DNS Real-time Directory
What would it mean for your business if your website was down for a minute? An hour? A day? Dissatisfied customers, confused prospects, and potential loss of revenue would only be the beginning.
Often, the root cause of downtime can be traced back to the Domain Name System (DNS), which is the master directory that allows Web users to find your site. If a DNS entry is incorrect or out of date, users may not be able to reach your site for up to 24 hours.
Neustar’s DNS Real-time Directory is the first service of its kind to solve the issue of delayed DNS directory updates. Put simply, the Directory collects changes made to DNS entries and then sends a message out to all directory (recursive) servers to clear the corresponding information out of its cache. Clearing the cache ensures that with the next request, new data will be pulled into the directory.
How It Works
Neustar's DNS Real-time Directory has three components: a consolidated collection of DNS changes, authoritative servers that publish those changes, and recursive servers that accept those changes. The directory leverages Neustar's powerful UltraDNS platform to improve the openness, pervasiveness , responsiveness and performance of individual websites.
In the spirit of improving Internet performance for all users and websites, Neustar is pioneering and sponsoring the DNS Real-time Initiative, which is intended to improve the Internet's performance as a whole. Contact Neustar today for more information about joining the DNS Real-time Initiative as a subscriber or publisher.
Why Your Business Needs Neustar's DNS Real-Time Directory
Today's Domain Name System (DNS) has no central management. As such, it's easy to see why proposed DNS changes can't and don't happen automatically. Whenever a DNS administrator attempts to make a change to the DNS directory for a specific website, it's generally accepted that there will be a "lag time" (known to some as a "Time to Live," or TTL) during which the site will not be accessible to Internet users. The default setting for TTL is 24 hours – an eternity in the online world.
Documented online outages have been commonplace since the inception of the Internet, and the need for a service like Neustar’s DNS Real-Time Directory has never been greater. Keeping your web content up-to-the-minute carries numerous important benefits, among them:
- Manageable disaster recovery. In the case of data centers or outages , being able to change and update IP addressing on an as-needed basis can make rebuilding faster and easier.
- Instant error correction. DNS entries can be broken in seconds, and they can be fixed just as easily. With the DNS Real-time Directory, corrections will take effect immediately - everywhere across the Internet.
- General flexibility. By speeding up the time it takes to propagate DNS changes, the DNS Real-time Directory can help streamline the way organizations manage website changes – from adding additional servers to changing IP addresses to expanding the DNS infrastructure. Fear of change and concerns about accessibility will be a thing of the past.
