  We use the HotSpot feature on a Mikrotik box as a captive portal.  It doe=
s not re-direct IPv6 web traffic but it does redirect all IPv4 DNS traffic =
to a DNS resolver that only answers with A records.  Once a device has been=
 authenticated IPv4 DNS traffic goes to a DNS server that will answer with =
AAAA records also.
