Right indeed, but which wins?
Let's assume following
Correct setup (example from BIND ARM):
$ORIGIN example.com.
host IN A6 64 0:0:0:0:42::1 company.example1.net.
$ORIGIN example1.net.
company IN A6 0 3ffe:8050:201:1860::
Resulting address 3ffe:8050:201:1860:42::1
Buggy setup:
$ORIGIN example.com.
host IN A6 64 0:0:0:0:42::1 company.example1.net.
$ORIGIN example1.net.
company IN A6 0 3ffe:8050:201:1860:8000::
Resulting address 3ffe:8050:201:1860:8042::1 ?
or
Resulting address 3ffe:8050:201:1860:0042::1 ?
Which one is ok?
