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().
