Class E IP addresses are reserved for what purpose?

• A. Experimental use
• B. Public routing on the internet
• C. Reserved for scientific purposes.
• D. Private networks

Answer: (C)

Class E addresses are reserved for experimental use in IPv4. The 240.0.0.0 to 255.255.255.254 range was set aside in the original classful addressing scheme to allow testing of new protocols and ideas without impacting routable, everyday addresses. They are not intended for public Internet routing and aren’t used for typical private networks. Routers on the Internet generally do not route these addresses, and they are not assigned to ordinary devices. Because of that, the best understanding is that Class E is kept aside for experimental purposes rather than for public or private network use.
