The problem it solves

If your internet provider changes your home or office IP address, anything you host there, like a personal server or remote access tool, becomes unreachable until you manually update your DNS settings. Checking and updating this by hand is easy to forget.

Who it fits

Anyone self-hosting a server or service from a location without a fixed IP address.

How it works

  1. On a regular schedule, the system checks your current public IP address
  2. It compares that to what's on file for each of your subdomains
  3. If the IP has changed, it updates Namecheap's dynamic DNS with the new address
What you get

Servers you can always reach from anywhere

Your self-hosted server stays reachable at the same address even when your internet provider changes your public IP address.

What you get

An always-current DNS record, so your domain keeps pointing to your server even after your IP changes.

What you need

A Namecheap domain with dynamic DNS enabled.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.
