DNS Propagation

[João Alberto Kuchnier]

Hi Everyone!

Recently I enabled a new IP range on my firewall. I used this bigger
range to organize my DNS records like mail, www, ns1, ns2, and others. I
did this last weekend.

I find out that some DNS servers updated themselves with my new
registers. However, CheckDNS
(http://www.checkdns.net/quickcheckdomainf.aspx) stills resolving to my
old servers. 

I changed every record, every file of all my domains, serials, firewall
rules using the new IPs but I'm still having problems. Moreover, some
mail servers are rejecting messages from my main domain.

Here are some logs:

Oct 14 11:50:48 ns1 named[2929]: error (connection refused) resolving
'otwbhqbg.net/A/IN': 200.xxx.xxx.xxx#53
Oct 14 11:50:48 ns1 named[2929]: error (connection refused) resolving
'yuogkiz.net/A/IN': 200.xxx.xxx.xxx#53
Oct 14 11:51:05 ns1 named[2929]: client 65.202.203.203#9026: query
(cache) '12.8-15.xxx.xxx.xxx.in-addr.arpa/PTR/IN' denied
Oct 14 11:51:05 ns1 named[2929]: client 65.202.203.203#1765: query
(cache) '12.8-15.xxx.xxx.xxx.in-addr.arpa/PTR/IN' denied --> this query
problem is pointing to my old reverse.

Can someone help me?
