A brief introduction to ip address storage in Mysql

This article mainly shares with you a brief introduction to IP address storage in Mysql, hoping to help everyone.

1. For ip addresses, mysql database storage has two general formats: string and integer.

String varchar(20)：”192.168.1.10”

Integer type int(10 )：3232235786

The conversion format is as follows:

# INET_ATON(expr) 给出一个作为字符串的网络地址的点地址表示，返回一个代表该地址数值的整数。地址可以是4或8比特地址。
mysql> select INET_ATON('192.168.1.10') ; 
+---------------------------+
| INET_ATON('192.168.1.10') |
+---------------------------+
|                3232235786 |
+---------------------------+
1 row in set (0.00 sec)
 # INET_NTOA(expr) 给定一个数字网络地址 (4 或 8 比特),返回作为字符串的该地址的电地址表示。
mysql> Select INET_NTOA(3232235786);
+-----------------------+
