dbndns binary package in Ubuntu Trusty i386

 dbndns is a fork of the djbdns package, including patches requested by
 Debian developers and Debian users, e.g. a patch to provide IPv6
 functionality.
 .
 The djbdns package provides software for all the fundamental DNS
 operations:
 .
 DNS cache: finding addresses of Internet hosts. When a browser wants to
 contact www.hotwired.com, it first asks a DNS cache, such as djbdns's
 dnscache, to find the IP address of www.hotwired.com. Internet service
 providers run dnscache to find IP addresses requested by their customers.
 If you're running a home computer or a workstation, you can run your own
 dnscache to speed up your web browsing.
 .
 DNS server: publishing addresses of Internet hosts. The IP address of
 www.hotwired.com is published by HotWired's DNS servers. djbdns includes
 a general-purpose DNS server, tinydns; network administrators run tinydns
 to publish the IP addresses of their computers. djbdns also includes
 special-purpose servers for publishing DNS walls and RBLs.
 .
 DNS client: talking to a DNS cache. djbdns includes a DNS client C
 library and several command-line DNS client utilities. Programmers use
 these tools to send requests to DNS caches.
 .
 djbdns also includes several DNS debugging tools, notably dnstrace, which
 administrators use to diagnose misconfigured remote servers.
