Seems like the moon would be close enough for our standard IPv6 TTLs to work, but it seems more likely that we will have to abandon domain names in favor of something like IPFS, since it's a resource locator instead of a location locator. If you were on Mars, for example, you would not want to have to contact Earth every single time you wanted to load a web page. And so you would contact Earth the first time to load it. And then it would be saved locally. And so anybody who requested that page in the future would talk to you instead of Earth.
Nothing would stop you from running a DNS server on Mars and handling requests locally.
The problem isn't the DNS requests. It's the data synchronization that would have to occur if you were accessing a service hosted on Earth.
It's called caching and it's been mostly solved for decades (except invalidation).
