127.255.255.255 won't ping why?

  • do u mean ping fails? or other error ? is it in cisco routers?

     

  • this is a loopback broadcast. Interesting, but the 127 falls under the class A IP addresses. Without specification of subnetmask you wouldn't be able to ping the broadcast. Also, are you sure you created a loopback interface in the first place? you should either see a U.U.U etc for destination is Unreachable, or the pings will fail. Does this help what you are looking for?

  • if you ping 127.255.255.255, you should be able to get replay back from any other host in your range that's 127.x.x.x. This range is reserved for loopback.
