Even If You Know IP address Of Any Website You Can Visit Directly. Now It Is ISP's Responsibility To Give You DNS. If You Use Airtel Airtel Will Give You DNS to connect with Any Website. There are millions of websites in the world. Everyday Website Updates. So the DNS server also has to keep updated. So Sometimes Airtel, BSNL' s DNS Servers Shut Downs. So If You Will Try To Access Google.com You Will be redirected To Any Webpage which you Have never Seen Before. So People's Use Public DNS. Google has its Own DNS server. If You Don't Want To Use Your ISP's DNS You Can You Google's Public DNS. Many Peoples Set Google's DNS in To Their Router To Connect Any Site.
