This object reports the source address, or address prefix, that a given administrator account is restricted to logging in from, typically an IPv4 address, with its exact type determined by the accompanying fnAdminAddrType object. An administrator uses this, combined with fnAdminMask, to verify that an admin account's access is properly scoped to a trusted management network rather than open to anywhere. A value of 10.0.0.0 paired with a suitable mask would restrict that admin account to logins originating from the 10.0.0.0 network.
