wipe-cache domain0 [domain1]::
Wipe entries from the cache. This is useful if, for example, an important server has a new IP address, but the TTL has not yet expired. Multiple domain names can be passed. Note that you must terminate a domain with a .! So to wipe powerdns.org, issue 'rec_control wipe-cache powerdns.org.'. Versions beyond 3.1 don't need the trailing dot. Consider not only wiping 'www.domain.com.' but also 'domain.com.', as the cached nameservers or target of CNAME may continue to be undesired.
