happy is a simple TCP happy eyeballs probing tool. It uses non‐blocking connect(…) calls to concurrently establish connections to a number of possible endpoints. This tool is particularly useful to determine whether applications implementing the happy eyeball algorithm [RFC 6555] will use IPv4 or IPv6 if both are available.
