The first function aids the developer by converting a string format IPv4 address such as “192.168.1.2” to its hexadecimal equivalent. The second function is used to configure an interface with the specified IPv4, network mask and gateway addresses. An example is shown in listing Listing - IPv4 Address Configuration Example.
