNS records if my IP changes.
OPNSense has it built in too, if you use it. So does PFSense, I think. Been a while, might be misremembering.

I use duckdns.org , but if you are trying to host a webpage I totally recommend using Cloudflare, Cloudflare tunnels and a reverse proxy like nginx.
Setting it up may be a bit tricky, but it is a gamechanger. I followed Ibracorp's guides and I had no problem.
I use a Cloudflare tunnel rather than a dynamic DNS provider. Some in the self hosting community are opposed to Cloudflare, but I appreciate the tools they provide (especially Zero Trust so I can put my self hosted apps behind Okta).
+1 for tunnels, easy to use and no port forwarding required
I use DuckDNS. There's been only one outage for the ~2 years I've been using it and it's free. I also use DuckDNS to acquire the SSL certificates for the reverse proxy.
How gave you set it up out of curiosity?
If you mean automatically update IP part, duckdns website has a very comprehensive guide.
If you mean getting a free SSL certificate, you can use acme.sh (this is what I used) which has integrated support for duckddns (To use let's encrypt you need to use --server letsencrypt in your command)
I also use duckdns, but in the last year it went down like twice or something. Its good but not really reliable.

I host my own ddns server in a debian container https://wiki.debian.org/DDNS
Here we go down another rabbit hole... 😆
Right!!!! Lmao 😂 same boat as ya lol
If you only need public access to things like HTTP or SSH you don’t necessarily need to run dynamic ip and just setup Cloudflare Tunnels. So far I haven’t needed to put anything public that doesn’t run on the provided tunnels.

DNS managed by Cloudflare, and cf-ddns
2nd, but with just a bash script. Also, I'm forwarding http & https to different IPs and the best thing about cloudflare is that you can restrict those ports to only be open when coming from cloudflare's proxy. I like the extra layer of security, and dislike that they can see all traffic..
I'm using DuckDNS, it has a plugin for pfSense / OpnSense.
your domain provider probably has an api to update dns records i use cloudflare with their api because then i can hide my ip behind their proxy or if i don't have a public ip i can use their tunnels
Does your domain provider have a DDNS service? I buy my domains from namecheap.com and use their DDNS service for exactly what you're describing.
I have NameCheap as well. I found their Windows client after I made this post. I'm still curious is there are better services out there. It seems Cloudflare may have the best tools for security for a webserver, i.e. hiding the real IP address.
I use namecheap and dd client. Happy to share my config file if you need if.
The easiest thing to do is to use https://www.duckdns.org/ and then point your domain as a CNAME to this duckdns subdomain.
My IP isn’t technically static but it hasn’t changed in the 3 years I’ve been with this ISP.
This. But I use namecheap and the built in tool on pfsense to keep an A record up to date if it ever changed.
I should automate something like that too. I just have one A record pointing to my IP and all my subdomains CNAME’d to that so that if it ever changes, I just have to update that one record.
I have NameCheap as well. I was trying to set this up with the ddclient on OPNSense but the logs suggested it couldn't connect to NameCheap. What do you need to authenticate other than the DDNS passcode supplied by NameCheap?
dedyn.io
If you're using godaddy, you can use a script to do your own dynamic DNS:
https://www.instructables.com/Quick-and-Dirty-Dynamic-DNS-Using-GoDaddy/
I use this container, favonia/cloudflare-ddns, for Cloudflare and my domain.
First step would be to ensure that you can do port forwarding.
- Check if your IP address isn't a private one or CGNAT.
- Now set up reverse proxy and try connecting to your service. If it connects, you are okay.
- Now this is something i didn't know could happen but it did end up happening to me. I was happily port forwarding for a few months, until suddenly my port forwarding stopped working. Now I called my ISP, they said they did nothing(my ISP is a few guys who have no Idea about what they are doing, the other option to them is 512kbps DSL connection) at this point all my ingress ports are blocked and even outgoing ssh is blocked. Then the new month starts and everything is working again. I looked at my ISP website to get an idea of what may have caused this and the case seems to be that it was the first time I crossed 100GB in uploading. So my ISP has configured things such a way that port forwarding only works for the first 100GB of uploading.
This is why I strongly recommend cloudfare tunnel or any other similar solution.
Afraid.org is what I've been using ever since dyndns started charging big prices for what used to be free.
I use cloudflare and have a dyndns client running on my synology nas
DNS-O-Matic (recommended by CloudFlare, among others) combined with SWAG and Authelia will handle dynamic DNS, reverse proxying, SSL certificates, and MFA. SWAG (nginx, Let's Encrypt and Certbot) and Authelia (MFA) run nicely in a 2 container Docker stack.
Mine have been running for ~18 months on my NAS, though I have a fixed IP so no longer use a DDNS provider.
duckdns and ydns
I pay an extra £1 a month to my ISP to get a static address. Figured it's well worth having no hassle.
Before, I used to use duckdns. Completely free and super simple
Nowadays I just have a docker container that updates my A records on my domain directly through namesilo's API. Took like 5 mins to set up the config
Aside from a brief scare a couple of months ago, when the owner/operator was unreachable and the configuration interface and some automatic update paths were not working, I have been using afraid.org, and it has proven to be a stellar service, and free for basic needs.
