IP函数

IPv4NumToString(num)

接受一个UInt32(大端)表示的IPv4的地址,返回相应IPv4的字符串表现形式,格式为A.B.C.D(以点分割的十进制数字)。

IPv4StringToNum(s)

与IPv4NumToString函数相反。如果IPv4地址格式无效,则返回0。

IPv4NumToStringClassC(num)

与IPv4NumToString类似,但使用xxx替换最后一个字节。

示例:

SELECT
    IPv4NumToStringClassC(ClientIP) AS k,
    count() AS c
FROM test.hits
GROUP BY k
ORDER BY c DESC
LIMIT 10
┌─k──────────────┬─────c─┐
 83.149.9.xxx    26238 
 217.118.81.xxx  26074 
 213.87.129.xxx  25481 
 83.149.8.xxx    24984 
 217.118.83.xxx  22797 
 78.25.120.xxx   22354 
 213.87.131.xxx  21285 
 78.25.121.xxx   20887 
 188.162.65.xxx  19694 
 83.149.48.xxx   17406 
└────────────────┴───────┘

由于使用'xxx'是不规范的,因此将来可能会更改。我们建议您不要依赖此格式。

IPv6NumToString(x)

接受FixedString(16)类型的二进制格式的IPv6地址。以文本格式返回此地址的字符串。 IPv6映射的IPv4地址以::ffff:111.222.33。例如:

SELECT IPv6NumToString(toFixedString(unhex('2A0206B8000000000000000000000011'), 16)) AS addr

IPv6StringToNum(s)

与IPv6NumToString的相反。如果IPv6地址格式无效,则返回空字节字符串。 十六进制可以是大写的或小写的。

IPv4ToIPv6(x)

接受一个UInt32类型的IPv4地址,返回FixedString(16)类型的IPv6地址。例如:

SELECT IPv6NumToString(IPv4ToIPv6(IPv4StringToNum('192.168.0.1'))) AS addr

cutIPv6(x, bitsToCutForIPv6, bitsToCutForIPv4)

接受一个FixedString(16)类型的IPv6地址,返回一个String,这个String中包含了删除指定位之后的地址的文本格式。例如:

    IPv4ToIPv6(IPv4StringToNum('192.168.0.1')) AS ipv4
