Hi, we host 3 Natural Selection servers in Argentina, and unfortunately, we keep needing to unnecessarily update them because they are registered by IP even though we always add them by hostname. We can't use IPs because our internet provider does not give us static IPs; therefore, we use a dynamic DNS service with Cloudflare. Can you replace the way you track them?

Moved: Not a Gametracker bug.

There are only two practical ways to track a game server:
1) IP address + port number;
2) A DNS name + port number pointing to the correct server IP address.

As far as I am aware the only reason for an new IP address to be allocated by your ISP is because the router or possibly the physical computer is switched off.
Leave both on / running.

Alternatively;
1) Fill in the DNS address on the GT server pages;
2) Update the IP address on the DNS settings when the IP changes.
