Google Introduce Its own Public DNS

by Harsh Agrawal on December 4, 2009

in Google

Months back I have written about Use Open DNS to increase internet speed and DNS plays a major role in your internet browsing experience. You might need Open DNS or new DNS released by Google to make sure you see the name server changes instantly , Security, Less page not found errors.

Usually when you get an Internet connection, your ISP offer you its own DNS which takes time to refresh.

A Faster DNS will make sure that while performing a website lookup, it takes the smallest roundtrip and page will load faster. Another reason to use a secure and reliable DNS system, is to avoid DNS spoofing. I used to use Open DNS earlier but after Google released its own DNS system I feel it may be better.

I just pinged both the DNS system (Google DNS and Open DNS ) Here are the results

Open DNS Latency

Open DNS Latency

Pinging 8.8.8.8 with 32 bytes of data:

Open DNS

Pinging 208.67.222.222 with 32 bytes of data:

  • Reply from 208.67.222.222: bytes=32 time=320ms TTL=54
  • Reply from 208.67.222.222: bytes=32 time=342ms TTL=54

  • Reply from 208.67.222.222: bytes=32 time=251ms TTL=54

I can clearly see the latency difference here. This made my choice clear.

Now something from Official Google announcement

Most of us aren’t familiar with DNS because it’s often handled automatically by our Internet Service Provider (ISP), but it provides an essential function for the web. You could think of it as the switchboard of the Internet, converting easy-to-remember domain names — e.g.,www.google.com — into the unique Internet Protocol (IP) numbers — e.g., 74.125.45.100 — that computers use to communicate with one another.

You can get Google DNS from official Google DNS page

For now it is

  • 8.8.8.8
  • 8.8.4.4

Have you ever tried seeing the difference after changing DNS ? Share your thoughts.

No it will be.. Last night I made a name server change to one of my client and it name server replication was not showing in Google DNS but when I changed it to OPEN DNS I can see the name server change.

One more good service from google. But as they more secured, hope not to get site censored. We love to browse each and every site.

Well, you are right. Even for me, the Google DNS server has lower latency. However, when I ran performance tests (as you know) for random domain resolution queries, the performance of the two came out comparable.

This means that OpenDNS is probably much faster at resolving queries, compared to GoogleDNS. What do you think?

Google DNS – that is one very useful service by Google. Got to hand it over to the Google think tanks!
