Broadcast Packet

I have a small network where users have been complaining of slowness. I decided to run sniffer and was really confused about a machine running on ip address 10.0.3.10 sending a packet to a non-existing ip address which is 10.0.3.127. I understand that broadcast will be sent to all the hosts in the network only to existing ip addresses, but don't understand why the broadcast is going to 10.0.3.127. It doesn't effect the machine, but ofcourse its taking the bandwidth on the ethernet wire.

Does it make sense?

Re: Broadcast Packet

Abbas,

It makes sense if your netmask is 255.255.255.128. .127 would be your brodacast address for the 10.0.3.0 network. What is the broadcast?

Re: Broadcast Packet

Thanks Bo,

Broadcast address would be 255 since I am using 24bit mask.

A-

Have you verified the network mask on the server itself? It could be set incorrectly. Also, if you used a sniffer to find the packet, what kind of packet was it? how often does it transmit?
