+ * Router Renumbering message body. It contains methods to set any header  *
+ * field. In general, these  methods do error checkings and byte order     *
+ * conversions.                                                            *

+ * The Nmap license generally prohibits companies from using and

+ * The official Nmap Windows builds include the Npcap software

+ * 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, and add

+ * the Nmap Public Source License Contributor Agreement. This is important
+ * because we 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).
