Hello all,<br>
<br>
I'm reading this thread with interest. Wasn't it frowned upon at
some point, to do such widespread network scanning using nmap, and
aren't some firewalls/software set-up to detect such network
scanning and block it automatically? In which case, results are
unlikely to show all devices.<br>
Kindest regards,<br>

First, happy to tell you hello.
Second, I just double checked the nmap network scannning and you are
right, it's supported now, when was added?. Actually if you google for
networking scanning IPv6 with nmap almost all pages mention it does not
exist. I have an old version of nmap with no support, I just install a
new one and guess what, it has the option:
nmap -6 -sP 2001:abcd:7002:4128:/64
Wow, what a horrible option, hahaha, in theory scanning a single /64
must be around 30 years.
Thanks for the update.
Alejandro,

<pre class="moz-quote-pre" wrap="">Hi Alejandro, all,
This is a side diversion, however, just FYI, nmap does indeed support
IPv6 just fine. However as pointed out, due to the sheer size of the
address space, it's not practical to use it to scan a prefix. But for
a detailed scan of a single host's ports/services, yes, you can use v6
with nmap.
Cheers,
Daniel
