The Spread of the Witty Worm - CAIDA : ANALYSIS : security : witty: "Network Telescope

The UCSD Network Telescope consists of a large piece of globally announced IPv4 address space. The telescope contains almost no legitimate hosts, so inbound traffic to nonexistent machines is always anomalous in some way. Because the network telescope contains approximately 1/256th of all IPv4 addresses, we receive roughly one out of every 256 packets sent by an Internet worm with an unbiased random number generator. Because we are uniquely situated to receive traffic from every worm-infected host, we provide a global view of the spread of Internet worms."
