Domain Name Service (DNS) is how a browser can translate yahoo.com to the actual IP address of the Yahoo web servers (22.214.171.124). In short, DNS translates names into IP addresses. DNS is a core network service because it has critical impacts on IT availability, performance and security. Here’s some key resources on DNS, and related topics:
“DNS and BIND tells you everything you need to work with one of the Internet’s fundamental building blocks … This book brings you up-to-date with the latest changes in this crucial service… Whether you’re an administrator involved with DNS on a daily basis or a user who wants to be more informed about the Internet and how it works, you’ll find that this book is essential reading.”
A suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by DNS for use on IP networks, DNSSEC is a set of extensions to DNS which provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality. DNSSEC is necessary because the original DNS design did not include security, but rather was designed to be a scalable distributed system. DNSSEC adds security while maintaining backwards compatibility.
From the foreword, by Cricket Lui, Chief DNS Architect and Senior Fellow at Infoblox: “Over the years, DNS — both the protocol and the servers — became the target of a variety of attacks … the DNS community developed new mechanisms to combat these attacks… …The little book you’re holding will … give you an overview of the most important DNS security technologies and advice on when you should apply them.”
