Clickhouse IP 函数

IPv4NumToString(num)

将数字类型ip转换为IPv4格式。

Takes a UInt32 number. Interprets it as an IPv4 address in big endian. Returns a string containing the corresponding IPv4 address in the format A.B.C.d (dot-separated numbers in decimal form).

Alias: INET_NTOA.

IPv4StringToNum(s)

将IPv4转换为数字。

The reverse function of IPv4NumToString. If the IPv4 address has an invalid format, it throws exception.

Alias: INET_ATON.

IPv4StringToNumOrDefault(s)

Same as IPv4StringToNum, but if the IPv4 address has an invalid format, it returns 0.

IPv4StringToNumOrNull(s)

Same as IPv4StringToNum, but if the IPv4 address has an invalid format, it returns null.

IPv4NumToStringClassC(num)

Similar to IPv4NumToString, but using xxx instead of the last octet.

Example:

复制代码
SELECT
    IPv4NumToStringClassC(ClientIP) AS k,
    count() AS c
FROM test.hits
GROUP BY k
ORDER BY c DESC
LIMIT 10

┌─k──────────────┬─────c─┐

Since using 'xxx' is highly unusual, this may be changed in the future. We recommend that you do not rely on the exact format of this fragment.

IPv6NumToString(x)

Accepts a FixedString(16) value containing the IPv6 address in binary format. Returns a string containing this address in text format. IPv6-mapped IPv4 addresses are output in the format ::ffff:111.222.33.44.

Alias: INET6_NTOA.

Examples:

复制代码
SELECT IPv6NumToString(toFixedString(unhex('2A0206B8000000000000000000000011'), 16)) AS addr;
