Which command allows you to view and manage DNS settings on a Linux server?

The command that allows you to view and manage DNS settings on a Linux server is nslookup. This utility is specifically designed for querying DNS servers to retrieve information about domain names, such as their corresponding IP addresses, and to perform reverse lookups by finding the domain name associated with an IP address. It is particularly useful for troubleshooting DNS issues, as it can provide insight into the various DNS records associated with a given domain.

While dig and host are also valuable tools for DNS queries, nslookup is often preferred for its user-friendly interface and the ability to switch between different DNS servers easily.

Dig provides more detailed output and is commonly used for advanced DNS queries, making it valuable but less straightforward for some management tasks. The host command, meanwhile, is a simple DNS lookup utility that serves similar functions as nslookup but lacks the interactive features that make nslookup a more versatile choice for management.

The netstat command, on the other hand, is used for displaying network connections, routing tables, and interface statistics. It does not deal directly with DNS settings or queries, making it irrelevant in this context.
