DNS Tricks? some DNS server filter ipv6 Microsoft NCSI

uci add dhcp domain
uci set dhcp.@domain[-1].name='dns.msftncsi.com'
uci set dhcp.@domain[-1].ip='fd3e:4f5a:5b81::1'
uci add dhcp domain
uci set dhcp.@domain[-1].name='dns.msftncsi.com'
uci set dhcp.@domain[-1].ip='131.107.255.255'

remember to uci commit

similarly ipv4only.arpa should be 192.0.0.170, 192.0.0.171, 64:ff9b::c000:aa, 64:ff9b::c000:ab
