This page cannot be displayed

I am using MTNL Broadband Connection at Mumbai.
Browser : Internet Explorer 9 on one PC, and Internet Explorer 11 on other PC

From last 2 months I am facing following issue on both PCs.

Sometimes some websites don't open from IE Browser. Error displayed as "This page can't be displayed." Diagnose connection problem. Click Refresh, try after some time.

After clicking "Diagnose connection problem", sometimes problem displayed related to DNS, and sometimes no error displayed.

However, after clicking "Refresh" for 5-6 times, the same webpage loads properly.


I think this problem is related to MTNL's DNS Server.

I called MTNL helpline and lodged complaint. MTNL Service Technician visited my home, done some 2-3 settings change in Internet Explorer Browser. But these changes were irrelevant.
Problem not yet solved.

Primary DNS : 59.185.0.23
Alternate DNS : 59.185.0.50

Someone suggested me to use Google's Public DNS Address, in place of DNS Address provided by MTNL.

My question is -
Is it safe to use Google DNS Address instead of MTNL DNS Address ?
Is it allowed by MTNL ?
Anyone used this Google DNS Address in Mumbai ? Is it working better ?

Google's DNS server is a thousand times better than MTNL.
Not only you will get faster page loads, but you will also enjoy a safer browsing experience.

Google updates its server regularly, so you will be stopped from visiting a malicious webpage.
Besides it uses other techniques like DNS sinkhole to stop browsing to such webpages.

Google has the capacity to automatically scale up it's resources according to the number of web requests.
On the other hand MTNL will slow down in such cases.

So go for Google DNS.

PS: DNS (Domain Name System) is a process which converts the textual domain names (like www.google.co.in) to numerical IP address (like 173.194.121.56). The faster the process will occur, the faster will be the page load.

I second that. I have been using Google DNS for as long as I can remember and never had a problem. MTNL DNS also caches for too long and if a website changes server/IP you will have to wait a while before you can access it on the new IP but with Google DNS it is pretty quick.

Use Google DNS and you wont face such problems.

To make things easier for you to choose between what Qwerty is saying and what you been using:

Try to ping the DNS you use : 59.185.0.23

Now ping Google's DNS : 8.8.8.8

Here is my result:

Google DNS has a sub 10ms latency. What more do you want Thats the fastest response you could ever get. Try it using your own connection and I am sure you would get similar results.

Thank you "qwerty" and Thank you "admin" for your assistance.
