While it's not exactly a problem, it does give away that you're running
bind9 (I do like the new 'version' option where you can set the
version.bind reply) even if you change the version to appear to be a bind8
server.
"allow-query" lets you control who can see that information:
zone "bind" chaos {
allow-query {
127.0.0.1 ;
xxx.xxx.xxx.xxx/len ;
} ;
type master;
file "filename";
};
