Hi, I'm hoping someone can tell me whether it is possible to set the IPv6 DNS server on a Spark HG659b. It was easy enough to set the IPv4 DNS server under the DHCP settings of the router but I'm having trouble with the IPv6 DNS server. This is what the settings look like for the IPv6 DHCP server section but I'm unsure on what to put in the prefix section. 



Also I'm confused because it says IPv4 DNS server in this section? Do I just put an IPv6 address in this field? Or is it just not possible to set IPv6 DNS on this router?


Thanks :)

I know nothing about the HG659b, but just looking at the options on that config page, I would think what you need to do is to select something other than the "manual" option.  For IPv6, your ISP will be delegating you a block of real IPv6 addresses, each of which is able to be accessed from the rest of the Internet.  The block is usually a /48 (if you are lucky), a /56 or a /64.  You need to tell your DHCPv6 setup to take one /64 block of the delegated addresses and use them to assign to your devices.  But before that, you really need to check that the router's IPv6 firewall has been set up so that incoming connections can not be made to all your devices, as without that, they will be open to direct connections from the Internet.  With IPv4, you only get one assigned IPv4 address that is able to talk to the wider Internet and all your devices get local IP addresses that can only connect to the Internet using the NAT feature of your router.  The need to do NAT keeps your devices fairly safe as it provides a natural firewall.  With IPv6, all the devices get real IPv6 addresss, and there is no NAT protecting them.  And a lot of the routers I have seen do NOT automatically set up the IPv6 firewall to protect them - you have to do that.

mcraenz: Are you with Spark? Do they do ipv6? What are you wanting to achieve?


I have setup a Raspberry Pi to run pihole and I've set it as my DNS server (in the IPv4 DHCP section of my router) to block ads. It works on all my devices except my Windows desktop PC because rather than just using the IPv4 address of the Pihole it was using an IPv6 address as well. I have other options to make it work though e.g. I can just set the IPv6 address of the Pihole in my network settings on the desktop PC or at the moment I've just turned off the IPv6 DHCP section on my router. But I was just curious whether I was able to set it from the router itself as I would prefer that.
