Question 1: On page 35, line 6 of the zone file for penguin.bv; what does the value 3600 refer to?

Solution 1: That would be the TTL field as shown on page 34, and explained on top of line 37, second paragraph.

The second paragraph is incorrect and should read:

You can override the TTL for each record. In the above example the SOA records TTL has been overridden to 3,600 seconds, one hour.

The Concise Guide to DNS and BIND provides you with the technical depth and expert-level information you need to understand and administer DNS and BIND. Domain Name System (DNS) is a distributed Internet directory service. It is used mainly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, Web sites cannot be located and email delivery stalls. BIND (Berkeley Internet Name Daemon) is an implementation of the Domain Name System (DNS) protocols. This book covers setting up a DNS server and client, DNS domain zones, compiling and configuring BIND, dial-up connections, adding more domains, setting up root servers on private networks, firewall rules, Dynamic DNS (DDNS), subdomains and delegation, caching and name resolution, troubleshooting tools and techniques, debugging and logging, new features in BIND 8.2.2, and it offers introductory information on BIND 9.
