A big one is the .nu domain, which is extremely popular in Sweden (since “nu” means “now” in Swedish).

It’s currently controlled by the same large non-profit that controls .se (Internet Foundation in Sweden, IIS), but Niue has been wanting control of it for decades. It’s a complicated issue since .nu addresses have become incredibly important to Swedish Internet infrastructure.

Litigation was launched in 2020 but I’m not aware of any news since then.
