That's correct.  That's why DNS and DHCP typically work hand in hand,
and why IPAM (IP Address Management) solutions are all the rage at
large organizations.

When two DHCP servers both operate in the same IP space, they must
know about each other and their their database.  This functionality
is built into the ISC DHCP server to handle redundant pairs.
