Domain Name System (DNS)
========================
Oracle Cloud Infrastructure (OCI) DNS is a cloud native DNS service that serves both internet-facing and internal requests. It can globally load balance and steer requests based on multiple characteristics.

Benefits of OCI DNS
-------------------
Looking for Dynamic DNS (DynDNS)?
---------------------------------
Dynamic DNS is the solution for ever-changing, hard-to-remember IP addresses. Create your easy-to-remember hostnames and stay connected to your IP-compatible devices.
[Learn more/Buy hostnames](https://oci.dyn.com/dynamic-dns-hostname-search/)
### 1\. Highly available internet-facing DNS
Use OCI DNS for primary or secondary internet-facing DNS.
### 2\. Secure, internal DNS for OCI workloads
Use OCI DNS for internal workloads, keeping information secure from the internet.
### 3\. Requests directed based on load, location, and source
Distribute and direct requests across multiple regions based on the destination, the health of the destination, and the location of the source.
Use cases for OCI DNS
---------------------
[View more DNS scenarios](https://docs.oracle.com/en-us/iaas/Content/DNS/Concepts/dnszonemanagement.htm)
This image shows four common use cases for OCI Domain Name System, commonly abbreviated as DNS. These use cases are:
1. Public DNS
2. Private DNS
3. Traffic load balancing
4. Traffic steering
**Public DNS**
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.
Requests from the internet can access the DNS service and the DNS service responds to requests from the internet.
**Private DNS**
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.
Requests from the on-premises environment can access the DNS service and the DNS service responds to requests from the on-premises environment.
**Traffic load balancing**
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.
**Traffic steering**
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.
Through DNS, users in different geographies can be directed through DNS to different OCI regions based on the user’s location, the nature of the DNS request, or the source network address.

### Use private DNS in interconnected VCNs and On-premises
Use your own private domain names in OCI. With the private DNS service, you also get DNS resolution between VCNs and between VCNs and on-premises networks.

### Deploy a Kubernetes cluster with automatic DNS management for multiple environments
Set up a single Kubernetes cluster deployment with OCI DNS zones and Kubernetes ExternalDNS to configure a DNS solution for multiple environments.

### OCI DNS service: More than public names
OCI offers several different ways to work with DNS to access your resources the way you want, whether you require public or private name resolution.
