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:

  1. SELECT
  2. IPv4NumToStringClassC(ClientIP) AS k,
  3. count() AS c
  4. FROM test.hits
  5. GROUP BY k
  6. ORDER BY c DESC
  7. LIMIT 10
  1. ┌─k──────────────┬─────c─┐
  2. 83.149.9.xxx 26238
  3. 217.118.81.xxx 26074
  4. 213.87.129.xxx 25481
  5. 83.149.8.xxx 24984
  6. 217.118.83.xxx 22797
  7. 78.25.120.xxx 22354
  8. 213.87.131.xxx 21285
  9. 78.25.121.xxx 20887
  10. 188.162.65.xxx 19694
  11. 83.149.48.xxx 17406
  12. └────────────────┴───────┘

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:

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

  4. FROM hits_all
  5. WHERE EventDate = today() AND substring(ClientIP6, 1, 12) != unhex('00000000000000000000FFFF')
  6. GROUP BY k
  7. ORDER BY c DESC

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)
