IP Address Masking

IP address masking applies a built-in mask format to change IP addresses. Mask string datatypes with IP address masking.

Use IP address masking to mask data with the string datatype.

IP masking splits an IP address into four numbers, separated by periods. The first number is the network. The PowerCenter Integration Service masks the network number within the network range.

The PowerCenter Integration Service does not mask the class and private network address. The PowerCenter Integration Service masks a Class A IP address as a Class A IP Address and a 10.x.x.x address as a 10.x.x.x address.

For example, the PowerCenter Integration Service can mask 11.12.23.34 as 75.32.42.52, and 10.23.24.32 as 10.61.74.84.
