[apologies for duplicates] Dear colleagues, Following up on a question raised during RIPE 65, we used RIPE Atlas to see if we can detect significant filtering of AAAA DNS queries or replies. Please read our findings on RIPE Labs: RIPE Atlas - A Case Study of AAAA Filtering https://labs.ripe.net/Members/emileaben/ripe-atlas-case-study-of-aaaa-filter... Kind Regards, Mirjam Kuehne RIPE NCC
