Allowing AXFR requests to public would expose internal structure of your network and this could lead to various network attacks and spoofing. I would be happy restricting zone transfers only to my slave server IPs.
First, an open AXFR policy is not a security risk. Normally you don't put any confidential information in DNS, since all of the information in DNS is supposed to be public information...
If you want to check the quality of your delegation from the parent zone you can use the DNSCheck tool developed by .SE. It is also available as an open source tool, but for most people it is much easier to use the web interface: dnscheck.iis.se
Hello sir ,i am facing issue in dns file zone for web hosting my website which is hosted on Bluehost. The issue is it is working but when i setup google webmaster, Dns is showing red error.
The command to test for axfr (zone transfer) is incorrect.
The correct command is dig axfr @ns1.example.com example.com
