BIND9 forwarders

[techlists at phpcoderusa.com]

Hi,

I am configuring a web server on COX Business.

Using : Ubuntu 20.04lts and BIND9

Do I need to configuring the  Caching Nameserver
by configuring the forwards to Cox's name servers?

forwarders {
1 . 2 . 3 . 4 ;
5 . 6 . 7 . 8 ;
} ;

Thanks in advance for your help!!
