Hello,
I managed to get IPv6 working on my R7000 using Radvd and this my configuration:
I had do a custom Radvd config because otherwise my custom IPv6 DNS addresses wont get passed to the clients, due to some reason the ISP DNS server were always showing up on the network status of the devices connected.
My questions:
1. The devices connected are using 2620:74:1c::2:2 2001:470:20::2 for DNS queries, however the router itself it still using the ISP DNS servers, how can I make sure that the router also uses 2620:74:1c::2:2 2001:470:20::2?
Currently it looks like DNS over IPv6 only it not going anywhere:
Code:
dig -6 google.com AAAA
; <<>> DiG 9.11.2 <<>> -6 google.com AAAA
;; global options: +cmd
;; connection timed out; no servers could be reached
2. Better yet it it possible to set a static/predictable IPv6 for the router itself and pass that address to the clients and then force them to do IPv6 DNS resolution over the router too? And also make sure any request made inside the router also goes to the local DNS server using local IPv6...
Is my question that stupid? Am I the only one who wants the router itself to be able to be to ping/ding/wtv over IPv6? _________________ 1x Netgear R7800 (latest); 3x Netgear R7000 (latest); 2x Asus RT-N16 (v3.0-r47656); 2x Fonera 2100 (v3.0-r45454).
I want to know why we can't just hit enable and then apply for it to work like it did in the past, i don't want to configure a code for it to work.
That is a very good point indeed. _________________ 1x Netgear R7800 (latest); 3x Netgear R7000 (latest); 2x Asus RT-N16 (v3.0-r47656); 2x Fonera 2100 (v3.0-r45454).
The developer of Android decided that DHCP6 was not necessary to support.
Also, are you able to run "dig -6 google.com AAAA" in your router itself and get a result?

Is it reliable? How are you getting it? On ifconfig? _________________ 1x Netgear R7800 (latest); 3x Netgear R7000 (latest); 2x Asus RT-N16 (v3.0-r47656); 2x Fonera 2100 (v3.0-r45454).

If anyone is curious about this, see the Google issue tracker and the info (at the bottom) of this root app to add DHCPv6 (obviously not practical for most people). _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#
