How to Test a DNS server?
I need to do a site migration to my new server. But the server DNS server is bad, so I will use a external DNS server.
Asked to the guys of the external DNS server to add my Zones to their DNS. They told me they did it and that I can go to my registrar and change the name servers.
Is there a way or a software that allow me to test the new DNS server before the migration? I want to check settings, know if they did everything right, assigned the right IPs, the right subdomains, etc., BEFORE do the transfer. I can't risk have the site offline.
Thank you!
