These use cases are:</p> <ol> <li>Public DNS</li> <li>Private DNS</li> <li>Traffic load balancing</li> <li>Traffic steering</li> </ol> <p><strong>Public DNS</strong><br /> In this first use cases, an OCI region contains a virtual cloud network that is serviced by the DNS service. The internet is logically and bidirectionally connected to the DNS service.</p> <p>Requests from the internet can access the DNS service and the DNS service responds to requests from the internet.</p> <p><strong>Private DNS</strong><br /> In the second use case, an OCI region contains a virtual cloud network that is serviced by the DNS service. A dynamic routing gateway is attached to the virtual cloud network. The dynamic routing gateway is logically and bidirectionally connected to an on-premises environment.</p> <p>Requests from the on-premises environment can access the DNS service and the DNS service responds to requests from the on-premises environment.</p> <p><strong>Traffic load balancing</strong><br /> In the third use case, a computer application is logically connected to two different virtual machines, which represent endpoints that the application can connect to. Traffic load balancing is a capability of the DNS service that directs applications to different endpoints based on equal or custom weights.</p> <p><strong>Traffic steering</strong><br /> In the fourth use case, two users are located in different geographies. The first user is connected to an OCI region. The second user is connected to different OCI region.</p> <p>Through DNS, users in different geographies can be directed through DNS to different OCI regions based on the user鈥檚 location, the nature of the DNS request, or the source network address.</p> </div> </figure> </div> </section>      <section class="rc118 rc118v0 cpad rw-neutral-00bg" data-trackas="rc118" data-ocomid="rc118" data-enlarge="Enlarge"> <div class="rc118w1 cwidth"> <header> <h2 class="rwaccent-3">Product tour</h2> <h3 class="rw-ptitle">Set up your global DNS</h3> </header> <div class="o-crsl col1" data-ocomid="ocrsl"> <div class="crsl-slider"> <div class="col-item"> <div class="col-framework col2 col2-thirds-col1"> <div class="col-w1"> <div class="col-item rc118w2"> <img data-src="/a/ocom/img/rc118-dns-1.png" alt="DNS management view"> </div> <div class="col-item"> <div class="col-item-w1"> <h3 class="rw-ptitle">View all your DNS features</h3> <p>View all of the features for configuring and managing your global DNS from the DNS management page in the OCI console.</p> </div> </div> </div> </div> </div> <div class="col-item"> <div class="col-framework col2 col2-thirds-col1"> <div class="col-w1"> <div class="col-item rc118w2"> <img data-src="/a/ocom/img/rc118-dns-2.png" alt="Zones section view"> </div> <div class="col-item"> <div class="col-item-w1"> <h3 class="rw-ptitle">View all your DNS zones</h3> <p>View all of the DNS zones you鈥檙e managing, including primary and secondary zone types.</p> </div> </div> </div> </div> </div> <div class="col-item"> <div class="col-framework col2 col2-thirds-col1"> <div class="col-w1"> <div class="col-item rc118w2"> <img data-src="/a/ocom/img/rc118-dns-3.png" alt="Create public zone view"> </div> <div class="col-item"> <div class="col-item-w1"> <h3 class="rw-ptitle">Create a DNS zone</h3> <p>Select from either a primary (authoritative) or secondary DNS zone type.
