What is the common DNS address used in networking practices?

The common DNS address often used in networking practices is 8.8.8.8. This address belongs to Google's Public DNS service, which provides a reliable and fast alternative for resolving domain names to IP addresses. Google’s Public DNS is widely adopted due to its efficiency, robust infrastructure, and ease of access.

While other IP addresses listed may also serve DNS functions within local networks (like 192.168.10.10 and 192.168.1.1, which are often utilized by local routers or DNS servers), they are not typically recognized as common public DNS servers. The addresses 8.8.8.8 and 8.8.4.4 are recognized globally for their use by anyone wanting to utilize public DNS services.

Thus, these two Google DNS addresses (8.8.8.8 and 8.8.4.4) are favored choices due to their broad usage and reliability, making them stand out in common networking practice.
