Creating or updating a dns delegation

Most registrars offer DNS hosting as a part of domain name purchase.However that doesn’t mean that you have to host your actual DNS records (your DNS Zone) with same registrar.

Whether you’re looking to take advantage of Dynamic Access Control, begin virtualizing your Active Directory infrastructure, or start using one of the other amazing features that Windows Server 2012 Active Directory offers, it all begins with getting a Windows Server 2012 added as a domain controller.Registering a domain name is one thing and hosting DNZ zone for that Domain Name is another thing. But there must be a way to know IPs of these authoritative DNS servers for a given zone.In many cases it is required to host your DNS zone with some other organization. When we register a domain name for example mydomain.com, we don’t register Therefore before finding authoritative name server for “mydomain” we need to find authoritative name server for “com” Top-Level domain.Root Name Servers are controlled by Although Root Name Servers are also uniquely named from A.to M.root-server.net, but we cannot use these names to find IP of root name servers, because for that we will again need to query some root name server for Top-Level Domain while we are already finding IP for a root name server. So a list of Root Name Servers is shipped with operating systems. Once we get hold to root name servers we can move down the DNS hierarchy asking for authoritative name servers for sub-domains using NS or Name Server Records.You need to setup NS records in parent domain’s DNS servers to point to DNS servers authoritative for your domain.
