Nmap scan report for scanme.nmap.org (50.7.87.82)
Host is up (0.13s latency).
Other addresses for scanme.nmap.org (not scanned): 88.99.249.74 188.40.181.48 50.7.85.220 178.63.240.96 188.40.181.49 69.197.146.178 188.40.181.51 50.7.87.83 178.63.240.97 69.197.146.179 50.7.87.84 69.197.138.83 204.12.192.218 188.40.181.50 50.7.85.219 69.197.138.82 50.7.85.218 204.12.192.219 50.7.85.221 50.7.87.86 50.7.85.222 50.7.87.85

443/tcp   open     https
5810/tcp  open     unknown
8888/tcp  open     sun-answerbook
9100/tcp  open     jetdirect
49152/tcp filtered unknown

Nmap done: 1 IP address (1 host up) scanned in 29.59 seconds

What happens internally

• DNS resolution → IP address

• Default scan:

  • Host discovery

  • Top 1000 TCP ports

  • SYN scan (if run as root)
