'rndc flushname' will clear a single name (all records, all types) out of the normal recursion cache. However, as noted by Mark last December, if an authoritative server for the domain is returning bad answers, the bad answer might come back on the next query for that rrset or that name.

If you want to clear an entire domain out of cache (example.com and all of its child names), use 'rndc flushtree' instead.
