Ubiquiti U7 Pro XG Review: WiFi 7 With a 10 GbE Uplink

IPv4 addresses have been exhausted globally, and the Asia-Pacific region has been feeling the pinch for years. IPv6 — with its vast 128-bit address space — is the inevitable successor, yet adoption in Australian business networks remains patchy. This guide explains why IPv6 matters now, how dual-stack deployment works, address planning fundamentals, transition mechanisms like NAT64 and DNS64, and a practical roadmap for when and how to start planning.

Link Aggregation bundles multiple physical network links into a single logical connection, increasing throughput and providing failover if a cable or port fails. Whether you are connecting a server with dual NICs to a switch or linking two switches together, LACP (802.3ad) is the industry-standard protocol that makes it work. This guide covers static vs dynamic LAG, MLAG and vPC for multi-chassis aggregation, practical use cases, and common mistakes.

VLANs have long been the primary tool for segmenting networks, but they were designed for traffic management, not security. Modern threats move laterally — once inside a VLAN, an attacker can reach every device in that segment. Microsegmentation enforces granular security policies between individual workloads regardless of network location. This guide explores east-west traffic control, software-defined microsegmentation, and practical implementation strategies for Australian businesses.

The Border Gateway Protocol (BGP) is the routing protocol that holds the internet together. Every time a user in Sydney reaches a website hosted in London, BGP is responsible for selecting the path those packets take across dozens of autonomous networks. This guide introduces autonomous systems, the difference between iBGP and eBGP, path selection, peering versus transit, and why BGP matters for multi-homed Australian businesses.

When voice calls break up, video conferences freeze, or real-time applications stutter, the culprit is rarely bandwidth alone — it is how that bandwidth is shared. Quality of Service (QoS) gives network administrators the tools to guarantee that latency-sensitive traffic reaches its destination on time, even when the link is congested. This guide explains DSCP markings, queuing mechanisms, and the practical switch and router configuration concepts every Australian IT reseller should understand.

Many small businesses start with a consumer router from their ISP and never think about it again — until performance degrades, security incidents occur, or compliance requirements demand more. Understanding the difference between a consumer router, a business router, and an enterprise firewall helps you decide when it is time to upgrade and what to look for when you do.

Every organisation that runs its own applications and data must decide where to host its servers. The three main options — an on-premises server room, colocation in a data centre, and cloud hosting — each come with distinct trade-offs around cost, control, scalability, and compliance. This guide compares all three, breaks down the real costs, and helps you decide which approach fits your business.

Remote access has become a non-negotiable requirement for modern businesses. Whether staff are working from home, IT teams need to manage servers, or help desks need to troubleshoot end-user desktops, reliable and secure remote connectivity is essential. This guide compares traditional protocols like RDP and VNC with modern Zero Trust approaches, and explains the security considerations that should shape your choice.

Deploying WiFi without a site survey is like wiring a building without a floor plan — you might get lucky, but you will probably end up with dead spots, interference, and frustrated users. A proper wireless site survey measures the radio environment, identifies obstacles, and produces a data-driven AP placement plan. This guide walks through the types of surveys, the tools you need, and the most common mistakes to avoid.
