Functions for working with IP addresses
|
|
---------------------------------------
|
|
|
|
IPv4NumToString(num)
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
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).
|
|
|
|
IPv4StringToNum(s)
|
|
~~~~~~~~~~~~~~~~~~
|
|
The reverse function of IPv4NumToString. If the IPv4 address has an invalid format, it returns 0.
|
|
|
|
IPv4NumToStringClassC(num)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
Similar to IPv4NumToString, but using ``xxx`` instead of the last octet.
|
|
|
|
Example:
|
|
|
|
.. code-block:: sql
|
|
|
|
SELECT
|
|
IPv4NumToStringClassC(ClientIP) AS k,
|
|
count() AS c
|
|
FROM test.hits
|
|
GROUP BY k
|
|
ORDER BY c DESC
|
|
LIMIT 10
|
|
|
|

└────────────────┴───────┘
|
|
|
|
Since using ``'xxx'`` is highly unusual, this may be changed in the future. We recommend that you don't 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``. Examples:
|
|
|
|
.. code-block:: sql
|
|
|
|
SELECT IPv6NumToString(toFixedString(unhex('2A0206B8000000000000000000000011'), 16)) AS addr

|
|
count() AS c
|
|
FROM hits_all
|
|
WHERE EventDate = today() AND substring(ClientIP6, 1, 12) != unhex('00000000000000000000FFFF')
|
|
GROUP BY k
|
|
ORDER BY c DESC
|
|
LIMIT 10

IPv6StringToNum(s)
|
|
~~~~~~~~~~~~~~~~~~
|
|
The reverse function of IPv6NumToString. If the IPv6 address has an invalid format, it returns a string of null bytes.
|
|
HEX can be uppercase or lowercase.
