Feature request: DNSSL in /ipv6/nd

RouterOS General
1

/ipv6/nd already allows configuring dns servers and somehow also pref64 (even tough routeros does neither support plat nor dns64, so I wonder what ISP requested that specific feature).

A useful information is missing: dnssl, that is the default domain suffix. Now when I configure a network ipv6 only (including pref64) I have no way to set the dns suffix of that network (I would avoid to enable dhcp6 server at all costs, imho the only usecase for dhcp6 should be prefix delegation, now that every os can use the dns servers sent by router advertisements)

Not for this topic, but another useful feature would be announcing routes via router advertisements. This may be useful for multihomed machines so that they router specific networks on specific interfaces/routers. DHCP4 has a method for that, but afaik the only way to do this on ipv6 (without proper routing protocols) is with router advertisements "routes"

I also need this feature to set up IPv6-only and IPv6-mostly networks. I've submitted a feature request at the MikroTik Support Portal SUP-217522.

I also requested DHCP option 108 IPv6-Only Preferred support for IPv4 DHCP server.

at least dhcp4 option 108 should work according to DHCP Option 108 gets incorrect

#prefer option 4 byte value, the value is 1800 -> 1/2 hour.
/ip dhcp-server option add code=108 name=prefer-only-v6 value=0x00000708
# adapt this to your network
/ip dhcp-server network set 0 dhcp-option=prefer-only-v6
