Converts the input string of IPv4 and netmask to a signed, 64-bit wide, long number representation in big-endian order.

parse_ipv4_mask("127.0.0.1", 24) == 2130706432
parse_ipv4_mask('192.1.168.2', 31) == parse_ipv4_mask('192.1.168.3', 31)
tohex(parse_ipv4_mask('127.2.3.4', 32)) == '7f020304'

Syntax

parse_ipv4_mask(Expr, PrefixMask)

Arguments

  • Expr: A string representation of the IPv4 address that will be converted to long.
  • PrefixMask: An integer from 0 to 32 representing the number of most-significant bits that are taken into account.

Returns

If conversion is successful, the result will be a long number. If conversion isn't successful, the result will be null.
