/***************************************************************************
* TargetGroup.h -- The "TargetGroup" class holds a group of IP addresses, *

* Nmap is generally free for end users to download and use themselves, *

* *
* The Nmap license generally prohibits companies from using and *

* this purpose. See https://nmap.org/oem/ *
* *
* If you have received a written Nmap license agreement or contract *

* choose to use and redistribute Nmap under those terms instead. *
* *
* The official Nmap Windows builds include the Npcap software *
* (https://npcap.com) for packet capture and transmission. It is under *
* separate license terms which forbid redistribution without special *

* Source is provided to this software because we believe users have a *

* This also allows you to audit the software for security holes. *
* *
* Source code also allows you to port Nmap to new platforms, fix bugs, *

* fund the project by selling licenses with various terms, and also *
* because the inability to relicense code has caused devastating *
* problems for other Free Software projects (such as KDE and NASM). *
