Interestingly 61.x.1.x cannot be reached from outside of BSNL's network but 218.x.x.x and 61.x.2.x are reachable.
@vignesh_venkatesan Are you suggesting there are open resolvers ? If yes, Can you share the IP addresses ?

Bsnl has started using new resolvers
Where 61.0.1.1 and 61.1.1.1 seems to be anycasted.
61.0.2.2 and the older 218.248.112.193(Kolkata), 218.248.112.225 (Agartala), 218.248.114.129 (Chandigarh), 218.248.114.193 (Noida),218.248.112.1 (Bangalore), 218.248.112.65 (Chennai), 218.248.112.97 (Ernakulam), 218.248.114.65 (Mumbai), 218.248.114.1 (Pune) can be reached outside of BSNL.

For clarity, your previous response made me think if there were resolvers in AS9829 doing recursion for everyone on the Internet!

From a reachability perspective, I am assuming you are implying icmp(?), from AS24186, except for 218.248.112.225, 218.248.114.65 and 61.1.1.1, all (61.x/218.x) IP addresses are reachable.

@swapneelp 218.x.x.x was an open resolver until recently where it could be reached and resolve queries even outside BSNL's network but things seems to have changed.
