i cant under stand ??? DNS prob.

i have a problem and i need your help

when i begin with my server i dont care about DNS (just a folish boy) ....now i have a lesson about it ....
the end off lesson says :
While still in SSH do the following to verify installation has gone correctly.
Type: pico /etc/resolv.conf
It should look like this:
domain yourdomain.com
search yourdomain.com
#nameserver 127.0.0.1
nameserver ip address #1 here
nameserver ip address #2 here
Type: pico /etc/resolv.conf
It should look like this:
domain yourdomain.com
search yourdomain.com
#nameserver 127.0.0.1
nameserver ip address #1 here
nameserver ip address #2 here

search localdomain
nameserver 209.67.211.236
nameserver 209.67.211.237
nameserver 209.67.211.238
??? these are my ips
also
Check one more thing in SSH to make sure Name Server Configuration went GOOD.
Type: pico /etc/nameserverips
It should look like this:
ip address 1=ns1.yourdomain.com
ip address 2=ns2.yourdomain.com
Type: pico /etc/nameserverips
It should look like this:
ip address 1=ns1.yourdomain.com
ip address 2=ns2.yourdomain.com
209.67.211.236=ns1.DOMAIN.com
IS THAT A PROB ..???
thnx for your help
