Re: MAP-E

This is not surprising to me as Dlink was one of my co-authors for RFC8585 ... and they indicated in v6ops that 
implementing CLAT was really easy. I guess they need to improve the GUI, etc.

Note that with 464XLAT, you still need the NAT64 at the ISP side, and also, the traceroutes will shows something weird, 
so not trustable unless you understand very well how it works. However, testing a web site or other services will work 
fine.

    I know this is 464XLAT rather than MAP-E that was originally requested, but recent versions of D-Link firmware, eg 
for the DVA-2800, include the CLAT functionality. My testing in November last year showed that it only partially 
worked, with the traceroutes to 64:ff9b::1.1.1.1 working, but it would not automatically translate a traceroute to 
1.1.1.1 to the IPv6 version. There have been a few new revisions since then and it is on my to-do list to re-test 
things, but I haven't had the time. 
    
    It is also worth noting that, in the original firmware revision I tested, I had to manually enter the URL for the 
CLAT configuration screen. It simply wasn't on the menu. On another version, it had a link to DS-Lite configuration, 
and from there you get a link to the CLAT options. It is possible that other devices and/or vendors also have this 
option, or options for similar technologies such as MAP-E, but they just don't have a link to it in the interface.

    If IP address sharing by blocks of ports becomes common and there is typical block size (say, 1024), blacklisting 
will be done block-wise.
