Duck DNS – free dynamic DNS hosted on AWS

For anyone hosting their domain on Google Domains, there's a neat API endpoint they're offering for updating the DNS with a simple CURL. I've been using this for years now for a public Raspberry PI behind a home router that changes IPs every other day. curl -s -k --user "username:password" "https://domains.google.com/nic/update?hostname=yourdomain.com" There's more parameters (and you can specify an IP, the above request only takes the caller's IP). Here are the docs…

Fond memories of using DDNS on old Netgear routers at home in the aughts and port forwarding services with some rudimentary firewall rules and tcpwrappers to try and lock down access. Now I use a combination of Tailscale[1] for private services only to me and Tailscale Funnels[2], and Cloudflare Tunnels[3] for public service exposure. This accomplishes the same thing I was doing with DDNS and my ISP IP, but in a much more secure and stable manner. 1. https://tailscale.com/ 2…

Is this related in any way to the DDG search engine?

Nice idea! Although if you’re going to it, use POST instead of GET as GET requests are not for updates but for idempotent requests.
