Dear DNS-WG, We would like to inform you about a Birds of a Feather (BoF) session, discussing Authoritative Name Server BCPs at RIPE 90. The session will take place Thursday, 15 May 18:00 - 19:00 (UTC+1). Last year, the DNS Resolver Recommendations document (ripe-823) was published. Its purpose is to provide clear guidance and promote effective practices in DNS resolver operations. Such a document is still missing for authoritative name servers. In this Birds of a Feather session, we will organise a panel consisting of operators responsible for authoritative name servers at the root, TLDs and 2nd and lower level domain names. We will first discuss different aspects of TLD operations, including software choice, the use of anycast, monitoring, DNS over TLS, DNS Cookies and more. At the end of the session, we would like to get feedback from the panelists and the audience on whether there is also the need for a BCP for authoritative name server operations, if RIPE would be the right place for such a document, and if a task force should be formed. Our panelists will be: • Annand Buddhev (RIPE NCC) • Doris Hauser (nic.at) • Lars Johan Liman (Netnod) • Shane Kerr (NS1 - IBM) We hope to see you all there! — Moritz on behalf of the DNS-WG chairs
