Option in named to turn off EDNS Globally

[Harshith Mulky]

I have tried enabling with the significant bits

server 0.0.0.0/0 { edns no; };
server ::/0 { edns no; };


But, I get the following Error

Error in named configuration:
/etc/named.conf:120: '{' expected near '/'

Error in /var/log/messages

Aug  5 11:59:19 coorg named:  failed
Aug  5 11:59:19 coorg named: /etc/named.conf:120: '{' expected near '/'


Thanks
Harshith

You need specify the significant bits.  By default all the bits are significant.

server 0.0.0.0/0 { edns no; };
server ::/0 { edns no; };

But why do you need to turn off EDNS?  Its almost always not what is needed.
