How to Download Files Without IPv4 on Ubuntu

This article provides a direct answer to downloading files on Ubuntu while bypassing IPv4 connections. It explains the specific command flags needed to force IPv6 usage, effectively disabling IPv4 for the transfer. Readers will learn how to use standard tools to ensure no IPv4 traffic is generated during the download process.

The primary command to download a file and disable the use of IPv4 for that session is wget with the -6 flag. This forces the utility to resolve addresses using IPv6 only. To execute this, open your terminal and type wget -6 [URL], replacing [URL] with the actual file link. This prevents the system from attempting any IPv4 connection for this specific task.

You can also achieve the same result using curl with the --ipv6 option. The command curl --ipv6 -O [URL] will download the file and save it locally without utilizing IPv4. Both methods require that your network environment supports IPv6 connectivity, otherwise the download will fail.

These commands do not permanently disable IPv4 on your Ubuntu operating system. They only restrict the specific download process to IPv6. For permanent system-wide changes, network configuration files must be edited, but for immediate file retrieval without IPv4, the wget -6 or curl --ipv6 commands are the correct solutions.
