The hierarchy starts from the 'root' domain, whose name is simply '.'. Below this come top-level domains, such as 'com', 'net', 'org', 'uk' or 'jp'. Below the top-level domains are second-level domains, such as 'org.uk' or 'co.jp'. The domains in the DNS hierarchy are globally distributed, hosted by DNS name servers around the world. • A domain name registrar is an organization that allows you to purchase a domain name, such as contoso.com. Purchasing a domain name gives you the right to control the DNS hierarchy under that name, for example allowing you to direct the name www.contoso.com to your company web site. The registrar may host the domain in its own name servers on your behalf, or allow you to specify alternative name servers. • Azure DNS provides a globally distributed and high-availability name server infrastructure that you can use to host your domain. By hosting your domains in Azure DNS, you can manage your DNS records with the same credentials, APIs, tools, billing, and support as your other Azure services. • Azure DNS currently doesn't support purchasing of domain names. If you want to purchase a domain name, you need to use a third-party domain name registrar. The registrar typically charges a small annual fee. The domains can then be hosted in Azure DNS for management of DNS records. See Delegate a Domain to Azure DNS for details. • • A DNS zone is used to host the DNS records for a particular domain. To start hosting your domain in Azure DNS, you need to create a DNS zone for that domain name. Each DNS record for your domain is then created inside this DNS zone. • For example, the domain 'contoso.com' may contain several DNS records, such as 'mail.contoso.com' (for a mail server) and 'www.contoso.com' (for a web site). • When creating a DNS zone in Azure DNS: • The name of the zone must be unique within the resource group, and the zone must not exist already. Otherwise, the operation fails. • The same zone name can be reused in a different resource group or a different Azure subscription. • Where multiple zones share the same name, each instance is assigned different name server addresses. Only one set of addresses can be configured with the domain name registrar. • In Azure DNS, records are specified by using relative names. A fully qualified domain name (FQDN) includes the zone name, whereas a relative name does not. For example, the relative record name www in the zone contoso.com gives the fully qualified record name www.contoso.com. • An apex record is a DNS record at the root (or apex) of a DNS zone. For example, in the DNS zone contoso.com, an apex record also has the fully qualified name contoso.com (this is sometimes called a naked domain). By convention, the relative name '@' is used to represent apex records. • Each DNS record has a name and a type. Records are organized into various types according to the data they contain. The most common type is an 'A' record, which maps a name to an IPv4 address. Another common type is an 'MX' record, which maps a name to a mail server. • Azure DNS supports all common DNS record types: A, AAAA, CAA, CNAME, MX, NS, PTR, SOA, SRV, and TXT. Note that SPF records are represented using TXT records. • • Description reference: • https://docs.microsoft.com/ • https://azure.microsoft.com/ • • useful links: • https://docs.microsoft.com/ • Please do follow: • / mraviteja9949 • You can also learn from Microsoft labs in Github. • This video is created for educational purposes (AZ104 course). • Here is the link to practice labs: • https://github.com/MicrosoftLearning/... #ravitejamureboina
