Hello good day!!!
I wanted to ask you what is the correct way to configure the dns for ipv6 in my Mikrotik RB750GR3.
My ISP provides ipv6 natively, I get a / 64 prefix and I connect my devices by SLAAC … In my DHCPV6 client configuration I omit the dns of my provider since I use the Cloudflare dns.
My query is if I have to put in IP / DNS the 4 dns of cloudflare (the 2 ipv4 and the 2 ipv6) ???
How does the mikrotik handle this ???
Greetings and thanks!!!
If you have dual-stack clients, you don’t really need to worry about IPv6 DNS resolvers, because IPv4 ones will work for AAAA queries just fine.
If you want to give IPv6 resolvers to clients, you need to decide if you want them to use DNS cache on router (scenario a), or bypass it and go to remote resolvers directly (scenario b). In RouterOS, IPv6 DNS config is still rough. By default, system just takes IPv6 resolvers from “/ip dns” and gives them to clients, i.e. scenario b. It’s for both radvd and stateless DHCPv6. If you want scenario a, you have to manually override DHCPv6 option, and there’s currently no way to do anything with radvd.
And don’t double post!
