The lack of pragmatism tells here, because it means intermediate systems have no choice but to drop.

First biggest mistake was ignoring TUBA. -G On Tue, Sep 17, 2019 at 7:46 AM Dave Horsfall wrote: > > On Mon, 16 Sep 2019, Leah Neukirchen wrote: > > > IPv6 has no checksum at all (for the header), and TCPv6 uses the same > > checksum algorithm. > > Every time I've tried to read the IPv6 spec my eyes glazed over; it was > plainly designed by a committee i.e. everybody wanted their mark on it. > > -- Dave
