On point 4 there,
At this time franklin.jetbbs.com ONLY RESOLVES TO 18.104.22.168
The way I wanted it was 22.214.171.124 AND 126.96.36.199 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 188.8.131.52 to
it. This part wasn't for the reverse DNS. I got two IP addresses I'm
I got an A name for franklin, and that's the 184.108.40.206. 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 220.127.116.11. The next time they connect, it
takes them to 18.104.22.168. Is this why whenever I pinged jetbbs.com, I
only got a reply from 22.214.171.124 and not from 126.96.36.199 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!
