IPv6 Pycharm for connection SFTP, FTP

1. Open Help | Edit Custom VM Options
2. Add

   -Djava.net.preferIPv6Addresses=true

   in it.

   You may also want to delete

   -Djava.net.preferIPv4Stack=true

   but I’m not sure whether it matters.

   

3. Restart Pycharm.
4.  Add SFTP IPv6 host. Example [2016:470:6d:10:1e11:19a1:bedd:d2e1]
