Hello Alex,

I just looked at pymonetdb source code and indeed it does not support
IPv6 yet. I'm going to create an issue to request for it. The reason is
because in the past, the MAPI protocol (which MonetDB uses for socket
connections) didn't support IPv6, so the clients (Python, Ruby, JDBC,
etc.) never had to implemented them. However they can now add this option.

Best regards,

Pedro

Hai Kalai,

I?m not sure, but this feels like MonetDB wasn?t properly installed?  How did you install it?

Jennie
