three domains, each with their own subnet.

As discussed earlier, FQDN to domain matching is based on the longest
|
||||
match. The FQDN, "myhost.four.example.com.", will match the first
|
||||
domain while "admin.example.com." will match the third domain. The
|
||||
FQDN, "other.example.net." , would fail to match any domain and would
|
||||
be rejected.
