Name	Data Type	Description
IPAddressString	String	Holds the TCP/IP Address value after a call to HostNameExists() or LookupHostName(). Until those methods are called (and if they FAIL) the value will be an empty string ("")

Method:	HostNameExists(strHostName)
Paramters:	1: strHostName (String) - The name of the network object you would like to look up.
Return Value:	Boolean

Method:	LookUpHostName(strHostName)
Paramters:	1: strHostName (String) - The name of the network object you would like to look up.
Return Value:	String
Description:	Attempts to determine if a network object named strHostName can be detected on your network and if so it returns the TCP/IP address, if not it returns an empty string ("") PROGRAMMING NOTE: On success IPAddressString will also contain the TCP/IP Address of strHostName.

This object class uses our standard HL7PlusException Class interface for error handling wherever possible.

Class Name:	HL7PlusDNSLookUp
