SOA and PTR Records

[Adrien Beaudin]

Hi Max.

the @ represents the zone name essentially. It matters not whether the
zone file is a forward zone (ex. zone.com.) or an inverse address file
(ex. 0.0.127.in-addr.arpa) Either example you provided is correct.

If you have the zone: question.com and an entry in the named.conf file
that looks like this

zone "question.com" in { 
type master; 
file "question.com.db"; 
}; 

When the name server reads this file it knows that the zone is called
question.com (The 'Origin') If you don't feel like typing the origin
each time you type a file, you can use the @ character instead or you
may choose to implement an DNS management tool that handles file
creation for you alternately.

The only caveat is if you have subzones in your file. Read up in the DNS
and BIND book about $ORIGIN if this isn't quite clear...


Cheers,
Adrien
