Bare in mind, a lot of them might be multiple IPs per server, a test I
ran a few days ago, on just one range, from four random members of this
list alone gave me some scary results, a few telnet's did however
confirm my suspicions, so in reality it may be far less, but there are
still enough, but seeing as how likes of google think its cool to run
open resolvers, maybe its why half these admins might not know any
