'.lb' is the
Internet country code top-level domain (
ccTLD) for
Lebanon.
The official registration rules say that it is necessary to have a Lebanese
trademark certificate for the exact name being registered (omitting the TLD and second-level label the name is being registered within). However, the example certificate shown on the registry site is indicated to be a "
trade name certificate", indicating that the registry is perhaps unclear of the distinction between trade names and trademarks.
Registrants in each of the subdomains ('.com.lb', '.edu.lb', etc.) are expected to show qualifications indicating that they are the appropriate type of entity to register in that subdomain. Additionally, registered names are required to be unique within the entire '.lb' domain (for instance, 'example.com.lb' and 'example.org.lb' cannot both be registered) because the registry wishes to keep the possibility open to drop the requirement of third-level registration and move all names to the second level.
