I may be doing this wrong, or it may be a bug....

I'm running a class 'B' 10.10.0.0/16 network with about 700 nodes.

By DHCP scopes allow for nodes to have addresses such as 10.10.201.255.

With a class 'B' network, that is a legitimate node address, not a network
broadcast address.

NTOP appears to be interpreting this as the broadcast address and is
improperly reporting nodes as the broadcast address and is "yellow
flagging" my router with the following warning:


http://ntopserver.network.net:3000/help.html#1

   1.      Wrong network mask or bridging enabled
     ntop will report this problem for those hosts that apparently have a
     wrong netmask. ntop detects this problem when a host sends a packet to
     a broadcast address where the destination MAC address is not
     FF:FF:FF:FF:FF:FF. This could indicate that: \

     such host has a wrong netmask
     it is a bridge.
