What are the advantages and disadvantages of creating a custom database with IP ranges for country information in PHP?

Issue: Storing country information in a custom database with IP ranges in PHP can provide faster and more efficient lookups for country data based on IP addresses. However, maintaining and updating the database with accurate IP ranges can be challenging and time-consuming. Additionally, the accuracy of the country information may not always be guaranteed due to changes in IP allocations. 

// Sample PHP code for creating a custom database with IP ranges for country information

// Connect to the custom database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "country_info";

$conn = new mysqli($servername, $username, $password, $dbname);

// Create table for storing IP ranges and country information
$sql = "CREATE TABLE ip_country (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    start_ip VARCHAR(50) NOT NULL,
    end_ip VARCHAR(50) NOT NULL,
    country VARCHAR(50) NOT NULL
)";

if ($conn->query($sql) === TRUE) {
    echo "Table ip_country created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

// Insert sample data into the table
$sql = "INSERT INTO ip_country (start_ip, end_ip, country)
VALUES ('192.168.1.1', '192.168.1.255', 'United States')";

if ($conn->query($sql) === TRUE) {
    echo "Sample data inserted successfully";
} else {
    echo "Error inserting data: " . $conn->error;
}

// Close the database connection
$conn->close();
