Question: 1 / 690

What could be the reason for not being able to access the internet despite having correct IP address parameters?

The computer is not connected to the router

Your ISP's DNS server is down

The ability to access the internet depends on various components functioning properly beyond just having the correct IP address settings. In this case, if the ISP's DNS (Domain Name System) server is down, it prevents the computer from resolving domain names to IP addresses, which is essential for web browsing. While the device may have valid IP information, such as an IP address, subnet mask, and gateway, if DNS resolution fails, users will be unable to access websites by name, leading to an impression of being offline.

Having a working router connection, correctly configured static IP settings, and an unblocked firewall are vital aspects of internet access, but they don't account for failures in DNS services specifically provided by the ISP. If the DNS server isn't accessible, any HTTP or HTTPS requests made will fail, resulting in an inability to reach desired online content.
