I have a subnet mask of 255.255.255.255.( Why is my subnet mask 255.255.255.255?). I refer that from the above question that it is as good as each computer is on its own network and cant interact with one another. But if I use armitage (part of metasploit) and scan for hosts on my network, it shows me all the computers connected to my local network.
How is this possible when my subnet mask of 255.255.255.255 forces the computers to be on a different network?
Also is there any way I can change this subnet mask so I can put all the computers join the same network? (I use windows but even if I go to ipv4 properties and set a default subnet mask it does not seem to get reflected in the router.)
1You are confusing the subnet mask on the WAN with the subnet mask on the LAN. The point of a router is to route between two distinct networks and each network has its own subnet mask. Your WAN link is a point to point link, not a broadcast network that bridges a subnet. It links a machine with a single IP address to another machine with a single IP address, each of which has an interface route to the other end of the link. – David Schwartz – 2012-04-28T07:33:14.317
Okay. That makes sense. – Android – 2012-04-28T09:57:16.687
Firstly, where in the router does it say this and secondly, it will have a another address in front of like 203.1.1.11 255.255.255.255 Please update you Question with this information. the 255.255.255.255 refers specificly to the subnet mask and not at IP address. This tells the router how many bits are being used for the specified subnet. – onxx – 2012-04-30T21:02:42.613
