Thanks for the question!
Currently, we are able to register the following domain types through our domain registrar: .com, .net, .org, .us, .biz, or .info. This does not mean that you cannot use a different top-level domain type to host your website. So, the answer to your question is, "YES" you are able to use a foreign domain type like .mn for your website. Even though we can not register the domain, you can use the domain type for your primary (main) domain, add-on domains, or parked domains as long as they are registered to an official domain registrar on the internet.
I hope this helps to clarify the issue! Please let us know if you have any further comments or questions.
Thank you for your help.
