OK

Triggered by  "the dhcp-host entry", a snippet from manual page of dnsmasq:
   
dhcp-host=[<hwaddr>][,id:<client_id>|*][,set:<tag>][tag:<tag>][,<ipaddr>][,<hostname>]

In other words: "the dhcp-host entry" has many many meanings.

What avoiding the multiple matches?



And what is the actual problem? As in:  Why the question?

My point of view:
  Each computer has a (dnsmasq) DNS entry,
  the entry gets in DNS by DHCP of dnsmasq.
