Next time your DNS server is having IPv6 problems, make sure to verify that the AAAA batteries don't need to be replaced. (also TIL these are a thing)

I'm pretty new with it, but I only hear a few garbled checks on the 10-10 daily net on 28.380. On top of that I'm not 100% confident in my whole setup.

It's not hard to use. It's just different. It's easy to learn. Just adding a bunch of octets to the v4 header is going to have to get implemented in hardware and software somewhere. You think migration for v6 is long...

Why use ULA? Can you not get GUA from your provider? Unless this is a v6 only system you may end up with unexpected behavior with the prefix policy table. See here: datatracker.ietf.org/doc/draft-ie...

What i mean it's misleading to say one is better than the other. It's like saying Leaded vs. Unleaded Gasoline: which is better? There may be some positive things with IPv4, but we shouldn't be counting on them because it's going away.

It's not one or the other. IPv4 is a legacy protocol that IPv6 is going to replace. The IETF has designated it as such. And also you may be using old information, as IPsec is not mandatory for IPv6. See RFC 8200, etc.

IPv6 isn't as intimidating as it once was for apps. Consider implementing both protocols. You can learn when you inevitably have to make a change. There are organizations going IPv6 only (see US govt). Most of the major cloud providers have mostly implemented parity in the protocols.
