EU.org domains can be registered for free and do not expire. I've registered one more than 10 years ago, set up DNS using he.net and never had any issues.
> do not expire
The current expiration date for all eu.org domains is 2026-08-08[2].
But "eu.org" is not a TLD.
If I were looking to register a domain for 10 years, the last thing I would do is put myself at the mercy of a middleman peddling subdomains.
EU.org cannot be recommended for longevity.
