2 software for all the fundamental DNS operations:
4 * DNS cache: finding addresses of Internet hosts. When a browser
5 wants to contact www.hotwired.com, it first asks a DNS cache,
6 such as djbdns's dnscache, to find the IP address of www.hotwired.com.
7 Internet service providers run dnscache to find IP addresses
8 requested by their customers. If you're running a home computer
9 or a workstation, you can run your own dnscache to speed up your
12 * DNS server: publishing addresses of Internet hosts. The IP address
13 of www.hotwired.com is published by HotWired's DNS servers. djbdns
14 includes a general-purpose DNS server, tinydns; network administrators
15 run tinydns to publish the IP addresses of their computers. djbdns
16 also includes special-purpose servers for publishing DNS walls
19 * DNS client: talking to a DNS cache. djbdns includes a DNS client
20 C library and several command-line DNS client utilities. Programmers
21 use these tools to send requests to DNS caches.

24 which administrators use to diagnose misconfigured remote servers.
