A drop request causes GBUdb to forget about an IP. If there is a record for the IP then the record is removed. The effect is that GBUdb will report the IP as unknown if queried again -- the flag will be ugly (the default) and both event counters will be zero.

<snf><xci><gbudb><drop ip='12.34.56.78'/></gbudb></xci></snf>

The <drop/> element indicates that data for this IP should be forgotten (drop the record).

The ip='12.34.56.78' indicates the IP to forget is 12.34.56.78.
