Change of SOA in DNS Registrar
Hi F5 Community,
We would like to seek your experience if you already encounter this migration scenario.
Questions:
We would like to know how we can successfully transfer the DNS Zone SOA to our F5 Listener?
Description:
Currently the DNS zone ( ex. xyz.com ) SOA is a "Public ISP External DNS" defined in DNS Registrar.
Then what we did is we created manually the DNS zone records manually in our F5 GTM ( with Public IP Listener ).
Note: We don't enable zone sync/transfer from "Public ISP External DNS" to "F5 Listener IP".
A. Based on this, can we just add our F5 Listener IP as 3rd NS ( nameserver ) just to test if DNS request (prod traffic) in the DNS domain registrar will resolve?
OR
B. Do we need to totally remove the SOA NameServer and change it to the F5 Listener IP and Hostname? If we will do this is it possible that this be propogated immediately? Would there be any effect on the DNS Zone File Serial Number currently cache on other DNS Server?
Thank you in advance.
