parse_ipv4()
Converts IPv4 string to long (signed 64-bit) number representation.
parse_ipv4("127.0.0.1") == 2130706433
parse_ipv4('192.1.168.1') < parse_ipv4('192.1.168.2') == true
Syntax
parse_ipv4(Expr)
Arguments
| Name | Type | Required | Description |
|---|---|---|---|
| Expr | String | ✓ | A string or number representation of the IPv4 address. |
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
events
| project src_ip
| extend ip_long = parse_ipv4(src_ip)
| take 3
