This may be a matter that is common knowledge to this list. But please forgive me for asking. What were the reasons that the IPv6 working group decided not to include a checksum field for the IPv6 packet Header? Does it have no security impact to omit the checksum?
The short version is that in general the checksum found implementation errors, but given a working system rarely found true operational errors. It's not stupid as a debug technique, but it doesn't result in packet discard in real networks, and so was deemed unjustified.
