How to avoid curl trying IPv6 name resolution
To make `curl` avoid IPv6 name resolution and only use IPv4, you can use the `-4` or `--ipv4` option. This forces `curl` to resolve hostnames to IPv4 addresses. Here's how you can use it: ```bash curl -4 -O http://example.com/file.txt ``` Alternatively, you can use `--ipv4` instead of `-4`: ```bash curl --ipv4 -O http://example.com/file.txt ``` This will ensure that `curl` only attempts to resolve the hostname to an IPv4 address and not IPv6.
