IPv6 fixes a number of problems in IPv4, such as the limited
number of available IPv4 addresses. It also adds many
improvements to IPv4 in areas such as routing and network
autoconfiguration. IPv6 is expected to gradually replace
IPv4, with the two coexisting for a number of years during a
transition period.
