When something goes wrong in your network, you often don’t find out about it until your users are affected, and you’re left scrambling to identify the issue and understand its root cause. The faster you find out about a network issue and why it’s happening, the quicker you can implement the right fix and spare your network users from unnecessary downtime.

As the demand for specialists in information technology grows, so does the need for network administrators. Future organizations will always need dedicated experts to manage their increasingly expanding computer networks and systems. In this article, we’ll provide an overview of everything you need to know about the role of a network administrator, such as: Computer information technology isn’t going out of fashion soon, and neither are the jobs needed to run computer networks.

What is network automation software? It’s something we’re going to be seeing a lot of in the near future. Networks worldwide continue to grow at astonishing rates to supply organizations with the access and bandwidth they need to operate. But in a survey by Oracle, 76% of respondents said network complexity was one of management’s biggest challenges. As network growth increases—and complexity along with it—we’ll need efficient and scalable ways to handle it.

Wireshark is one of the most popular network packet analyzers available. It has been embraced by network admins worldwide and has become one of the essential network troubleshooting tools for IT teams. Read on to learn more about Wireshark, how to use it, and some relevant cases and alternatives. We will mainly focus on how you can use this tool to maintain a robust network within your organization.

In our RESOLVE ’22 event The SOC and the NOC, moderator and 3 Tree Tech VP of Cybersecurity Kris Taylor welcomed two esteemed guests to the stage: As Kris noted at the top of the event, we brought our panelists together to talk about “the culture of the network operating center (NOC) and security operations center (SOC).” Along the way, they discussed different philosophical and practical takes on the high-level topics of networking and security.

Are multiple IT operators accessing, utilizing, or managing your network address space? If so, then you might have noticed that one of the time-consuming network management tasks you are undertaking regularly, is allocating IP addresses to the IT operators. This is an inevitable task since, as your network scales with new physical components or technology implementations, your operators require new IPs to enable network connectivity.

Ever discovered an IP issue only after an end user reported it? If yes, you are not alone! Many network admins without a proactive monitoring solution in place have to constantly deal with recurring IP issues such as IP conflicts and subnet overutilization. As simple as it sounds, IP address management can be a tricky endeavor without the right strategy and management tools. Managing hundreds of IPs across multiple subnets and supernets can be tedious.

An application programming interface (API) provides access to the features of a business application, but with the visual elements stripped away. By using APIs, devices like tablets, self-service kiosks, point-of-sale terminals, and robotic sensors can connect up to apps running on servers in a datacenter or in the cloud. Because they give access to the heart of your business applications, it should come as no surprise that there are some APIs that the general public should not have access to.
