How To hide BIND version

"BIND (Berkeley Internet Name Domain) is the most commonly used DNS server on the Internet, especially on Unix-like systems, (...)" ( Font )

Cpanel as other webhost panels uses it to manage DNS. For security reasons, you can hide BIND version.

How to do it?

Login as root to your sever.

Edit named.conf configuration:
# nano /etc/named.conf

If you find a options function add this line to it:
version "some version";

If that function does not exist, just add it:
options {version "some version";};

Save and Exit

Restart your BIND service to take the change.
# /etc/init.d/named restart
