.B wipe-cache \f[I]DOMAIN\f[] [\f[I]DOMAIN\f[]] [...]
Wipe entries for \f[I]DOMAIN\f[] 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 \[aq]rec_control wipe-cache powerdns.org.\[aq].
Versions beyond 3.1 don\[aq]t need the trailing dot.
Consider not only wiping \[aq]www.domain.com.\[aq] but also
\[aq]domain.com.\[aq], as the cached nameservers or target of CNAME may
continue to be undesired.
