1) Haven't really checked, but... 2) I have a fixed IPv4 address, and a dynamic IPv6. So far the latter also seems to be fairly stable, and I host my webpages on both IPv4 and IPv6 these days. My server is a ThinkPad X240 with VMware ESXi which in turn host Ubuntu for SSH, Web, etc... And a Pi-hole VM just to block the "wost" of the internet.
