Hi Davey

I presented on large IPv6 packets at the May RIPE meeting

The presentation is at: http://www.potaroo.net/presentations/2016-05-23-bigipv6.pdf - key message: "Hosts should use the largest locally supported MTU for UDP (and use a 1,220 MSS for TCP)”

A write up of the presentation can be found at: http://www.potaroo.net/ispcol/2016-05/v6frags.html
