What is the difference between CNAME and ALIAS records? How can you utilize these records for different use cases?

Both CNAME and ALIAS records share a common purpose: They map one or multiple domain names (such as those for different departments or regions) to a main target domain. However, their specific uses and functionality differ in various network scenarios. Network administrators need to understand these distinctions to leverage each record type effectively for robust network services. This blog will help you understand the differences between CNAME and ALIAS records and their applications.

What is DNS query resolution policy? How does it help tailor responses for specific segments in your Windows network?

Query Resolution Policy (QRP) is a security feature in ManageEngine DDI Central that allows network administrators to resolve DNS queries for specific clients’ IP addresses in the Windows Microsoft server. This helps secure the confidential network resources of an organization by preventing unauthorized individuals from accessing them. Also, QRP can help categorize certain departments to permit and restrict access to network resources.

Top 3 DNS Monitoring Tools for Reliable Uptime and Performance

DNS or the Domain Name System is critical for the function of online services like websites, and SaaS applications. The importance of DNS is highlighted by its functions. It allows computers on the Internet to find resources in a secure manner. It achieves this by using text files known as DNS records. Whenever someone hosts a website on a domain, they need to create and publish the DNS records of that domain.

What are DNS filters and how do they simplify network traffic routing?

In a world where businesses operate globally, managing DNS queries across multiple regions can be complex. When clients from various locations send queries for a domain, those queries must be routed to the most appropriate DNS host. Factors such as the client’s geolocation, IP address, and network type play a crucial role in ensuring traffic is directed to the right place for better performance. DNS filters provide the criteria for routing traffic efficiently.

When DNS Says: Talk To The Hand!

When DNS Says: Talk to the Hand! What? This started with a post on social media, which created a discussion among us industry professionals. The following conversation happened when I got to talk to my coworkers about some interesting things regarding DNS responses. Putting us gearheads in a room always results in an interesting comment or two!

The Need for Speed: Highlights from IBM and Catchpoint's Global DNS Performance Study

Despite DNS being the backbone of Internet connectivity, reliable metrics for benchmarking DNS performance are surprisingly scarce. This gap often leaves IT teams navigating in the dark, unable to effectively gauge how their DNS configurations stack up against industry standards. To address this pressing need, Catchpoint worked with IBM NS1 Connect to provide a clear, data-driven picture of DNS performance.

DNS misconfiguration can happen to anyone - the question is how fast can you detect it?

Even after decades of building web applications and troubleshooting live production issues, the thrill of solving why some random website is failing never fades. Last week, a colleague shared a link to ONUG’s website about their upcoming event in NYC this fall. I clicked on the link, and was waiting, and waiting, and waiting for the page to load and it did not. Finally, after about 30 seconds, Chrome greets me with “ERR_CONNECTION_TIMED_OUT”
