	Generally the name will be related to the address range in
	question.  0 is unrelated to 200-205.
	200.97.149.193.in-addr.arpa or 200-205.97.149.193.in-addr.arpa
	would be more appropriate choices.

	Use logatome.alex.test.francenet.fr not
	logatome.0.97.149.193.in-addr.arpa for the origin field.

	You don't need a $GENERATE directive for the NS record below.

> $GENERATE       200-205 0       NS      logatome.francenet.fr.

	Try "dig ptr -x 193.149.97.200", your original query is equivalent
	to "dig any -x 193.149.97.200" and "any" queries do not follow CNAMES.
