parse_ipv4_mask

The parse_ipv4_mask function 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( Expression, PrefixMask )

Arguments

​

• Expression: String expression representing IPv4 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.

Results

​

If the type conversion is successful, returns a long number.

If the conversion fails, returns null.

Examples

​

This example returns 3232235776:

print theData='192.168.1.2'  | extend theMask=24, parsed_data=parse_ipv4_mask(theData,theMask) | render event

This example returns 2130706432:

parse_ipv4_mask("127.0.0.1", 24)

This example returns parse_ipv4_mask('192.1.168.3', 31):

parse_ipv4_mask('192.1.168.2', 31)` returns as `parse_ipv4_mask('192.1.168.3', 31)
