How can the IP address of a user be traced back to determine the associated computer name, and what considerations should be taken into account?

To trace back the IP address of a user to determine the associated computer name, you can use a reverse DNS lookup. This involves querying the DNS server to retrieve the hostname associated with the given IP address. However, it's important to note that not all IP addresses have corresponding computer names, and some may be masked for privacy reasons. 

$ip_address = '192.168.1.1';
$hostname = gethostbyaddr($ip_address);

echo "The computer name associated with IP address $ip_address is: $hostname";
