要存储IPv4,您可以使用 INT UNSIGNED
,对于IPv6,你需要一个十进制(39,0),
来在表中存储一个ip,你可以使用函数 INET_ATON
:
To store an IPv4 you can use an INT UNSIGNED
, while for a IPv6 you need a decimal(39,0),
to store an ip in the table you can use the function INET_ATON
:
INSERT INTO table (ipcol) VALUES (INET_ATON('192.168.0.10'));
并使用函数 INET_NTOA
将其检索回来:
and retrieve it back with the function INET_NTOA
:
SELECT INET_NTOA(ipcol) AS ip FROM table;
这是在MySQL IPv6支持之前得到的答案; 用户应该知道MySQL现在本身支持IPv6: https://dev.mysql.com/doc/refman/5.6/en/miscellaneous-functions.html
This answered existing before MySQL IPv6 support; users should be made aware that MySQL now natively supports IPv6: https://dev.mysql.com/doc/refman/5.6/en/miscellaneous-functions.html
