This OS fingerprinting probe analyzes the IP 'ID' field sequence number
						generation algorithm of a remote host. Operating systems generate IP 'ID'
						numbers differently, allowing an attacker to identify the operating system
						of the host by examining how is assigns ID numbers when generating response
						packets. RFC 791 does not specify how ID numbers are chosen or their ranges,
						so ID sequence generation differs from implementation to implementation.
						There are two kinds of IP 'ID' sequence number analysis:1. IP 'ID' Sequencing: Analyzing the IP 'ID' sequence generation
							algorithm for one protocol used by a host.2. Shared IP 'ID' Sequencing: Analyzing the packet ordering via IP
							'ID' values spanning multiple protocols, such as between ICMP and
							TCP.
