ABSTRACT
IP address ending with .0 or .255. For each PING sent, they expected one PING REPLY in return. And for
each network that replied with more than one packet, they counted the number of replies and put the
data into a database. All networks that did reply with more than one packet for each packet sent were
considered to be an amplifier network. After pinging the entire Internet (more or less), they published on
their Web site a list of the 1024 worst networks, including the e-mail address for the person responsible
for the IP address and its associated network. The worst networks were those networks that gave them the
highest number of replies to a single PING, or the best amplification effect.
