Is Private IPv4 (isprivate)

[ 1 Description ] [ 2 How does it work in the search window? ] [ 3 How does it work in LINQ? ]

Description

You can apply this operation either as a Filter or Create field operation:

Filter	Returns only the private IP addresses of a selected ip field.
Create field	Creates a Boolean field that shows true if a given IP address is private.

IP addresses in the following blocks are considered as private:

10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255

How does it work in the search window?

Select Filter / Create field in the search window toolbar, then select the Is Private IPv4 operation. You need to specify one argument:

Argument	Data type

Argument	Data type
IP to test ^mandatory	ip

If you use the Create field operation, the data type of the values in the new field is boolean (true or false).

Example

In the demo.ecommerce.data table, we want to get only the events where the IP addresses in the clientIpAddress field are private. To do it, we will apply a Filter using the Is private IPv4 operation.

The arguments needed for the filter are:

IP to test → clientIpAddress field

Click Filter data. Since there are no private IP addresses in the clientIpAddress field, you will see the following result:

To add a new Boolean field that shows true when the IP addresses in the clientIpAddress field are private, click Create field and follow the same steps. In this example, you will only get false values.

How does it work in LINQ?

Use the operator where... to apply the Filter operation and select... as... to apply the Create field operation. This is the syntax for the Is Private IPv4 operation:

isprivate(ip)

Examples

You can copy the following LINQ script and try the above example on the demo.ecommerce.data table:

from demo.ecommerce.data
  where isprivate(clientIpAddress)

And this is the same example using the Create field operation:

from demo.ecommerce.data
  select isprivate(clientIpAddress) as private_ips
