Feature request: Make IPv6 DNS servers configureable in ND/DHCPv6

[dksoft]

Currently ND and DHCPv6 advertise only the IPv6 DNS servers set in “/ip dns” which are the upstream DNS servers.
Therefore it is not possible to use the internal RouterOS DNS server as IPv6 DNS server.

Please make the DNS server configurable in the same way, as it’s already done on the IPv4 DHCP server.

Yes, please add this!

Yup, this a must have especially or at least in the SLAAC implementation of things.

It’s just first step (I hope), but with 6.42rc you can now do:

/ipv6 dhcp-server option
add code=23 name=dnstest value=\
    0x20010db8abcd0000000000000000000120010db8abcd0000000000000000000220010db8abcd00000000000000000003
/ipv6 dhcp-server
add <other options> dhcp-option=dnstest

And then on client:

[sob@CHR2] > /ip dns print 
...
              dynamic-servers: 2001:db8:abcd::1,2001:db8:abcd::2,2001:db8:abcd::3
...
