By default, if something gets registered with a forward DNS name, it also gets a reverse record.  There are still some 
applications here that make some decisions based on a reverse record, and I’m sure there are still some servers out 
there using TCP wrappers that check to make sure the forward and reverse match before allowing connections (although 
how useful that is these days is another question).
