Enterprise DNS Strategies for Complex Networks

DNS is a vital component of infrastructure that is used to communicate across global networks. For mission-critical enterprise domains, it is crucial to have the proper strategies configured to optimize traffic routing. Larger networks require a more robust DNS framework that offers a customized approach. Lets take a look at a few scenarios where DNS Made Easy can be the ideal fit for enterprise brands.

Public Authoritative DNS Solutions

DNS Made Easy specializes on the public authoritative DNS for domains in any TLD. We offer the ability to run our own software internal to an organization as well through a specialized configuration.

Local DNS Resolvers for Larger Networks

DNS Made easy works well with larger networks that set up local resolvers regionally that will respond to the same IP address over an inter-network IP Anycast announcement. This way, in case any localized resolver is no longer available another resolver (within the network) would be able to automatically answer the traffic over the IP anycast network that is just within your network.

Advanced DNS Traffic Logic for Enterprise DNS

If the localized resolver is looking to have more advanced DNS logic (to change the queries based on regionality of the request) then this would be a little more complicated as you would need to have a service that requires split-horizon DNS lookups or can recognize the EDNS client subnet accurately and change the responses accordingly.

Internal DNS Resolution

DNS Made Easy has provided the authoritative DNS for many of the largest brands on the Internet so many of those brands have asked us for help with internal DNS resolution.
Generally, in the resolving name server space we see that Unbound or other solutions are used on an open source side or there are paid services as well. But both of these solutions would usually run over a localized IP anycast announcement for better redundancy.

What is Split Horizon DNS?

Split-Horizon (aka split DNS) is when two DNS zones for the same domain are made. The two zones provide different sets of information, and are typically selected by the source address of the dns request. One zone is used by an internal network and the other by an external network provider.

DNS Checklist for Traffic Surges

• Review your domain’s redundant DNS strategy to ensure you’re covered at every point of failure.
• DNS Failover
• Secondary DNS
• Implement a DNS monitoring solution to identify suspicious traffic, spot inconsistencies, or misconfigurations
• Real-time Traffic Anomaly Detection (RTTAD)
• Advanced DNS Analytics
• Check all transactional endpoints for vulnerabilities.
• Review your domain’s SSL/TLS certificate for accuracy and expiration date
