	You have to do that or have a "localhost" zone.
	Note localhost has two addresses 127.0.0.1 and ::1.
	
	Having localhost in the zones listed in the searchlist reduces
	the number of queries required to resolve it.

	example.db:
	localhost	IN	A	127.0.0.1
	localhost	IN	AAAA	::1

	localhost.db:
	$TTL 3600
	@	IN	SOA	...
	@	IN	NS	...
	@	IN	A	127.0.0.1
	@	IN	AAAA	::1
