Hello Simon,
well, i am thinking about the issue, that some setups are still using
IPv4. At least, for example, i am using IPv4 and IPv6, so it is
preferred to put those private IPv4 addresses into a private view.
But the problem is:
I would like to try IPv6 mobility and after having a DDNS setup with
stateful DHCPv6 it would be great to have it update multiple zones.
Example:
On both zones are global unicast addresses for IPv6 and on the private
zone are also private IPv4 addresses.
When also doing dynamic stateful IPv6 configuration the hosts shall send
the suggested hostname to use to the DHCPv6 server. So it would need to
update both zones.
For reverse DHCP i use common zones "in view" statement from ISC BIND,
this would update both views. But as private addresses shall be kept
private, it would need to update both zones.
Another possibility would be, is it possible to have ISC BIND serve one
zone with multiple sources? Then i could do one common zone ("in view"
statement) just for IPv6 addresses and serve both views and having also
IPv4 addresses in private view.
