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

A detailed and practical guide to DNS implementation, configuration, and administration

This book examines many of the best DNS servers available. The book covers each server's benefits and disadvantages, as well as how to configure and deploy it, and integrate it into your network infrastructure. It describes scenarios where each server is particularly useful, so you can choose the most suitable server for your site. The book also explains how DNS data can be stored in LDAP directories and SQL databases. This lets you build robust DNS systems that can be automated, and can be managed by multiple, distributed, system managers. There is an extensive tutorial on using LDAP with DNS. Other important topics covered include: performance, security issues, integration with DHCP, DNSSEC, internalisation, and specialised DNS servers designed for some unusual purposes.

This booklet serves as a guide of basic principles of trunk stabilization and individual exercise positions for self-treatment according to Dynamic Neuromuscular Stabilization (DNS). The DNS concept will help you train optimal trunk stabilization and muscle coordination, which is a fundamental aspect in rehabilitation of any musculoskeletal pain and dysfunction. During rehabilitation or any athletic activities, proper trunk stabilization is the first step in prevention of overloading and protection of body during movement activities. Exercising in DNS positions allows for an ideal trunk stabilization with permanent analgesic effect. Please download this booklet and view a sequence of photographs of DNS self-treatment positions with easy to understand instructions.
