I cannot seem to create a PTR or Reverse DNS record that publishes to the internet, especially to the satisfaction of Comcast. I have tried several different models to create a reverse record for 126.96.36.199 and 188.8.131.52
Our name servers are Webmin: NS1.marketus.net and NS2.marketus.net We just switched from Men and Mice DNS Management Software. Other aspects of DNS seem to be running fine on Webmin/Virtualmin, but PTR records are not successful.
cerberus.marketus.net should reverse point to 184.108.40.206 and mail.marketus.net should reverse point to 220.127.116.11
Could a kind soul do a dig or two and coach on what we haven't done correctly? We have a /29 block of IP addresses, perhaps our Reverse Zone doesn't correctly identify this. We have it starting with 18.104.22.168/29 -- maybe we should have started with .0?
