+(Note that version 3.80 is really 3.8, but released after 3.79.)
+
+LFT, short for Layer Four Traceroute, is a sort of 'traceroute' that often
+works much faster (than the commonly-used Van Jacobson method) and goes through
+many configurations of packet-filters (firewalls). More importantly, LFT
+implements numerous other features including AS number lookups through several
+reliable sources, loose source routing, netblock name lookups, et al. What
+makes LFT unique? LFT is the all-in-one traceroute tool because it can launch a
+variety of different probes using ICMP, UDP, and TCP protocols, or the RFC1393
+trace method. For example, rather than only launching UDP probes in an attempt
+to elicit ICMP "TTL exceeded" from hosts in the path, LFT can send TCP SYN or
+FIN probes to target arbitrary services. Then, LFT listens for "TTL exceeded"
+messages, TCP RST (reset), and various other interesting heuristics from
+firewalls or other gateways in the path. LFT also distinguishes between
+TCP-based protocols (source and destination), which make its statistics
+slightly more realistic, and gives a savvy user the ability to trace protocol
+routes, not just layer-3 (IP) hops. With LFT's verbose output, much can be
+discovered about a target network.
+
+WhoB is a likable whois client (see whois(1)) designed to provide everything a
+network engineer needs to know about a routed IP address by typing one line and
+reading one line. But even so, it's worth typing a few more lines because WhoB
+can do lots of other cool things for you! It can display the origin-ASN based
+on the global routing table at that time (according to Prefix WhoIs, RIPE NCC,
+or Cymru), the 'origin' ASN registered in the RADB (IRR), the netname and
+orgname, etc. By querying pWhoIs, WhoB can even show you all prefixes being
+announced by a specific Origin-ASN. WhoB performs the lookups quickly, the
+output is easily parsed by automated programs, and it's included as part of the
+Layer Four Traceroute (LFT) software package. LFT uses WhoB as a framework (and
+you can too, quite easily--see whois.h). Recent LFT releases (as of version
+2.5) include WhoB functionality through a standalone "whob" client/command
+placed in the LFT binary directory. 
+
+ LFT and WhoB continue to evolve and provide more and more useful data to
+ network engineers and to anyone else that cares how IP datagrams are being
+ routed. With the advent of smarter firewalls, traffic engineering, QoS, and
+ per-protocol packet forwarding, LFT and WhoB have become invaluable tools for
+ many network managers worldwide.
