What You Need to Know about IPv6 Link-Local Addresses
On this page you can test the ping latency of your internet connection, and compare the performance of your IPv4 and IPv6 connectivity.
It uses fe80:: (a :: means all zeros until the required number of bits is filled, in this case fe80 is 16 bits, we need 64 bits total to be combined with the 64 bits the NIC generates to get our 128 bit address, i.e. 48 zeros) for the network portion of the address making what is known as a link-local IPv6 address.
