The following part of the draft: or restricing DNS/UDP packets to no more than 1280 bytes including IPv6 headers. should be or restricting DNS/UDP packets to no more than 1280 bytes including IPv6 and IPv6 extension headers. because, in RFC2460, "IPv6 header" means 40B IP header only. It should also be noted that IPv6 extension headers, some of which, such as fragmentation headers and mobility ones, MUST be inserted without application's discretion, can be (in theory) very long that there is no minimum message size guaranteed to be carried within a 1280B packet.
