Sitting pretty in IPv4 land? Look, you're gonna have to talk to IPv6 at some stage

How to juggle two smartly incompatible protocols

We can be forgiven for not having weaned ourselves onto IPv6 earlier. It's been around in draft form since late 1998, but was only released as a standard in July 2017 (that'll be RFC 8200). That this has finally happened, though, means we're being told more loudly than ever that we no longer have an excuse. So do we have one? Can we still stick with IPv4 if we want to?…
