DNS (Domain Name System) is a hierarchical naming system built on a distributed database for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most importantly, it translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. With this DNS you can reach my blog just by type www.ivankristianto.com rather than using ip address like 67.228.191.153.
There are 2 big company that provide free DNS service, OpenDNS and Google Public DNS. But which one ise faster for you? I did a test to see which one is faster from my network.
For my test i’m using:
* Windows Vista SP2 with 2GB of Ram
* Internet connection speed DL 2mbps UL 512kbps

Readable result:
nslookup www.ivankristianto.com 208.67.222.222 Server: resolver1.opendns.com Start time: 17:01:04.19 End time: 17:01:04.98 Speed: 79ms nslookup www.ivankristianto.com 208.67.220.220 Server: resolver2.opendns.com Start time: 17:01:04.98 End time: 17:01:05.81 Speed: 83ms nslookup www.ivankristianto.com 8.8.8.8 Server: google-public-dns-a.google.com Start time: 17:01:05.81 End time: 17:01:06.08 Speed: 17ms nslookup www.ivankristianto.com 8.8.4.4 Server: google-public-dns-b.google.com Start time: 17:01:06.08 End time: 17:01:06.36 Speed: 28ms
From the results OpenDNS took 79ms and 83ms, and Google Public DNS took 17ms and 28ms to reach www.ivankristianto.com. So Google Public DNS si relatively faster than OpenDNS from my network. And now i’m about to change my DNS setting to use Google Public DNS.
