What if you change the IP of your DNS servers?
Say if at the registrar you have dns of :
dns1.domain.com point to ip.ip.ip.ip
If you shut down the DNS running on that ip (so the zonefile on the old ip will cease to exist) and then move to another provider with a new ip and setup the same dns server will the registrar automatically update to the new IP even though some registrars require you to hardcode the IP?
Thanks
