IPv6 - Why does the Internet need a new protocol?

Ignoring questions of bandwidth, the Internet seems to be running fairly well using Internet Procotol version 4 (IPv4). Systems can connect, packets can route from one side of the world to the other over various hardware layers. So why introduce a new protocol?

IPv4 is a 20 year old design and nobody anticipated the growth of the Internet. The current and projected size has exposed some design problems with IPv4. Most problems are minor but two are major. If the major problems are not handled we can expect "the death of the Internet".
