Windows NT (includes
Windows 10 Mobile, and Xbox One onwards)		 5.1 (XP) Yes No Add-on[9] No Windows XP users can use Dibbler, an open source DHCPv6 implementation. --update: Windows XP fully supports IPv6- but NOT IPv6 DNS queries (nslookup)[30]
6.x (Vista, 7, 8, 8.1), 10 RTM-Anniversary Update Yes[31] Yes Yes[9] No dnssd-win32 provides an open source implementation of ND RDNSS[32]
10 Creators Update and later Yes[31] Yes Yes[9] Yes Windows 10 Creators Update introduces support for RFC 8106 (6106) RDNSS.

Windows Phone 7.5 No No No No
8(.1)[34] Yes Yes Yes No Private lab research. No privacy extensions (RFC4941).
z/OS V1R4.0 Yes Yes No[35]  ?

z/VSE V4R2 Add-on[37] No  ?  ? Via a third party TCP/IP stack, IP6/VSE from Barnard Software, Inc.

Notes
  • Operating systems that support neither DHCPv6 nor SLAAC cannot automatically configure unicast IPv6 addresses.
  • Operating systems that support neither DHCPv6 nor ND RDNSS cannot automatically configure name servers in an IPv6-only environment.
