It's a well-known system administration aphorism that everything is a DNS problem. It should come as no surprise that many people came to Tuesday morning's tutorial on DNS and DNSSEC presented by Shumon Huque. Shumon began with an introduction to the basic components and architecture of DNS, including the hierarchical structure of domain names and the differences between authoritative servers, resolvers, and clients.
