The record is in your config.  I operate a server with no dynamic scopes, but thousands of static mappings, and when the daemon is started, this is what gets printed:

Wrote 0 deleted host decls to leases file.
Wrote 0 new dynamic host decls to leases file.
Wrote 0 leases to leases file.

I know that static assignment is not stored in /var/db/dhcpd/dhcp.leases. So
from where can I found record of fixed address?? It is not in reserved list.

/var/db/dhcpd/dhcp.leases either.
