All of the information is already there. The answer is that you shouldn't necessarily have a reverse file for every domain file. In fact, with today's proliferation of domain names, most likely such a setup would be incorrect. You should have a reverse file for every network. For instance, if you've got one class C network and 15 domain names, you should have 15 domain zone files and one reverse file. For a more complex example, suppose you've got a RAIC of 6 servers, but for greater reliability, you've spread them out across 6 offices, each with a separate class C network. Further suppose that each one is responsible for 15 websites, each with a different domain name, so that no two sites are in the same second-level domain. Now, since this is a RAIC, suppose that each webserver is responsible for the same 15 websites, so that altogether, they constitute 15 websites. You should have 15 domain zone files and 6 reverse zone files. None of the domain zones contain all the information of any of the reverse zones, and vice versa. The PTR records must be kept in a location that is determinable by the IP address, and all other records need to be kept in a location that is determinable by the domain name. Sorry if this sounds like a rant... ------------------------------- Chris Buxton Independent Consultant Specializing in Web Development
