When Downtime Is Not an Option

DNS has been called the most important part of the internet that people don't know about and it's time IT managers woke up to what a professional DNS service can deliver to business.

Business is becoming more complex as we move to a digital/mobile-first economy -- fueled by the Internet of Things (IoT), big data and analytics (BDA), social media, cloud and security -- but in some respects, it is also becoming simpler. If your website and other online assets become unavailable, so does your business. That’s why many organizations have turned to an externally sourced, managed Domain Name System (DNS) service, and increasingly are adding a secondary DNS strategy to ensure redundancy. 

Essentially the phone book for Internet protocol (IP) addresses, DNS is your business gateway to customers, suppliers, partners and prospects. “DNS has been called the most important part of the internet that people don't know about and it's time IT managers woke up to what a professional DNS service can deliver to business,” says Rodney Joffe, SVP and fellow at Neustar, a Managed DNS service provider of network security solutions with over 19 years of experience in the DNS security space.  “Provisioned correctly, by a reputable specialist DNS service provider, it can defend the frontline in the fight against cyber-attacks, maximize the use of back end resources, ensure governance and be a rich source of marketing data.”

The importance of DNS, and its associated benefits, are driving the popularity of implementing managed DNS service, as well as a secondary DNS strategy. According to Neustar, UltraDNS benefits include: a 100% uptime guarantee; built-in security features such as DDoS protection, DNSSEC management, and Nameserver segmentation; advanced traffic management services to fully optimize your DNS’ performance; changes managed quickly and efficiently via a web-based portal; and detailed reports to fully understand the performance of your DNS ecosystem.

Managed DNS offerings, such as Neustar’s Authoritative DNS platform, route queries in the most efficient manner and guarantees that customer can get to their favorite online website or services in a timely fashion, and provides built in DDoS protection to prevent attackers from taking the service down. Customers get a range of options, including what is traditionally called a Primary / Secondary DNS configuration that allows the customer to implement a redundant DNS strategy. Any updates made to the primary DNS service will be sent to the secondary, via a zone transfer. 

Another option is very similar to the Primary/Secondary setup, where the customer’s existing DNS implementation is there for control purposes only, while the managed DNS provider’s network deals with queries. Called the ‘Hidden Master’ setup, it provides the best of both worlds: customers retain local DNS control while they get the benefit of an external DNS provider’s network for query resolution.

A do-it-yourself DNS strategy, or even using a single managed DNS service increases the threats to your business. They also impact your ability to realize the benefits in redundancy and reliability, performance, security and cost savings provided by a dual-source DNS strategy.
