localhost is a hostname referring to the local computer you are currently working on, allowing it to communicate with itself through the loopback network interface.
127.0.0.1 is the numerical representation of localhost, serving the same purpose but using an IP address rather than a hostname.
host.docker.internal is a special DNS name used in Docker containers to access services running on the host machine, particularly useful for container-host interactions.
Understanding localhost, 127.0.0.1, and host.docker.internal is essential for proper networking configuration and troubleshooting in development and containerized environments.
