You might also want to manage expectations. Pentesting a full class A, even given low population of the network will take you months. I think
It can be done faster. Once upon a time I built a system with primarily shell/python/perl which used nmap and nbtscan to scan all RFC1918 addresses in a large company. With a LOT of timing optimization options, and a very focused set of ports we were scanning for, we were able to scan this many IPs in 2-3 days. However, we had to distribute the scan across 8 linux machines, each of which ran 4 scanning threads in parallel. We didn't utilize any broadcasts, of course. It is a pain, and I don't recommend doing it unless you have a good reason, but it can be done with enough effort. The more recent versions of nmap supposedly has a more efficient scanning engine. Definately use the newest stuff. tim ps- Our scanning network could scan 300+ IPs/sec on average (majority of IPs didn't have hosts, of course) and during the scan, a few older firewalls tipped over. Be careful.
