Hello Experts,
I have installed Bind with version: bind-9.9.5P1-2.2.2.x86_64
I have tried these Options on the server to turn off EDNS globally to all the
servers in the network we have configured
server 0.0.0.0/0 { edns no; };
server ::/0 { edns no; };
But I see the DNS Server is sending response with OPT RR
Is there a way to turn edns off?
Before anybody asks, why would I need to turn off EDNS, this is to verify the
client falling back to TCP in case EDNS is not supported on server, and the
server has to send response > 512 bytes, and the client falls back to TCP and
queries the server
Appreciate any help
Thanks in advance
Harshith
