Granted, each subsequently smaller subnet also limits the maximum number of hosts thatwill respondto the smurf trigger. The point is that, the web-site ONLYtests 0 and Actually, that's often not the case. Through NAT and other modern marvels, it's possible to have massively overpopulated netblocks that all respond. The largest amplifier we've found yet was 170,000x (on a class C).Thank you Troy, However my point remains.
Roeland, I believe that during the last run, netscan tested down to the /27 boundry. While I agree that this isn't as complete as testing down to the /30 boundry, even testing to the /24 boundry provides more information than not testing at all. Additionally, the website indicates that there will be another test down to the /27 boundry. --- John Fraizer EnterZone, Inc
