The Network Mapper - result compare utility
Ndiff is a tool to aid in the comparison of Nmap scans. It takes two Nmap XML output files and prints the differences between them them: hosts coming up and down, ports becoming open or closed, and things like that. It can produce output in human-readable text or machine-readable XML formats.

Nmap scans
nmap
Nmap is a utility for network exploration or security auditing.
It supports ping scanning (determine which hosts are up), many port scanning techniques (determine what services the hosts are offering), and TCP/IP fingerprinting (remote host operating system identification). Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, reverse-identd scanning, and more. In addition to the classic command-line nmap executable, the Nmap suite includes a flexible data transfer, redirection, and debugging tool (netcat utility ncat), a utility for comparing scan results (ndiff), and a packet generation and response analysis tool (nping).
