+M-Lab accepts host-managed infrastructure contributions from **organizations**, not individuals. Eligible organizations include:

+- Universities, research institutions, and public-sector bodies
+- Non-profits operating network infrastructure or public internet services                                          
+- Other organizations operating publicly documented internet services

+- Have a **verifiable public presence** — a working website, registry entry, or equivalent reference that lets M-Lab
+ confirm the organization exists and that the applicant is authorized to represent it.
+- Provide a **NOC/support email address on your organization's own domain**. Personal addresses (e.g. `@gmail.com`, 
+`@outlook.com`, `@yahoo.com`) are not accepted for this role.                                                       
+- Designate a named operational point of contact responsible for the server's health and for responding to messages
