> {{OzoneSecurityUtil#getValidInetsForCurrentHost}} performs hostname lookup for all local network interfaces, even for invalid addresses. This significantly slows down some secure tests ({{TestHddsSecureDatanodeInit}}, {{TestSecureOzoneCluster}}) when run on a machine with special IPv6 network interfaces due to timeout reaching IPv6 DNS servers.
> This issue proposes to disable the lookup for invalid addresses.
