Mapper is a network connectivity tester that employs a number of techniques to try and guess if a host is alive or not. Since many machines have ICMP firewalled off, it uses 7 different TCP and ICMP tests in attempting to gain some sort of response. Mapper can send spoofed decoys and use random delays for added stealth.
