  DNS and BIND tells you everything you need to work with one of the Internet's fundamental building blocks: the distributed host information database that's responsible for translating names into addresses, routing mail to its proper destination, and even listing phone numbers with the new ENUM standard. This book brings you up-to-date with the latest changes in this crucial service. The fifth edition covers BIND 9.3.2, the most recent release of the BIND 9 series, as well as BIND 8.4.7. BIND 9.3.2 contains further improvements in security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). 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. Topics include: * What DNS does, how it works, and when you need to use it * How to find your own place in the Internet's namespace * Setting up name servers * Using MX records to route mail * Configuring hosts to use DNS name servers * Subdividing domains (parenting) * Securing your name server: restricting who can query your server, preventing unauthorized zone transfers, avoiding bogus servers, etc. * The DNS Security Extensions (DNSSEC) and Transaction Signatures (TSIG) * Mapping one name to several servers for load sharing * Dynamic updates, asynchronous notification of change to a zone, and incremental zone transfers * Troubleshooting: using nslookup and dig, reading debugging output, common problems * DNS programming using the resolver library and Perl's Net::DNS module

  This book is a complete guide to the Internet's Domain Name System (DNS) and the Berkeley Internet Name Domain (BIND) software, the UNIX implementation of DNS. In this second edition, the authors continue to describe BIND version 4.8.3, which is included in most vendor implementations today. In addition, you'll find complete coverage of BIND 4.9.4, which in all probability will be adopted as the new standard in the near future.DNS is the system that translates hostnames (like rock.ora.com ) into Internet addresses (like 192.54.67.23). Until BIND was developed, name translation was based on a host table ; if you were on the Internet, you got a table that listed all the systems connected to the Net and their addresses. As the Internet grew from hundreds to hundreds of thousands of systems, host tables became unworkable. DNS is a distributed database that solves the same problem effectively, allowing the Net to grow without constraints. Rather than having a central table that gets distributed to every system on the Net, it allows local administrators to assign their own hostnames and addresses and install these names in a local database. This database is automatically distributed to other systems as names are needed.In addition to covering the basic motivation behind DNS and how to set up the BIND software, this book covers many more advanced topics, including using DNS and BIND on Windows NT systems; how to become a parent (i.e., delegate the ability to assign names to someone else); how to use DNS to set up mail forwarding correctly; debugging and troubleshooting; and programming. Assumes a basic knowledge of system administration and network management.
