I am experiencing a very strange problem with my DNS setup and I was
hoping someone could provide some assistance. Any help would be greatly
appreciated!

With a partner, I have set up two DNS servers. Each server is acting a
primary DNS server as well as a secondary DNS server for the other
server. Here is a summary of my setup:

DNS Server #1:
Address: 209.33.199.95 (ns1.cloakedhunter.com, ns2.doctor9.net)
Master Domains: cloakedhunter.com, justpicturethisinc.com,
3hlandscapeproducts.com
Slave Domains: doctor9.net

DNS Server #2:
Address: 67.42.122.123 (ns2.cloakedhunter.com, ns1.doctor9.net)
Master Domains: doctor9.net
Slave Domains: cloakedhunter.com, justpicturethisinc.com,
3hlandscapeproducts.com

Both of my DNS servers return correct results for all of my master and
slave hostnames if asked directly. The problem, however, occurs when I
attempt to perform a lookup using a select number of other DNS servers.
When queried for one of my hostnames, rather than providing the correct
IP address, these select DNS servers will always return the IP address
of my secondary DNS server with a zero TTL. When queried immediately
after, they then return the correct IP address with the correct TTL
(3600 seconds). After that TTL expires they again return the incorrect
IP address and zero TTL. I have upgraded both of my DNS servers from
BIND 9.2.3 to 9.3.0, and it did not affect anything. Most DNS servers I
have tested work fine and always return correct results when queried.
Regardless, I must get this problem resolved as my ISP's DNS server
happens to be one of the DNS servers returning the incorrect results.
The following are the only DNS servers I have found which return the
incorrect results:

Random Charter DNS Servers:
24.213.60.77 (ns1.chartermi.net)
24.213.60.78 (ns2.chartermi.net)
24.247.24.38 (ns3.chartermi.net)
24.213.28.38 (ns4.chartermi.net)

My ISP's DNS Servers
(These servers may not accept outside queries)
204.17.177.10 (ns1.infowest.com)
204.17.177.20 (ns2.infowest.com)
