Dear Sir,

   Whatis the DNS and Alternate DNS for BSNL Brodaband connection 

The primary DNS for BSNL is  218.248.245.1   and secondary DNS is  218.248.255.141   . But you do not have to care about it . Any DNS IP must work with any provider. Infact it will be much better for you to use Open DNS ip address as they are providing a better service than BSNL for DNS .

 

Open DNS   IP address:

208.67.222.222   primary 

208.67.220.220     secondary
