For instance, a couple of presentations from Roland van Rijswijk: https://ripe64.ripe.net/presentations/91-20120418_-_RIPE64_-_Ljubljana_-_DNSSEC_-_UDP_issues.pdf http://toronto45.icann.org/meetings/toronto2012/presentation-dnssec-fragmentation-17oct12-en.pdf Tony. -- f.anthony.n.finch <d...@dotat.at> http://dotat.at/ Forties, Cromarty: East, veering southeast, 4 or 5, occasionally 6 at first. Rough, becoming slight or moderate. Showers, rain at first. Moderate or good, occasionally poor at first.
