What does DNS server mean for Wi-Fi?
A DNS server is a computer that performs the function of a directory server for the Internet. It converts human-readable names like “www.google.
com” into the numerical IP addresses used by the Internet. When a device requests information from a DNS server, the server looks up the IP address for the requested website or service.
This process is necessary for devices to find each other on the Internet. If a device doesn’t have a corresponding IP address in DNS, it can’t communicate with other devices.
DNS servers are useful for devices that need to access the Internet, like laptops and smartphones. They’re also necessary for devices that need to access specific websites or services, like a home router.
A DNS server can be a separate computer or it can be part of a network. The most common type of DNS server is a domain name server, which is responsible for translating human-readable domain names like “google.
com” into IP addresses.
DNS servers are important for a variety of reasons, including:
-Server redundancy
-Improving website load times
-Reducing network traffic
The role of a DNS server isn’t limited to the Internet. They’re also used on corporate networks and in home networks.
-Server redundancy
-Improving website load times
-Reducing network traffic
-Providing specific website and service access
-Reducing the risk of cyber attacks.
