Dns And Bind - Cricket Liu

. .

Résumé :
DNS and BIND discusses 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 many other services. As the authors write in the preface, if you're using the Internet, you're already using DNS-even if you don't know it. The fourth edition covers BIND 9, which implements many new and important features, as well as BIND 8, on which most commercial products are currently based. DNS security is greatly improved with BIND 8 and 9. 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. ? New BIND 9 features, including views and IPv6 forward and reverse mapping ? The DNS Security Extensions (DNSSEC) and Transaction Signatures (TSIG) ? Mapping one name to several servers for load sharing ? Dynamic updates, asynchronous notification of changes 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
