Re: IPv6 query

There are so many great new features that arise when two devices on a link can auto-generate addresses for local communication with no engineer interaction. A great example in IPv6 is IPv6 Stateless Address Autoconfiguration. Thanks to the link-local address, it is simple for a router to assign global address information to hosts without the utilization of DHCP for IPv6. This is perfect for smaller environments that do not care about exact address assignments for hosts. They just want hosts to possess unique addresses that facilitate internetwork communication.

This is just one example of a feature accommodated by these powerful new addresses for IPv6.
