	No.  You were told to use the name of the zone as the arguement
	to dig.

	named.conf:
	zone "0.0.127.in-addr.arpa" {
		type master;
		file "127.0.0.db";
	};

	127.0.0.db:
	$TTL 86400
	@ 	SOA 	ns.example.com. hostmaster.example.com. (
			1 3600 1200 2419200 7200 )
		NS	ns.example.com.
	1	PTR	localhost.
		
	"dig axfr 0.0.127.in-addr.arpa @ns.example.com" will work as it
	refers to a zone.

	"dig axfr 1.0.0.127.in-addr.arpa @ns.example.com" will not work
	as it does not refer to a zone but a record in a zone.

	"dig -x 127.0.0.1 axfr" is shorthand for
	"dig axfr 1.0.0.127.in-addr.arpa".

	Now is it clear "dig -x 192.168.0.3 axfr" failed.
