What port does Nmap use?

By default, Nmap scans the most common 1,000 ports for each protocol. This option specifies which ports you want to scan and overrides the default. Individual port numbers are OK, as are ranges separated by a hyphen (e.g. 1-1023 ). The beginning and/or end values of a range may be omitted, causing Nmap to use 1 and 65535, respectively.
