Scanning IPv6 addresses


One of the most important updates of Nmap is its IPv6 support. All port scanning and host discovery techniques can take IPv6 addresses, including OS detection, and there are even some new interesting discovery techniques that address the problem of brute force scanning the IPv6 address space.

This recipe describes how to scan an IPv6 address with Nmap.

How to do it...

Open your terminal and type your desired Nmap command with the additional -6 option:

# nmap -6 <target>
# nmap -6 scanme.nmap.org
   Nmap scan report for scanme.nmap.org      
   (2600:3c01::f03c:91ff:fe18:bb2f) 
   Host is up (0.065s latency). 
   Other addresses for scanme.nmap.org (not scanned): 45.33.32.156 
   Not shown: 997 closed ports 
   PORT      STATE SERVICE 
   22/tcp    open  ssh 
   80/tcp    open  http 
   31337/tcp open  Elite  
   Nmap done: 1 IP address (1 host up) scanned in 1.20 seconds 

How it works...

The -6 option enables IPv6 scanning, which is one of the most important updates...
