Hello,

I think that you must have only one IP for an A entry. You should make
CNAME.
for exemple:

www.techdreams.com.        IN    A                    204.92.67.50
ftp                                           IN    CNAME      www
mail                                        IN    CNAME        www
ns                                            IN    CNAME        www

If there is no '.' after ftp, mail, that means that is
ftp.techdreams.com...
And, in the reverse zone, you should just have on PTR for on IP.
I hope you will understand my bad english.
