Internet Connection Ok But No Content Use Public DNS

Many a times we run into a very unique problem wherein we see that though we are connected properly to our internet service provider (ISP), but we are able to access a few sites only while others may not load or return a “host not found at given address” error.

Typical symptoms of above problem will be”

1. The connection to the ISP is shown as connected on your PC.
2. If you are connected through ADSL modem, you see the DSL light glowing constantly as well as the internet LED blinking, showing internet activity OK.
3. You are able to see the web page of few sites, while others may not load at all.
4. Your internet access time is very slow for certain sites.
5. Till very recently you had a perfect internet connection and suddenly you are not able to access certain sites etc.

Above may be a result of improper DNS i.e. Domain Name Server settings in your network settings.
Generally we are provided with a DNS server setting which our PC fetches from the ISP at connection start up. God forbid if the ISP’s configured DNS server goes down, then you run into the above kind of problems.
