Guten Tag Okabayashi, Hirotsugu,

What does this mean? You can only map IP addresses to host names in
this file. Does the host name of NAT64 map to the IP address of your
SVN server or does NAT64 host name map to IP address of NAT64 host and
you're accessing NAT64 as SVN server in Tortoise? Please post the
relevant line in hosts file and the URL you use in Tortoise to access
your repo with explanation of which host name resolves to which IP.

Why should that be necessary in general? Your SVN server is IPv4 only,
why should the IPv4 capable Windows 7 should access it using NAT64?
If you want to use IPv6 with your Windows 7, make you SVN server
available using IPv6. I don't understand what's the purpose of NAT64
in your scenario as "the server side" is SVN Server and is not capable
of IPv6. Does your NAT64 translate IPv4 from Windows 7 to IPv6
internally, just to translate it back to IPv4 again externally to
communicate with SVN Server?

It would only make sense to use NAT64 to translate between your SVN
server and AD, because Windows 7 can communicate with AD directly
using IPv6, but SVN Server can't. Therefore I would suggest changing
your hosts file on the Windows 7 client to remove whatever you map to
NAT64 and let SVN Server and Windows Client communicate directly.
Afterwards you need to make SVN Server IPv6 aware or AD IPv4 or both
simply dual stack, which would be what I would do in your case as dual
stack is and will be common and standard for years. NAT64 seems to
only complicating things unnecessarily.

From your description I don't think there's something wrong with
Tortoise or Subversion, but with your network. But my experience with
IPv6 is limited...

Mit freundlichen Grüßen,
