I followed the guide here: http://www.linuxhelp.net/guides/bind/

1. Last updated 2003. Is it still revelant?

2. What is the two files below?

I noticed that both has slightly different setting in the file. However the guide said to change the file numbers to my ip address. I changed the 1.1.10 to my server ip. But I cant use the 2nd file because I cannot have two duplicate files. So what should I name the 2nd file: 106.187.216 ?

Note, I only have one name server running on my VPS.

3. "0.0.127.in-addr.arpa.zone" file created syntax errors for me. I couldnt resolve it unless I commented them out of named.conf

Thanks in advance
