There's nothing wrong with it, and it's done all the time. Consider the case where www.company.com server is hosted at a third party. The A record will be in the company's domain, but the PTR record will be in the hosting service's reverse domain. Just make sure that there is a corresponding A record. Some software will check for this before believing the PTR record. This is mostly done in software that uses reverse lookups in security checks; for instance, if a hosts.allow file allows access from *.company.com, it can't just believe the PTR record because anyone can put "<some-addr> PTR foo.company.com." in their reverse zone. -- Barry Margolin Arlington, MA _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
