 .SH "HOST DISCOVERY"
 .PP
 One of the very first steps in any network reconnaissance mission is to reduce a (sometimes huge) set of IP ranges into a list of active or interesting hosts\&. Scanning every port of every single IP address is slow and usually unnecessary\&. Of course what makes a host interesting depends greatly on the scan purposes\&. Network administrators may only be interested in hosts running a certain service, while security auditors may care about every single device with an IP address\&. An administrator may be comfortable using just an ICMP ping to locate hosts on his internal network, while an external penetration tester may use a diverse set of dozens of probes in an attempt to evade firewall restrictions\&.

 .sp
 Traceroute works by sending packets with a low TTL (time\-to\-live) in an attempt to elicit ICMP Time Exceeded messages from intermediate hops between the scanner and the target host\&. Standard traceroute implementations start with a TTL of 1 and increment the TTL until the destination host is reached\&. Nmap\*(Aqs traceroute starts with a high TTL and then decrements the TTL until it reaches zero\&. Doing it backwards lets Nmap employ clever caching algorithms to speed up traces over multiple hosts\&. On average Nmap sends 5\(en10 fewer packets per host, depending on network conditions\&. If a single subnet is being scanned (i\&.e\&. 192\&.168\&.0\&.0/24) Nmap may only have to send two packets to most hosts\&.
