I just registered to find some answers that I could not find. Will post that in another topic.
To contribute I was searching for routerOs and SIIT support or plans/thoughts on it. In short, in datacenters, but also in customer enviroments (like the ones I manage) remove IPv4 from all servers and only service it on the edge. As I'm new to Mikrotik and still testing at home I was impressed by the capabilities of routerOs.
Hence this post to question/inform about this SIIT and maybe resulting from that new hardware and software designs that focus on IPv6 and IPv4 as a feature instead of Ipv4 as main driver for designs.
I have been running some dualstack enviroments, it's a lot more work therefore everything new I setup IPv6 only which causes some challenges but also simplifies so much.
