The master browser’s list doesn’t include mappings to IP addresses; it’s used by clients to present lists of computers on the local network in network browsers.

In fact, there are two types of master browser: the domain master browser and the local master browser . The domain master browser is most often associated with networks that use an NT domain configuration, and in such configurations, the domain controller takes on this role.
