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 4.2 (Ice Cream Sandwich) Yes[1][2] Yes No[3] Yes
ChromeOS 67.0.3396.99 Yes Yes No Yes
Cisco IOS 15.3 Yes Yes Yes Yes[4] Support for RDNSS option as of 15.4(1)T, 15.3(2)S.
Cisco Meraki MR series 28.1 and later Yes Yes No Yes Devices support DHCPv6 for clients but not for themselves.[5]
MX & MX series No No No No Devices can only carry/pass through IPv6 on bridge, but not route.[6]
Debian 3.0 (woody) Yes Yes Yes Yes RDNSS support with "rdnssd" and "resolvconf" or "openresolve" packages.
Fedora 13 Yes Yes[7] Yes[7] Yes[7]
FreeBSD 9.0 Yes[8] Yes Add-on[9] Yes[10]
HP-UX 11i Yes Yes Yes Yes [11]
IBM i 7.1 Yes Yes Yes No [12]
iOS 4.1 Yes Yes Yes Yes[13]
Juniper JUNOS 14.1 Yes Yes Yes Yes RDNSS support introduced in JunOS 14.1[14]
LibreELEC 9.2.1 Yes Yes Yes Yes
Mageia 7+ Yes Yes Yes Yes Mageia has had full support for IPv6 only and IPv4 + IPv6 since Mageia 7, as well as continuing to support IPv4 only systems.[15]
macOS Mac OS X 10.7 (Lion) Yes Yes Yes[16] Yes[17] Versions 10.7 through 10.10 often prefer IPv4 even when working IPv6 connectivity is available.[18] Versions 10.11 and up will prioritize IPv6 Traffic in spec with Happy Eyeballs.[19]
MeeGo 1.2 No[20] Yes[21] No Yes[22]
NetBSD 7.0 Yes Yes Yes Yes
OpenBSD 6.6 Yes Yes Add-on[9] Yes RDNSS is only supported for rad(8) so far. As of 6.6, OpenBSD still does not favor IPv6 connectivity if there is IPv4 connectivity.[citation needed]
openSUSE 42.1 (Leap) Yes[23] Yes Yes Yes
OpenVMS 8.3 Yes Yes No No
ReactOS 0.4.11 No No No No Though ReactOS itself has no IPv6 support, ReactOS Foundation services are all IPv6 enabled.
Red Hat Enterprise Linux 6 Yes[24] Yes Yes[9] Yes
Solaris 11 Yes Yes Yes Yes[25]
SUSE Linux Enterprise Server 11 Yes[26] Yes Yes Yes
Symbian 7.0 Yes Yes No No [1][permanent dead link]
Ubuntu All supported versions 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 [27]
Windows NT (includes
Windows 10 Mobile)
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)[28]
6.x (Vista, 7, 8, 8.1), 10 RTM-Anniversary Update Yes[29] Yes Yes[9] No dnssd-win32 provides an open source implementation of ND RDNSS[30]
10 Creators Update and later Yes[29] Yes Yes[9] Yes Windows 10 Creators Update introduces support for RFC 8106 (6106) RDNSS.
11 ? Yes ? ? Not yet enough information of any changes.
Windows Mobile 6.5 Yes Yes Lite[31] 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
8(.1)[32] Yes Yes Yes No Private lab research. No privacy extensions (RFC4941).
z/OS V1R4.0 Yes Yes No[33] ?
z/VM V5R1.0 Yes Yes No No [34]
z/VSE V4R2 Add-on[35] 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.
