  • What is the purpose of DNS?

    DNS, or Domain Name System, is a crucial system that converts domain names into IP addresses for web browsing. This process allows users to access websites by typing in a familiar domain name rather than a complex series of numbers.

  • Why are static IP addresses important for websites?

    Static IP addresses are essential for websites to maintain accessibility. With a static IP address, a website's location on the internet remains constant, ensuring that users can consistently reach the site without any disruptions or changes in address.

  • How does Dynamic DNS work?

    Dynamic DNS works by linking a custom hostname to a device with a changing IP address, such as a home network. This allows users to access devices at home, like security cameras or servers, even when their IP addresses are constantly changing.

  • What is the benefit of using Dynamic DNS?

    The primary benefit of Dynamic DNS is that it enables users to access devices at home with changing IP addresses. By associating a custom hostname with a device, users can easily connect to it remotely, regardless of the device's constantly changing IP address.

  • How does Dynamic DNS improve accessibility?

    Dynamic DNS improves accessibility by providing a consistent way to access devices with changing IP addresses. By using a custom hostname linked to the device, users can easily connect to it remotely, ensuring seamless access and control over their devices from anywhere.
