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.
Sounds like some sort of decentralized federation of server resources. I don't know, seems a bit advanced. /s
Don't ISPs already do something like this to save on bandwidth on their side? Just saving local copies of commonly accessed files.
At least I remember hearing about that a decade ago, I wonder if that can still happen now that there's basically https everywhere.
But at any rate, I believe there are at least well established methods for that.
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).
There are many places on Earth where DNS servers have high latency, low bandwidth, and intermittent connectivity, yet still function fine. It’s already a solved problem.
