•Bit 2 Set to 1 to disable all ISATAP-based interfaces. Default value is 0.
•Bit 3 Set to 1 to disable all Teredo-based interfaces. Default value is 0.
•Bit 4 Set to 1 to disable IPv6 over all non-tunnel interfaces, including LAN interfaces and Point-to-Point Protocol (PPP)-based interfaces. Default value is 0.
•Bit 5 Set to 1 to modify the default prefix policy table to prefer IPv4 to IPv6 when attempting connections. Default value is 0.
