   Hello Tommi,   
      
   On Friday March 26 2021 17:57, you wrote to me:   
      
    TK> From my memory... Or imagination... I think you have announced it once   
    TK> in some testings in the past? If not, a good guess. :D   
      
   Probably...   
      
    TK>>> That happens because Radius resolves the hostname and uses the   
    TK>>> ipv4 address, even when connecting via proxy.   
      
   So Radius /only/ passes the IPv4 address to the proxy and the proxy has no way   
   to match that to an IPv6 address all by itself.   
      
   Coming to think of it: I have used a proxy server in the past. That was a long   
   time ago. In the time of dial up internet via POTS. The machine with the modem   
   (Win95) ran the proxy server so that other machines on the LAN could surf...    
   That was way before I even knew about IPv6.   
      
    MV>> 2) So this manual override works only for my node and to connect   
    MV>> to another node you have to make another override? IOW manually   
    MV>> enter a new line in the config for each node that is to be   
    MV>> connected via IPv6?   
      
    TK> Pretty much so when the node has also IPv4 address. But using an   
    TK> ipv6-capable proxy with Radius makes it possible to connect IPv6-only   
    TK> nodes too. :)   
      
   Presently there are only two nodes with the INO4 flag in the nodelist. Much   
   less then I expected. I had expected providers would massively convert their   
   customers to DS-Lite and at one time it seemed to happen. And then the tide   
   turned, most IPv6 capable customers have full Dual Stack. I do not know of one   
   single Fidonet system that is on a DS-Lite connection. That is for "fixed"   
   connections. Mobile is another story.   
      
   So yes, Radius can be tricked into connecting to IPv6 only nodes. But each   
   node must be individually configured. With only two this is doable...   
      
   So binkd has extra code to run with a HTTP style proxy and it passes the host   
   name to the proxy so that the proxy can do the resolving. There is of course   
   another significant difference between binkd and Radius. With Radius the   
   limitation is in the application itself. With binkd OS/2 the limitation is in   
   the OS. I suppose that in the hypothetical event OS/2 is updated to support   
   IPV6, the OS/2 version of binkd just needs a recompile to also support IPv6...   
      
      
   Cheers, Michiel
