6.1.11. Inverse Query Pseudosupport

BIND by default does not support inverse queries, and this has been known to cause problems for certain microcomputer operating systems and for older versions of BIND's nslookup tool. You may decide that rather than answering with ``operation not implemented,'' named should detect the most common inverse queries and answer them with bogus information. It is better to upgrade your clients to stop depending on inverse queries, but if that is not possible, you should use the

options fake-iquery

directive in your bootfile. NOTE: the responses are in fact bogus, in that they contain ISO square brackets ( and ), so your clients will not be able to do anything useful with these responses. It has been observed that no client ever did anything useful with real inverse query responses, either.
