> Some issues were reported on dev/user list that may be caused by ipv6 usage. I am not sure if Ignite can properly work with ipv6 networks. This needs to be tested and another issue has been filed - https://issues.apache.org/jira/browse/IGNITE-6503.
> For now it seems to be pretty handy just to have warning on node start:

> Please set system property '-Djava.net.preferIPv4Stack=true' to avoid possible problems in mixed environments.
