/// Checks if the host machine supports IPv6 connectivity.
///
/// This function attempts to determine if the local machine has IPv6 support
/// by checking if it can obtain a local IPv6 address.
///
/// Returns `true` if IPv6 is supported, `false` otherwise.
///
/// # Example
///
/// ```
/// use tari_comms::utils::network::supports_ipv6;
///
/// if supports_ipv6() {
/// println!("IPv6 is supported on this machine");
/// } else {
/// println!("IPv6 is not supported on this machine");
/// }
/// ```
