I recently had to write a component for an application which allows users to inspect an IP address in detail as well as validate the address against various different criteria. I couldn’t find an API which provides this type of functionality in any of the Adobe classes so I wrote my own. I figured someone else may need to do something similar at some point so I am publishing the API under the MIT License.

The IPV4 API allows detailed inspection of an IP version 4 address (IPv4). It provides a robust API which is not available from Adobe at the moment. Usage is simple and straight forward and contains methods which perform the following:

• Determine if the address specified is a valid IP address
• Determine the network class of the specified IP Address
• Determine the network octet of the specified IP Address
• Determine the host octet of the specified IP Address
• Determine if the IP Address is valid for Network assignment
• Determine if the IP Address is within the Class range specified
• Determine if the IP Address is a loopback address.

Below is a simple usage example which performs various operations on a specific IP Address:

import com.ericfeminella.net.IPV4Inspector;

var ip:IPV4Inspector = new IPV4Inspector("23.14.189.200");

trace("Network Class: " + ip.getNetworkClass());

trace("Is valid IP Address: " + ip.isValid());

trace("Network: " + ip.getNetworkOctet());

trace("Host: " + ip.getHostOctet());

trace("Is loopback: " + ip.isLoopback());

trace("Is valid network host: " + ip.isValidNetworkHost());
Outputs:

// Network Class: Class A

// Is valid IP Address: true

// Network: 23

// Host: 14.189.200

// Is loopback: false

// Is valid network host: true

The IPV4 inspector API can be used for inspecting and validating an IP Address. I plan on adding an update which contains methods for dealing with masks and prefix notation as well.
