	This should have the real root servers in it.

	Insufficient information.  You have failed to give the name of the
	zone you currently have configured.

	168.192.in-addr.arpa or 1.168.192.in-addr.arpa

	If you use 168.192.in-addr.arpa you can add the records for all
	three ranges.

	If you use 1.168.192.in-addr.arpa you will need to create
	2.168.192.in-addr.arpa and 3.168.192.in-addr.arpa.
	 
> How about the in-addr.arpa file for my zone (my_domain.zone above)?

	You should NOT use IN-ADDR.ARPA.  You have NOT been delegated
	IN-ADDR.ARPA.  RFC 1918 delegates 168.192.IN-ADDR.ARPA to you
	and everyone who uses the address space defined there.

	Also if you use IN-ADDR.ARPA you will block reverse lookups for
	other sites.
