I mean redact/anonymise/mask/obfuscate the latter parts of any IPv6 addresses or MAC's for privacy.
If you have below output as an example:

$ ip -br -6 address
lo               UNKNOWN        ::1/128
eth0             UP             fe80::216:3ffe:aa33:8692/64

You could redact like below before posting here:

$ ip -br -6 address
lo               UNKNOWN        ::1/128
eth0             UP             fe80::XXXX/64

Most of the times we're only interested in the IPv6 prefix and mask anyway (above fe80: and /64):

Or for MAC addresses:

$ ip -br -6 link
lo               UNKNOWN        00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
eth0             UP             00:16:3e:98:33:21 <BROADCAST,MULTICAST,UP,LOWER_UP>

Into:

$ ip -br -6 link
lo               UNKNOWN        00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
eth0             UP             00:16:3e:XX:XX:XX <BROADCAST,MULTICAST,UP,LOWER_UP>

But for now, you should focus on below:

grosJambon33000:

    Serveurs DNS configurés via DHCP :     fec0:0:0:ffff::1%1
                                           fec0:0:0:ffff::2%1
                                           fec0:0:0:ffff::3%1

If that Windows PC is configured with the router IPv6 DNS address, you can assume the other network clients have them as well.
And most implementations prefer IPv6 over IPv4 DNS.
