Learn how to use the parse_ipv4_mask() function to convert an IPv4 input string and netmask to a 64-bit wide long number in big-endian order.

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

Syntax

parse_ipv4_mask(ip , prefix)

Parameters

NameTypeRequiredDescription
ipstring✔️The IPv4 address to convert to a long number.
prefixint✔️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 is a long number. If conversion isn’t successful, the result is null.
