It appears that Google has decided to add more speed to browsing in Chrome and enhance user experience with a new feature called DNS pre-resolving. The primary purpose being to increase user responsiveness to users input and to cut out latency and it was found that a lot of time was spent while the DNS was resolved for domain names. In order to overcome this Chrome has found a urn around and it resolves them prior a user navigates through the site.

With no Google in the middle and utilizing your machines own DNS resolution mechanism, the time for navigating a site first up using Chrome speeds up by 250 ms compared to other existing browsers. You can check out the time savings by typing in:
