  Most common IP addresses and subnet masks share the same IPv4 formatting.

An IPv6 address is a 128-bit number that's presented in eight groups of four-digit hexadecimal numbers separated by colons. This allows for a huge range of addresses, and as a result IPv6 addressing essentially includes subnet information.

  How is 802.1X configured on OS X systems?

The network router then sends the data, via a WAN connection, on to another router that it thinks is closer to the destination. This continues across WAN connections from router to router until the data reaches its destination.
