Tim, Thanks for your thoughts. But I think you just got that slightly wrong: Am Fri, 04 Oct 2019 schrieb Tim Chown:
I think it boils down to a) deploy IPv6 where it makes sense for you to do so. b) remove IPv4 where it makes sense for you to do so.
Let me correct that for you: a) deploy IPv6 everywhere. Otherwise you are not reaching the whole internet. There are networks out there, which you are currently missing. If you think otherwise, drop me a note at bbu@penguin.de b) Hide all your legacy cruft behind some layers of NAT or Dualstack Application Proxies, if it please you and remove IPv4 where it makes sense for you to do so. Cheers, Bjørn
