What are the legal considerations surrounding the use of '007' in a domain name like 007.site, especially concerning copyright or trademark?

The term '007' and associated James Bond imagery are likely protected by copyright and trademark. Using them commercially without permission from the rights holders (EON Productions) could result in legal action. A fan site that is non-commercial and clearly disclaims any official affiliation might be acceptable under fair use principles, but it's a legal grey area and professional legal advice should be sought to be completely safe.
