Template:SHORTDESC:

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 4.1 (Jelly Bean) Yes[1][2] Yes No[3] Yes DHCPv6-PD (Prefix delegation only) support provided for Android 11 and newer will be available at the end of 2025 via a Google Play System Update.[4]

Cisco IOS 15.3 Yes Yes Yes Yes[5] 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.[6]
MX & MX series No No No No Devices can only carry/pass through IPv6 on bridge, but not route.[7]
Debian 3.0 (woody) Yes Yes Yes Yes RDNSS support with "rdnssd" and "resolvconf" or "openresolve" packages.
Fedora 13 Yes Yes[8] Yes[8] Yes[8]
FreeBSD 9.0 Yes[9] Yes Add-on[10] Yes[11]

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.[16]
macOS Mac OS X 10.7 (Lion) Yes Yes Yes[17] Yes[18] Versions 10.7 through 10.10 often prefer IPv4 even when working IPv6 connectivity is available.[19] Versions 10.11 and up will prioritize IPv6 Traffic in spec with Happy Eyeballs.[20]

NetBSD 7.0 Yes Yes Yes Yes
Nintendo Switch 17.0.1 No No No No
Switch 2 20.1.5 Yes Yes ? ?
OpenBSD 6.6 Yes Yes Add-on[10] 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[24] Yes Yes Yes
OpenVMS 8.3 Yes Yes No No
PlayStation 4 v3.50 No No Yes[25] ?
5 Yes Yes Yes ?

Red Hat Enterprise Linux 6 Yes[26] Yes Yes[10] Yes
Solaris 11 Yes Yes Yes Yes[27]
SUSE Linux Enterprise Server 11 Yes[28] Yes Yes Yes
Symbian 7.0 Yes Yes No No [1][permanent dead link]
Tizen (Smart TVs) 1420.0 Yes Yes ? ? [29]
1622.4 Yes Yes ? ?
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 [30]
Windows NT (includes
Windows 10 Mobile, and Xbox One onwards)
5.1 (XP) Yes No Add-on[10] No Windows XP users can use Dibbler, an open source DHCPv6 implementation. --update: Windows XP fully supports IPv6- but NOT IPv6 DNS queries (nslookup)[31]
6.x (Vista, 7, 8, 8.1), 10 RTM-Anniversary Update Yes[32] Yes Yes[10] No rdnssd-win32 provides an open source implementation of ND RDNSS[33]
10 Creators Update and later Yes[32] Yes Yes[10] Yes Windows 10 Creators Update introduces support for RFC 8106 (6106) RDNSS.
Windows Mobile 6.5 Yes Yes Lite[34] 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)[35] Yes Yes Yes No Private lab research. No privacy extensions (RFC4941).
z/OS V1R4.0 Yes Yes No[36] ?
z/VM V5R1.0 Yes Yes No No [37]
z/VSE V4R2 Add-on[38] No ? ? Via a third party TCP/IP stack, IP6/VSE from Barnard Software, Inc.

Notes

[edit | edit source]
  • 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.
