Workshop: DNS for Internet Service Providers
ICANN’s Office of the CTO offers the course, “DNS for ISPs”, a fast-paced, intense two-hour webinar covering myriad topics of DNS configuration and DNS security and monitoring intended for network engineers who are operating a service provider network. Topics include the benefits and challenges of operating open vs. closed DNS resolvers, best practices for operating a DNSSEC-validating resolver, discussions of encrypted DNS protocols like DNS-over-HTTPS and DNS-over-TLS, introducing the concept of running your own local copy of the root zone, reverse DNS considerations, and a discussion about the confluence of routing security (RPKI) with DNS operations.
