TOPIC: Network

Network 14 years 2 months ago #7589

The CCNA books from Cisco Press say is a class A network but is only for diagnostics. The Test Out course says is not included in any class of addresses. What would be the correct answer on the 640-801?

The network is indeed reserved for test purposes. Perhaps the most famous address within it is the universal loopback address, This is a standard feature of every TCP/IP implementation so you can't use it elsewhere for 'real' communications. It is usually set up so that if you ping 127.0.0.anything on your machine then will reply. Hence the whole 127 network is reserved for test

So.....for the CCNA, is it a class A network or not.

Its technically a Class A reserved address for loopback.
