How to use the command avahi-resolve (with examples)

The avahi-resolve command is used to translate between host names and IP addresses. It is a useful tool for resolving network names and addresses in a local network. The command can be used to resolve a local service to its IPv4 or to resolve an IP address to a hostname.

Use case 1: Resolve a local service to its IPv4

Code:

avahi-resolve -4 --name service.local

Motivation: The motivation for using this example is to resolve the IP address of a local service. This can be helpful in identifying the IP address of a service that is running on a local network.

Explanation:

• avahi-resolve: This is the command itself.
• -4: This option tells avahi-resolve to resolve the service to its IPv4 address.
• –name: This option is followed by the name of the service that you want to resolve.

Example output:

service.local	192.168.1.100

This output shows that the IP address of the service “service.local” is 192.168.1.100.

Use case 2: Resolve an IP to a hostname, verbosely

Code:

avahi-resolve --verbose --address IP

Motivation: The motivation for using this example is to resolve the hostname of an IP address. This can be useful in determining the name of a device on a local network based on its IP address.

Explanation:

• avahi-resolve: This is the command itself.
• –verbose: This option makes the command display detailed information about the resolution process.
• –address: This option is followed by the IP address that you want to resolve.

Example output:

IP	hostname.local

This output indicates that the hostname of the IP address is “hostname.local”.

Conclusion:

The avahi-resolve command is a useful tool for resolving host names and IP addresses in a local network. Whether you need to find the IP address of a local service or determine the hostname of an IP address, avahi-resolve can provide the necessary information. By using the examples provided, you can easily utilize the command to meet your network resolution needs.
