<export> <host1>(<options>) <hostN>(<options>)...
The following methods can be used to specify host names:
Important:
wildcards — Where a * or ? character is used to take into account a grouping of fully qualified
domain names that match a particular string of letters. Wildcards should not be used with IP
addresses; however, it is possible for them to work accidentally if reverse DNS lookups fail.

Be careful when using wildcards with fully qualified domain names, as they tend to be more exact
than expected. For example, the use of *.example.com as a wildcard allows sales.example.com
to access an exported file system, but not bob.sales.example.com. To match both possibilities both
*.example.com and *.*.example.com must be specified.

By default, access control lists (ACLs) are supported by NFS under Red Hat Enterprise
Linux. To disable this feature, specify the no_acl option when exporting the file system.
