[edit] Bind DNS Internet Caching Server

Having a simple Bind DNS Internet Caching server can be useful in many situations. Bind does not actually contain any zone data. It merely resolves internet domain names against the root DNS servers and keeps a local cached copy of addresses it has already resolved. This has several advantages such as:
  • Speeds up DNS resolution on the local machine
  • Offload some of the work onto a DNS caching server (DNS itself requires very little resources though)
  • Reduces the load on your internet link
The ideal places to install a caching DNS server are:
  • Proxy Servers
  • Email Servers & Gateways
  • Anything that resolves internet addresses for a large portion of it's traffic
