1. Single host.
2. Wildcards *.example.com.
3. Network segment: 203.74.205.32/255.255.255.0, 203.74.205.32/24.

Privilege:

Squash:

1. "No mapping": Allows all users of NFS client, including root users, to maintain original access privileges.
2. "Map root to admin": Assigns access privileges to root users of NFS client equivalent to the admin user access privileges on your system.
3. "Map root to guest": Assigns access privileges to root users of NFS client equivalent to the guest access privileges on your system.
4. "Map all users to admin": Assigns access privileges to all users of NFS client equivalent to the admin user access privileges on your system.

Security:

1. AUTH_SYS: Use the NFS client's UID (user identifier) and GID (group identifier) to check access permissions.
2. Kerberos authentication
3. Kerberos integrity
4. Kerberos privacy
