How to Find IP Addresses on a Network and Monitoring their Usage

Experts predict that by 2025 we’ll have more than 75 billion connected devices, a number almost triple that recorded in 2019. With networks becoming far more dynamic and complex than ever before, the ability to find IP addresses on the network is essential. As well, people are connecting to company networks with an ever-increasing number of devices, leading to increased risk not only in security but also in maintenance and management.

How to Find and Fix IP Address Conflicts

IP address conflicts are an example of textbook “network problems”. There are multiple causes for IP conflicts, and, to make things even more fun, the behavior of devices experiencing an IP conflict can vary. Let’s explore IP conflicts in depth to help better understand what they are, why they occur, and how to fix IP address conflicts. An IP address conflict is a common network issue that occurs when two or more devices on the same network have the same IP.

Network Firewall Security: Monitoring Firewalls 101

Installing a firewall onto your network is “good network firewall security”, right? Let’s be clear, it’s not – it’s the start to good security. While installing a firewall is an important component of security in a network firewall security posture, there’s much more to the process than just dropping in a piece of hardware, or enabling some new software.

What is an ARP Table?

ARP (Address Resolution Protocol) is the protocol that bridges Layer 2 and Layer 3 of the OSI model, which in the typical TCP/IP stack is effectively gluing together the Ethernet and Internet Protocol layers. This critical function allows for the discovery of a devices’ MAC (media access control) address based on its known IP address. By extension, an ARP table is simply the method for storing the information discovered through ARP.

How to Monitor Router Traffic: 6 Router Monitoring Tips

When you’re in the networking technology field, you’re going to find that there are many different types of “monitors” (like router monitoring) that you need to stay on top of, from throughput to application performance and device health. And as you become more knowledgeable, you’re going to start to understand these diverse types of traffic and equipment. It’ll become more important to you to be able to understand concepts like where traffic is flowing.

Network Design and Best Practices

With networks at the heart of the most modern business, network design can have a major impact on business outcomes. Finding the right balance of network performance, security, redundancy, and cost require a unique mix of project management and technical skill. To help you nail your next network design project, we’ll take a deep dive on the topic, provide a basic framework you can follow, and look at some best practices to keep in mind as you go.

Network Integration: Moving from Reactive to Proactive with Mature Processes

Auvik and Cherwell recently co-hosted an information-packed webinar to answer some important network integration questions facing network managers: How do we get ahead of our workload and how do we know where to start? Let’s look at some of the key takeaways from the webinar (you can watch here) on how to move from a proactive to a reactive network operation model, how network integration solutions can help put out fires faster, and when to incorporate tools to automate processes.

The Future of IT Events: Conferences in a Post-Pandemic World

IT events and technology conferences, once mind-bogglingly big in-person learning and networking opportunities, have certainly changed a lot since 2020. What started out as optimistic postponing for safety concerns quickly transformed into a new reality of virtual-only presentations and even total event redesigns due to the coronavirus pandemic. Now a year later, the outlook seems the same: another cycle of virtual-only events. We have to ask, “Is this the new future for conferences”?

What Is a Network Diagram?

Network diagrams are not only handy to have, but provide a vital look at the network topology for your team, your company, and your peace of mind. Let’s look at what a network diagram is, and why it’s so important. A network diagram is, simply put, a schematic or map of your existing network that illustrates the nodes and their connections. Network diagrams are very useful at mapping out your elements and device interactions, as well as illustrating different network topology types.
