Domain Name System (DNS)
The Domain Name System (DNS) is a distributed internet system that maps human-readable names (such as Oracle.com) to IP addresses and serves as the first link in the customers’ digital supply chain. Oracle’s globally distributed DNS service offers enhanced DNS performance, resiliency, and scalability so that end users connect to customers’ applications as quickly as possible from wherever they are.
Dynamic DNS (DynDNS)
Dynamic DNS is the solution for ever-changing, hard to remember IP addresses. Start a free trial or buy Dynamic DNS to create your easy to remember hostnames today.

DNS features
Optimize customers’ digital assets and ensure that users can reach them as quickly as possible.
DNS responsiveness
Customers leverage industry-leading DNS query response times (less than 30 milliseconds) to optimize their application and digital asset performance. Propagate new or modified DNS records globally in under a minute.
Supported records
Oracle supports 27 common DNS resource record types, including A, AAAA, CNAME, DNSKEY, MX, NS, PTR, SOA, and TXT.
Authoritative DNS
Customers manage DNS updates and domain names via Oracle’s standards-based Authoritative DNS service, which provides low-latency global DNS resolution for web-based properties and automatic translation of domain names into IP addresses.
Secondary DNS
Setting up a secondary DNS as a redundant complement to the customer’s primary DNS service ensures critical applications remain available and that end users can reach applications faster.
Dynamic DNS
Dynamic DNS is the solution to an ever-changing, hard to remember IP address. Create an easy-to-remember hostname and stay connected to your IP-compatible device. You get 30 hostnames per purchase.
DDoS protection
DDoS protection is an always-on detection and mitigation platform for common DDoS volumetric attacks. The service protects against common layer 3 and 4 attacks like SYN floods, UDP floods, ICMP floods, and NTP Amplification attacks. DDoS Protection is included with all Oracle Cloud Infrastructure (OCI) accounts and no configuration or monitoring is required. Monitoring is provided around the clock for malicious activity and delivered at no extra cost.
Global anycast network
Anycast addressing optimizes DNS performance, enabling consistent user experiences across the globe. Within an anycast network, DNS requests are answered by the point of presence (PoP) closest to the user making the request—ensuring the fastest possible DNS performance.
Leading telecom provider in the Nordics chooses Oracle for DNS
“We got it up and working quite easily, had a great experience with our trial account, and got a great feel early on for the product instead of just reading product documentation.”Hakon Smeplass, System Manager, Telenor
DNS use cases and benefits
-
Intelligent traffic routing
DNS traffic management allows customers to intelligently route user traffic across the internet by offering geolocation steering, load balancing, ASN, and IP-prefix steering. This provides optimized response times for web-facing applications, allowing users to reach them as quickly as possible. This service is integrated with Oracle Health check services for endpoint monitoring.
-
High availability
Oracle DNS operates out of geographically distributed, high-availability data centers on separate power grids, flood plains, and fault lines, and deploys fully redundant connections to multiple ISPs to ensure uninterrupted service. Secondary DNS creates redundancy for web-facing applications.
-
Easy-to-use APIs
Customers streamline DNS integration with web-facing applications and automate routine DNS configuration tasks using the console, OCI API, terraform and multiple SDKs.

Reference architecture for hybrid DNS high availability in OCI
The domain name system (DNS) architecture we deploy in Oracle Cloud Infrastructure (OCI) is a hybrid DNS workload that follows a hub-and-spoke topology. This setup provides operational effectiveness and makes managing the DNS in OCI easier. In this post, we focus on the high availability and resilience of the private DNS that we can achieve with the help of dynamic host configuration protocol options in a VCN.
