This is a comparison of operating systems in regard to their support of the IPv6 protocol.

OS Version Claimed IPv6-ready Installed by default DHCPv6 ND RDNSS Notes
AIX 4.3 Yes Yes Yes No
AlliedWare Plus 5.4.4 Yes Yes Yes No
Android 5.0 (Lollipop) Yes[1][2] Yes No[3] Yes Supports ND-RDNSS in Android 5.0 and above. Does not support DHCPv6.[3] Suffers from intermittent loss of its unicast address on some phones.[4]
Cisco IOS 15.3 Yes Yes Yes Yes[5] Support for RDNSS option as of 15.4(1)T, 15.3(2)S.
Debian 3.0 (woody) Yes Yes Yes Yes RDNSS support with "rdnssd" and "resolvconf" or "openresolve" packages.
Fedora 13 Yes Yes[6] Yes[6] Yes[6]
FreeBSD 9.0 Yes[7] Yes Addon[8] Yes[9]
HP-UX 11i Yes Yes Yes Yes [10]
IBM i 7.1 Yes Yes Yes No [11]
iOS 4.1 Yes Yes Yes Yes[12] iOS supports stateless DHCPv6 since version 4 and stateful DHCPv6 since 4.3.1.
Juniper JUNOS 14.1 Yes Yes Yes Yes RDNSS support introduced in JUNOS 14.1[13]
macOS Mac OS X 10.7 (Lion) Yes Yes Yes[14] Yes[15] Versions 10.7 through 10.10 often prefer IPv4 even when working IPv6 connectivity is available.[16] Versions 10.11 and up will prioritize IPV6 Traffic in spec with Happy Eyeballs.[17]
MeeGo 1.2 No[18] Yes[19] No Yes[20]
NetBSD 7.0 Yes Yes Yes Yes
OpenBSD 5.2 Yes Yes Addon[8] Yes RDNSS is only supported for rtadvd so far.
openSUSE 42.1 (Leap) Yes[21] Yes Yes Yes openSUSE Leap 42.1 is a hybrid distribution using source code from SUSE Linux Enterprise 12 Service Pack 1.
OpenVMS 8.3 Yes Yes No No
Red Hat Enterprise Linux 6 Yes[22] Yes Yes[8] Yes
Solaris 10 Yes Yes Yes No
SUSE Linux Enterprise Server 11 Yes[23] Yes Yes Yes
Symbian 7.0 Yes Yes No No [2]
Ubuntu 11.04 to 13.10 Yes Yes Yes Yes RDNSS support available so long as NetworkManager uses IPv6 "Automatic" setting, otherwise "rdnssd" package required.
webOS 2.1.0 No No No No [24]
Windows NT [includes
Windows 10 Mobile]
5.1 (XP) Yes No Addon[8] No Windows XP users can use Dibbler, an open source DHCPv6 implementation.--update: windows xp fully supports ipv- but NOT ipv6 DNS queries (nslookup)[25]
6.X (Vista), 7, 8, 8.1, 10 Yes[26] Yes Yes[8] Yes Windows 10 Creators Update introduces support for RFC 8106 (6106) RDNSS. For earlier versions dnssd-win32 provides an open source implementation of ND RDNSS[27]
Windows Mobile 6.5 Yes Yes Lite[28] No If the OEM explicitly unsets the SYSGEN_TCPIP6 pre-processor symbol, the built image will not have any IPv6 capabilities.
Windows Phone 7.5 No No No No Windows Phone 8 might have some support.[29]
8(.1)[30] Yes Yes Yes No Private lab research. No privacy extensions (RFC4941).
z/OS V1R4.0 Yes Yes No[31]
z/VM V5R1.0 Yes Yes No No [32]
z/VSE V4R2 Addon[33] No Via a third party TCP/IP stack, IP6/VSE from Barnard Software, Inc.


  • 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.
