I work at an organization where we purchased a domain with the .DE extension (German) and we entered legal and technical issues that didn't allow us to use the domain extension (after we already bought it) without actually having an organizational presence in Germany.

I'm trying to research the rules and technicalities for a domain extension for the Netherlands.

1. What is the domain extension for the Netherlands? is it .NL?
2. Do people need to meet some legal requirements before they can actually host a site under this domain extension?
3. Any guidance on how to handle this as easily as possible?
