A

INET_ATON(ip) is a MySQL built-in function that converts an IP address from string format to number. It uses the following conversion formula:

INET_ATON('p₁.p₂.p₃.p₄') = INET_ATON(p₁×256³ + p₂×256² + p₃×256 + p₄

For example:

SELECT INET_ATON('10.0.5.9'), 10*POW(256,3) + 0*POW(256,2) + 5*256 + 9;
  -- +-----------------------+------------------------------------------+
  -- | INET_ATON('10.0.5.9') | 10*POW(256,3) + 0*POW(256,2) + 5*256 + 9 |
  -- +-----------------------+------------------------------------------+
  -- |             167773449 |                                167773449 |
  -- +-----------------------+------------------------------------------+

SELECT INET_ATON('127.0.0.1'), 127*POW(256,3) + 0*POW(256,2) + 0*256 + 1;
  -- +------------------------+-------------------------------------------+
  -- | INET_ATON('127.0.0.1') | 127*POW(256,3) + 0*POW(256,2) + 0*256 + 1 |
  -- +------------------------+-------------------------------------------+
  -- |             2130706433 |                                2130706433 |
  -- +------------------------+-------------------------------------------+
