Storing IP Addresses in MySQL Databases Using PHP

When working with IP addresses, selecting the appropriate field type and storage method in MySQL databases is crucial for efficient data handling. This question explores the best practices for storing IP addresses using MySQL and PHP.

To store IPv4 addresses, the most efficient field type is an INT (integer), rather than a VARCHAR. To convert an IPv4 address to an integer, use PHP's ip2long function. To convert the integer back to an IP address, use MySQL's INET_NTOA function or PHP's long2ip function.

For storing IPv6 addresses, a BINARY field is recommended. To convert an IPv6 address to a binary string, use PHP's inet_pton function. To convert the binary string back to an IPv6 address, use PHP's inet_ntop function.

By adhering to these practices, you can ensure optimal storage and retrieval of IP addresses within MySQL databases using PHP, maximizing efficiency and data integrity.
