You could try putting get-lease-hostnames inside the pool perhaps? Do
you have proper reverse lookup DNS zones? for example, does
'nslookup 100.18.8.10.in-addr.arpa' return the expected hostname?
You may need to put the use-host-decl-names inside a group with all
the host statements, to remove any potential conflict, eg:
group {
use-host-decl-names on;
host foo {
hwaddress ethernet <foomac>;
fixed-address foo.my-domain.net;
}
host ... {
}
}
