以上对我来说很好。
下面开始编辑
对于以下内容，尝试在stijn-de-witt在评论中提出观点后改进此答案。
但是请注意，评论中引用的博客在进入整数的更新语句中存在错误。所以暂时直到我解决这个问题，我发现了一个 varchar 修改，如下所示。
Edit1（更多内容，请参阅答案下方的评论）：
Alter the table to get a "from ip to ip range"
alter table thing1 add column from_ip varchar(20), add column to_ip varchar(20);
-- note that those two are nullable at the moment. You can always change that later
刚刚添加的 varchar 的更新表
update thing1
set from_ip= INET_NTOA(INET_ATON( SUBSTRING_INDEX(network, '/', 1))
& 0xffffffff ^ ((0x1 << ( 32 - SUBSTRING_INDEX(network, '/', -1)) ) -1 )),
to_ip= INET_NTOA(INET_ATON( SUBSTRING_INDEX(network, '/', 1))
| ((0x100000000 >> SUBSTRING_INDEX(network, '/', -1) ) -1 ))
select * from thing1;
（对于上述更新声明，感谢 Bernd Bufen 在这个答案中）
上述更新语句的结果：
mysql> select network,from_ip,to_ip from thing1;
+------------+---------+-----------+
| network | from_ip | to_ip |
+------------+---------+-----------+
| 1.0.1.0/24 | 1.0.1.0 | 1.0.1.255 |
| 1.0.2.0/23 | 1.0.2.0 | 1.0.3.255 |
| 1.0.4.0/22 | 1.0.4.0 | 1.0.7.255 |
+------------+---------+-----------+
从这里，查看 MySQL 手册页Miscellaneous Functions for INET_ATON(expr).
Edit2（再次感谢stijn-de-witt）：
alter table thing1 add column uint_from_ip int unsigned, add column uint_to_ip int unsigned;
UPDATE thing1 SET uint_from_ip = inet_aton(SUBSTRING(network, 1, LOCATE('/', network) - 1)),
uint_to_ip = (inet_aton(SUBSTRING(network, 1, LOCATE('/', network) - 1)) + (pow(2, (32-CONVERT(SUBSTRING(network, LOCATE('/', network) + 1), UNSIGNED INT)))-1));
结果：
select network,from_ip,to_ip,uint_from_ip,uint_to_ip from thing1;
+------------+---------+-----------+--------------+------------+
| network | from_ip | to_ip | uint_from_ip | uint_to_ip |
+------------+---------+-----------+--------------+------------+
| 1.0.1.0/24 | 1.0.1.0 | 1.0.1.255 | 16777472 | 16777727 |
| 1.0.2.0/23 | 1.0.2.0 | 1.0.3.255 | 16777728 | 16778239 |
| 1.0.4.0/22 | 1.0.4.0 | 1.0.7.255 | 16778240 | 16779263 |
+------------+---------+-----------+--------------+------------+
