Not an answer, actually.
- *Avoid multiple matches*. As explained in the 'scenario description',
that's not possible in this case, but moreover, there might be other
scenarios where it wouldn't be possible either.
- *My point of view: Each computer has a (dnsmasq) DNS entry, the entry
gets in DNS by DHCP of dnsmasq*. What a computer is? the physical instance
or the virtual one? the hardware or the software? This is the key to my
scenario. And I totally agree with you: each computer should have one
entry, the problem is the definition of 'each computer'.
So, regardless of your opinion about the scenario being logical, making
sense of being valid/invalid, the question stands: is there any way to
define precedences for potentially multiple matches?
