@falken I used to have a separate IP that did SSH on 443 (and IPoDNS), but it's been mostly unnecessary for some time and the extra IP started to cost so I dropped it. Not entirely convinced about any of the 443 proxy stuff I've seen, given an existing busy webserver.
@noodles my ISP (the awesome #zeninternet ) gives me a small IPv4 block for free, and I've never done much with it. Better to setup and not need than the reverse I think
