DNS Google has 70 billion requests per day

Reason to celebrate. Google announced this week that the DNS service that maintains accounts for only 70 billion requests per day Internet. The absurd number makes the company the largest provider of public DNS in the world, arriving in front of formidable competitors - notably OpenDNS, most famous for offering a free DNS provider.


The curious thing is that the strength of Google Public DNS is mainly outside the United States. The main economic market accounts for only 30% of requests. The remaining users are from different countries. According to Google, there is a strong presence in South America and Europe, as well as countries where the company recently opened local DNS servers.

I've always been fan of OpenDNS. However, I turned my coat and support the Google Public DNS since the service began. The OpenDNS has its advantages, such as filters for various contents (I wrote about it in Tecnoblog). Resources are very good that not everyone uses. I do not use. So when I set up my devices and routers to use Google Public DNS.

Google says that a proposal to deal with CDNs is under discussion. In short, the CDNs are servers that replicate around the world information on Google's computers (and other companies). Access to these servers should be faster due to the physical location, which causes the decrease latency. Google tries to topple a way for DNS providers cope better with the CDN, automatically directing traffic to the CDN server type as closely as possible.

It's only two years since Google Public DNS appeared. Good time to show that Google is interested in a faster internet as a whole. They get out of it because the faster the page itself and partners that display advertising them better. We all know.

To configure the DNS of Google is just going in the network properties of your computer and add the following addresses: 8.8.8.8. and 8.8.4.4. The addresses for those using IPv6 are: 2001:4860:4860 2001:4860:4860 :: :: 8888 and 8844.
