This tiny .Net extension component uses a 3rd party web site, (https://checkip.dyndns.org/) to return the IP address of the Front End server the component is running on. This is the IP address seen by other servers that you may be connecting to and is useful where connections to other services are managed by a whitelist of IP addresses. The component also uses the .Net DNS utilities to return the actual Machine Name of the server, (rather than localhost).
