How can a dyndns address be used to solve the issue of retrieving the correct IP address in PHP?

Issue: When trying to retrieve the correct IP address in PHP, the dynamic nature of IP addresses can make it difficult to accurately determine the user's IP address. Using a dyndns address can help solve this issue by providing a static domain name that always points to the current IP address of the user. PHP Code Snippet: 

$dyndns_address = "example.dyndns.org";
$user_ip = gethostbyname($dyndns_address);

echo "User's IP address: " . $user_ip;
