I've just been monitoring our network from a laptop 192.168.1.101
called "vicky" and for the past few days ntop has correctly
identified this host, showing the name rather than the ip address.
Other hosts also seem to be OK.

However, today I noticed that three different ip addresses all
showed up as "vicky". On inspection one of them was another
local laptop 192.168.1.113 which should really be "ann-pc" and
previously ntop correctly identified it. After resetting the
stats ntop again gets it right.

So why can ntop sometimes show the wrong host name?

"vicky" is monitoring via a netgear switch with port mirroring.
