Unfortunately, amazingly, Android still does not support DHCPv6 so that you can take advantage of it. http://www.techrepublic.com/article/androids-lack-of-dhcpv

is this even an issue? dnsmasq(which most routers use) for example supports both.

  Yes, it's an issue. My router cannot assign an IPv6 address to my phone if my phone can't ask for one.

    If you really want IPv6 to work, enable SLAAC.
    - jeff_marshall 10y ago
      How are you getting DNS configuration (server + search domain) via SLAAC?

        With the RDNSS + DNSSL options for Router Advertisement (RFC standard since 2010), described here: https://tools.ietf.org/html/rfc6106#section-5 https://tools.ietf.org/html/rfc6106#section-5 If you know a RA implementation that does not support this, please tell.

        Or IPv4 DHCP, if you're not IPv6-only.

        You might not want to rely on a soon to be declared historic protocol for essential network configuration... https://tools.ietf.org/html/draft-howard-sunset4-v4historic-00 https://tools.ietf.org/html/draft-howard-sunset4-v4historic-...

        well, at least as recently as Windows 8.1[1], windows was on that list and microsoft said to use DHCP for that (which has always bugged me as it's yet another protocol to support). Have things changed? I haven't checked on win 10.

DHCPv6 is just a secondary mechanism with IPV6 though, meant primarily for networks where the IT dept does fancy things with DHCP and want to keep doing it with IPv6.
