What is DNS (Domain Name System)?
DNS is the system that translates human-readable domain names (like allitservices.com.au) into IP addresses that computers use to communicate. Without DNS, you’d have to remember numerical IP addresses.
Why DNS matters for Australian businesses
Your network infrastructure is the foundation of your entire IT environment. Poorly designed or outdated infrastructure leads to slow performance, security vulnerabilities, and costly downtime. As businesses adopt hybrid work, cloud services, and IoT devices, a modern, well-managed network is more important than ever.
For small and medium businesses in particular, dns plays a key role in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding dns will help you have more informed conversations with your IT provider and make better decisions for your business.
