I am going to change the setup so that the RFC5006 DNS server IPv6 address
and the IPv4 DNS server addresses are the same server. This server will
have forwarding statements for the internal zones to the internal DNS
server. I imagine this will iron things out. Alternatively if the IPv4
local DNS servers were also IPv6 transport enabled I could just use it,
however, this is not the case.
Indeed. This works fine in the setup I made for my company. Public
lookups go upstream through my provider's IPv6 DNS server, local lookups
go through the intranet's DNS server. Local lookups are defined as
*.company.com and all the private IPv4 subnets. The IPv6 DNS server
itself is authoritative for IPv6 until we merge the two some day.
The last scenario you describe below is indeed another case that requires
attention. I have been doing this for years as such I have had to
manually managed two separate DNS systems. One that is authoritative
globally on the Internet and one that is locally managed.
One might think there's a need to merge those...
One thing to note, while both of the above are reasonable for the average
engineer to tackle it is unlikely that a lay person would know how to
manage these situations.
One might think the situation would improve if dual-stack RGW's were to
have dual-stack DNS servers embedded in them...
