This guide shows you how to create a DDNS-like system using Cron and a shell script. Creating your own removes the reliance on third-party DDNS providers like No-IP. I thought I’d share it here since DDNS is essential for self-hosting.
This is something I wish I’d setup sooner. For the longest time, I got comfortable with No-IP and having to manually confirm the hostname every 30 days.

Its for lucky people without CG-NAT which today means people from USA mostly…
