Is BSNL also blocking third party DNS servers now?

[philip]

I changed my dns settings to auto and i am always getting dns resolvers in 218.248 series. In fact if i change it to the manual dns and set 8.8.8.8 and 8.8..4.4 then also my primary and secondary addresses will be in 218 series, the dns address should be of google right i ,are they forcing me to using their own . Can anybody help me?
