Activities

1. Research IPv4 address classes. Build a table of valid public and private IPv4 address ranges. Then search the Internet for 'verify valid ip address'. Create and test various addresses to see if they are valid or invalid. Does the validator you are using correctly identify public, private, multicast, and experimental address ranges?
2. Search the Internet for 'what is my ip'. Identify your public IPv4 address and your public IPv6 address, if you have one. Visit ARIN.net:WhoisRWS or your local regional Internet registry and look up the address registration for your IP addresses. Then search the Internet for 'IPv6 test'. Use several websites to test your IPv6 Internet connection.
