What was the primary driver for To address the issue of IPv4 address
development of IPv6? exhaustion.
When comparing IPv4 to IPv6, IPv4 uses a 32-bit address scheme, while
which IPv6 uses
of the following statements is true a 128-bit address scheme.
In IPv6-enabled networks, static FALSE
addressing is no longer allowed.
Without IPv4's network address TRUE

simpler
packet construction and better
support for peer-to-peer and
mobile-to-mobile types of
