There are fundemental flaws in our IP stack.
An obvious example is ICMPv6 implosion of rfc4443: Originating a Packet Too Big Message makes an exception to one of the rules as to when to originate an ICMPv6 error message. Unlike other messages, it is sent in response to a packet received with an IPv6 multicast destination address, or with a link-layer multicast or link-layer broadcast address. But, the most serious, though subtle, flaw killing the Internet is in multihoming by routing.

Restoration of E2E transparency is an interesting research topic with elegant solutions at least for NAT and multihoming.
