How can I check Docker’s internal DNS resolution for containers?

Docker's internal DNS resolves container names, hashes, and compose service names within the same network. Unfortunately, there's no easy way to see all the resolved names at once, but you usually don't need to worry about it as long as you keep an eye on your running containers. What’s the reason you’re interested in this? Is it just for general knowledge?

You can use `docker network ls` to list all your Docker networks, and `docker network inspect [network-name]` to get details about a specific network. Each container's details can be obtained through `docker inspect [container-name]`. These commands output JSON, so you might want to get used to parsing that data with tools like jq or jsonpath. If you need a more user-friendly interface, there are various dev tools and browser extensions that display this information nicely.
