mysql – 检查ipv6是否在范围内

我有maxmind的ipv6数据.这是我当前的表(带有示例数据)：

+---------------+------------+
|    network    | geoname_id |
+---------------+------------+
| 2001:208::/32 |        123 |
| 2001:218::/32 |       4312 |
+---------------+------------+

使用their converter,我可以创建network_start_ip和network_last_ip列：

+------------------+----------------------------------------+------------+
| network_start_ip |            network_last_ip             | geoname_id |
+------------------+----------------------------------------+------------+
| 2001:200::       | 2001:200:ffff:ffff:ffff:ffff:ffff:ffff |        123 |
| 2001:208::       | 2001:208:ffff:ffff:ffff:ffff:ffff:ffff |       4312 |
+------------------+----------------------------------------+------------+

我期待这样的东西会起作用(即使它可能比其他方法慢)：

SELECT b.geoname_id FROM blocks b 
WHERE HEX(INET6_ATON('2001:201:ffff:ffff:ffff:ffff:ffff:ffff')) BETWEEN HEX(b.network_start_ip) AND HEX(b.network_last_ip)

那么,我错过了什么？另外,存储ipv6地址(范围)的最佳方法是什么

谢谢

解决方法:

以下是我的工作方式：

>创建了具有相同列的另一个表,但network_start_ip和network_last_ip是VARBINARY(16)
>使用以下语句填充该表：INSERT INTO块
SELECT INET6_ATON(b2.network_start_ip),INET6_ATON(b2.network_last_ip),b2.geoname_id FROM blocks_copy b2;
>然后,要检查IPv6地址是否在范围内,我只需要运行此查询：SELECT geoname_id FROM blocks b
INERE6_ATON(‘2a01：4ff：ffff：ffff :: ffff’)BETWEEN b.network_start_ip和b.network_last_ip
