Hi NANOG,
On behalf of the University of Liege (Belgium), we've been doing measurements on IPv6 Extension Headers over the last two years. More specifically, we're trying to evaluate how they are processed by routers along the path, and so from the edge. Now, we would like to compare our observations with the reality of operators. For that, we propose this very short survey [1] to operators and would really appreciate if you could complete it. Note that we guarantee anonymity of your answers by not sharing any data.
Looking forward to your input.
Thanks,
Justin
