IPv6 Connectivity of vSphere Features
Certain vSphere features do not support IPv6:
n
vSphere DPM over Intelligent Platform Management Interface (IPMI) and Hewlett-Packard Integrated
Lights-Out (iLO). vSphere 6.5 supports only Wake-On-LAN (WOL) to bring a host out of standby
mode.
n
vSAN
n
Authentication Proxy
n
Use NFS 4.1 with AUTH_SYS.
n
vSphere Management Assistant and vSphere Command-Line Interface connected to Active Directory.
Use LDAP to connect the vSphere Management Assistant or the vSphere Command-Line Interface to
the Active Directory database.
