Listed by order desc of needs :
-------------------------------
	* Modify DNS payload capture : think to malformed packets & packets containing IP options
	* Man page
	* Implement server version (chaos) and IXTR (both if possible -> check port 53 before all!)
	* DNS cache : could it be reinitialized ? icmp request when sending packet ?
	* Prediction DNS ID (see Zalewski algorithm and "vseq" soft)
		* Spoofing over internet (can it be done with *normal* connection, with birthday attack?)
		* Fingerprinting for server versions or client or OS (depending of the random implementation)
	* "DNS *collect servers* function : tries passivly and activly to obtain as much nameserver IP addresses as possible just from watching and reacting to local DNS traffic" [ from zodiac Project : http://www.team-teso.net/projects/zodiac/ TODO list ]
	* ncurses interface if enabled in autoconf (./configure with --enable-ncurses option)
