Yes, host declarations with static addresses are treated differently
to dynamic leases. They do not go through the regular lease cycle,
and they do not appear in the leases file - and they do not trigger
You can force DNS updates for them with the (IIRC)
"update-static-leases true;" statement - but the DNS will be updated
EVERY time the client renews which may increase load on your servers.
