Converts IPv4 string to long (signed 64-bit) number representation in big-endian order.

parse_ipv4("127.0.0.1") == 2130706433
parse_ipv4('192.1.168.1') < parse_ipv4('192.1.168.2') == true
tohex(parse_ipv4('127.2.3.4')) == '7f020304'

Syntax

parse_ipv4(Expr)

Arguments

  • Expr: String expression representing IPv4 that will be converted to long. String may include net-mask using IP-prefix notation.

IP-prefix notation

IP addresses can be defined with IP-prefix notation using a slash (/) character. The IP address to the LEFT of the slash (/) is the base IP address. The number (1 to 32) to the RIGHT of the slash (/) is the number of contiguous 1 bit in the netmask.

For example, 192.168.2.0/24 will have an associated net/subnetmask containing 24 contiguous bits or 255.255.255.0 in dotted decimal format.

Returns

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

Example

datatable(ip_string:string)
[
 '192.168.1.1',
 '192.168.1.1/24',
 '255.255.255.255/31'
]
| extend ip_long = parse_ipv4(ip_string)
