Question { 19389 }

what is the binary value of loop back address

Answer

First of all 127.0.0.1 is the correct loopback address.
In binary that would be 01111111.00000000.00000000.00000001

(DEF)Loopback is a communication channel with only one endpoint. TCP/IP networks specify a loopback that allows client software to communicate with server software on the same computer. users can specify an IP address, usually 127.0.0.1, which will point back to the computer's TCP/IP network configuration. The range of addresses for loopback functionality is the range of 127.0.0.0 to 127.255.255.255. Similar to ping, loopback enables a user to test one's own network to ensure the IP stack is functioning properly.
