How can grouping available IP addresses and querying specific groups in a database improve performance when searching for free IPs?

Grouping available IP addresses can help improve performance when searching for free IPs by organizing them into smaller, manageable groups. This allows for more efficient querying of specific groups within the database, reducing the overall search time and improving performance.

// Example PHP code snippet to group available IP addresses and query specific groups in a database

// Group available IP addresses by subnet
$subnetA = array('192.168.1.1', '192.168.1.2', '192.168.1.3');
$subnetB = array('192.168.2.1', '192.168.2.2', '192.168.2.3');

// Query specific group for free IPs
$subnet = 'subnetA';
$query = "SELECT ip_address FROM ip_addresses WHERE subnet = '$subnet' AND status = 'free'";
$result = mysqli_query($connection, $query);

// Process query results
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "Free IP Address: " . $row['ip_address'] . "<br>";
    }
} else {
    echo "No free IP addresses found in subnet $subnet";
}
