Google Launches Public DNS Service

Google has just launched its very own public Domain Name System resolver, with which the company hopes to speed up internet traffic. The search giant claims its DNS is more secure (through protection against cache poisoning attacks) and faster than others.
I'm sure most of you are aware of what the Domain Name System does. When you type in a web address, you expect to be taken to said web address. DNS takes care of that for you by converting the address you typed in into its numerical variant, the IP address, making sure you actually get to the page you typed in.

Google claims that its DNS service is faster than others. "In addition to load-balancing user traffic to ensure shared caching, Google Public DNS implements 'smart' caching to increase the speed of responses," the company states, "Google Public DNS independently resolves domain names and keeps the resolutions in the cache until their time-to-live expires, at which point they are automatically refreshed. The cycle of caching and refreshing is performed offline, asynchronously with user requests, so that responses are almost always available directly from cache."
