IPv6 support for mIRC (fka mircv6loader)


When you load this dll in mIRC, you can connect to IPv6. It should work better than any tunnel/proxy.
It support SSL and has the ability to reply to IPv6 ident requests.

As you can see, the identd works over IPv6 (“”), and SSL over IPv6 also works.

How to use

Make mIRC load the dll BEFORE you connect to anything.
This can be done by placing "on 1:START:/dll mircv6.dll mircv6 0" in your remote.
Some extra settings are explained in the readme.txt.

How it works (worked)

I wrote a small article about it.


I made this loader for private use only. But since alot of people need IPv6 support for mIRC, I made it public.
Use it at your own risk, since there might be some (legal) issues.

Known issues

  • When dccserver is enabled, mIRC crashes while exiting. This is because mIRC first unload the dll and then closes the dccsocket, resulting in a bad call. You can 'fix' it by disabling the dccserver before exiting (using on EXIT or so). Should be fixed.


  • enable mirc scripting sockets to listen on IPv6 addresses (but will prolly never happen)

  • fix crash-on-exit-with-dccserver-on issue (status: still too lazy :p) (status: lazy again)


If you found a bug or if you are having a real hard time getting it to work, you can contact me at davyhollevoet[]hotmail[]com. And please, no n00b questions.
