Correct IPv6 address for NextDNS servers?
my.nextdns.io says my IPv6 resolvers are:
2a07:a8c0::<my config ID>
2a07:a8c1::<my config ID>
But the nextdns.io Setup Guide section for pfSense says the IPv6 resolvers are:
2a07:a8c0::
2a07:a8c1::
If I'm updating PFSense DNS servers in System > General Setup, which IPv6 addresses do I specify?

When you are lacking in knowledge department the logical thing to do is to follow the instructions. And the instructions are very clear for this:
«pfSense
1. Go to Services → DNS Resolver and on the tab General Settings scroll down to the Custom Options box.
2. Enter the following lines:
server:
forward-zone:
name: "."
forward-tls-upstream: yes
forward-addr:.. .dns1.nextdns.io
forward-addr:... .dns1.nextdns.io
forward-addr:.. .dns2.nextdns.io
forward-addr:... .dns2.nextdns.»So, copy-paste the whole thing, not just the IPv6.
The personalized IPv6 or IPv4 are for other scenarios where you don't have pfsense.

Those instructions are also for an older version of PFSense before you could use the GUI to enter the TLS hostname. You no longer need to use Custom Options:

The question remains: When updating DNS servers in System > General Setup, do I use a 4-octet IPv6 address or a 7-octet IPv6 address?
