    What is 10.0.1.255 ??

    I run a sniffer on my comp sometimes just too see whats happening on my network. Sometimes a packet is sent to 10.0.1.255, it says something about the netbios, but aren't netbios's local? Can someone explain this please? I'm not a networking guru, yet.

    That looks like the broadcast address for your private range of IP's on the near-side

    Private Range IP's
    ----------------------------------------------
    Class A | 10.0.0.0 - 10.255.255.255
    Class B | 172.16.0.0 - 172.31.255.255
    Class C | 192.168.0.0 - 192.168.255.255
    ----------------------------------------------

    Or it's a hacker spoofing Are you running a 10.x.x.x locally ?

    NetBios IPs are usually for Mixed network environments (Like Win98 , ME , probably NT4) . They name resources being shared by NetBios names (which in turn resolved to NetBios IP address) not like what's happening in W2K , which can name resources by names then to IP Address . What I want to say here is W2K by default ignore NetBios addresses .

    Type ipconfig /all in the command-line to show which machine has that ip . You have to go through each pc if you have more than one and type that command . confused

    Nothing has 10.0.1.255. If you send it to 10.0.1.255, *all* machines on that subnet will get it.

    No machine, computer, print server, router, car, boat or airplane can have x.x.x.255 (all bits on) as an address. The .255 is used as a chanel to broadcast the local subnet. If you were using 192.168.1.0 - 192.168.1.255 you can use all the numbers in -between for addressing but you can?t use 192.168.1.0 OR 192.168.1.255 these are used to broadcast the netbios. So you can relax there is no machine, computer, print server, router, car, boat or airplane on your network with that address.

    I agree with papacorn on the issue of the last digit of the IP : 10.0.1.255 . It can't be 255 but possible to be 254 .

    Exactly. For instance a Class C address block specifies the first three bytes of the address with the last byte spaning from 1 to 254. Obviously this allows for 254 individual address 195.1.32.1 to 195.1.32.254.
