Questions on how to setup Reverse DNS in bind 9

[Spork Schivago]

Oscar,

On point 4 there,

At this time franklin.jetbbs.com ONLY RESOLVES TO 104.238.117.105

The way I wanted it was 104.238.117.105 AND 132.148.11.44    to point to
jetbbs.com   but I think I setup the DNS record wrong.   I just added
another A record for jetbbs.com and added the IP address 132.148.11.44 to
it.   This part wasn't for the reverse DNS.   I got two IP addresses I'm
using.

I got an A name for franklin, and that's the 104.238.117.105.   Should I
have added another A name for franklin as well to setup the round robin
stuff?   You know, when someone connects to JetBBS.com, the first time they
connect, it takes them to 104.238.117.105.   The next time they connect, it
takes them to 132.148.11.44.   Is this why whenever I pinged jetbbs.com, I
only got a reply from 132.148.11.44 and not from 104.238.117.105 you think?
  Because I didn't setup another A name for franklin?   Thanks and sorry
for all the questions.   I know these probably aren't really bind related
questions anymore.   Thanks!
