The command "bandwhich --show-dns --dns-server ${dns_server_ip}" is a command-line instruction used to run the Bandwhich tool with additional options related to DNS (Domain Name System) traffic analysis.

Here's a breakdown of the command:

• "bandwhich": This is the actual command used to invoke the Bandwhich tool. Bandwhich is a CLI utility used for monitoring network bandwidth usage by process and connection.

• "--show-dns": This is an option or flag passed to the Bandwhich command. When used, it enables Bandwhich to display DNS (Domain Name System) traffic in its output. DNS traffic refers to the network packets sent and received for domain name resolution, i.e., translating human-readable domain names (e.g., www.example.com) into IP addresses.

• "--dns-server ${dns_server_ip}": This is another flag or option provided to Bandwhich. It is followed by the DNS server IP address (${dns_server_ip}), which needs to be replaced with the actual IP address of the DNS server you want to monitor. By specifying this flag, Bandwhich directs its DNS related analysis specifically to the mentioned DNS server. This is useful when you want to monitor the DNS traffic to a particular server, e.g., if you suspect DNS issues or want visibility into DNS resource utilization.

To use this command, you would replace "${dns_server_ip}" with the actual IP address of the DNS server you want to monitor, or you could provide the IP directly without using a variable.

Overall, the command allows you to utilize the Bandwhich tool to display network bandwidth usage, with a focus on DNS traffic and analysis for a specific DNS server.
