Storing IP Addresses in MySQL Using PHP

Determining the optimal field type and approach for storing IP addresses in a MySQL database is crucial when working with PHP.

Field Type:

The recommended field type for storing IPv4 addresses is an INT, as this provides the most efficient storage. For IPv6 addresses, a BINARY field is preferred.

Storage Method:

IPv4 Addresses:

• Convert the IP address to an integer using PHP's ip2long().
• Store the integer value in an INT field in the database.

IPv6 Addresses:

• Convert the IP address to a binary string using PHP's inet_pton().
• Store the binary string in a BINARY field in the database.

Retrieval:

IPv4 Addresses:

• Retrieve the integer from the INT field.
• Convert the integer back to an IP address using either MySQL's INET_NTOA() function or PHP's long2ip().

IPv6 Addresses:

• Retrieve the binary string from the BINARY field.
• Convert the binary string back to an IP address using PHP's inet_ntop().
