networking - Subnet mask of 255. 255. 255. 255 - Super User 1 255 255 255 255 is a broadcast address same as 0 0 0 0 if you want two endpoints the subnet mask would be 255 255 255 254 (however this still won't do what you are asking What you are asking for is VLANs or PVLANs (virtual or private lans) This would require hardware capable of layer2 switching and VLAN support at least
networking - Static IP address of 255. 255. 255. 255 - Super User 1 255 255 255 255 represents the local broadcast address, which is only propagated within the network This broadcast data cannot cross routers by default That is, it is a restricted broadcast address For the local host, this address refers to all hosts in the network segment (same broadcast domain)
Why is my subnet mask 255. 255. 255. 255? - Super User 11 A network with a subnet mask of 255 255 255 255 puts each device inside its own subnet, forcing them to communicate with the router before communicating with any other device
What could be the cause of multicast on Ports 3289, 22222 and 10004? I've researched the ports but can't find anything explicable - 3289 seems like it is used for certain Epson devices I have just one, but I only connect it directly via USB and it would not have been connected at the time The 22222 appears to be used by some trojans, but I don't understand why a trojan would do a multicast to this port out to the local network? And the 10004 doesn't really
What are the valid public IP address ranges? - Super User There are a number of lists on the web that define all valid public IP addresses ranges but they don't seem to be very accurate The most common list Ive found is show below This list however does
Communicating with devices on a different subnet - Super User All the bits that are 0 in the subnet mask (the last 8 for 255 255 255 0 or 24 - which is the last number in the dotted-four notation) will be 0 for the network address A full IP address actually given to a machine will not have 0's in that spot - but routing table entries work with network addresses
What does 16, 24 mean with regards to ip addresses? I understand it has something to do with subnet masks, but my question is different Let's say one of 24 ip address is 124 125 126 * with subnet mask 255 255 255 0, and it can have 256-2 hosts I am assuming we are talking about public ips here What does hosts mean here? Is it 254 router can be assigned public ips here?
What does it mean to have a subnet mask 32? - Super User For 32 that is 255 255 255 255 or 11111111 11111111 11111111 1111111 that means you can only have one ip address, on your network before needing a gateway router to get outside that network with 32 it's just you A subnet mask is a number that defines a range of IP addresses available within a network CIDR = classless inter-domain routing
