I'd like to include another tool often overlooked.
Propecia http://packetstormsecurity.org/UNIX/scanners/propecia.c
Usage: propecia x.x.x port
#propecia 192.168.0 21
192.168.0.100
192.168.0.200
192.168.0.201
Propecia is extremely fast for scanning class C addresses, and very low
noise.

Subject: how to find out a list of available ftp servers on LAN
I am using following command :-
nmap -n -P0 -p 21 -oG ftpLog.gnmap -iL IPs.txt
Are their other better options? or improvements to above command?
It takes around 7 mins to scan a list of 8960 IPs. Its ok, but I am still
looking for faster options.
