I ran across an interesting article about a guy who performed a host -l command on a public facing DNS server, received a complete zone transfer, republished the information, and was then sued by the owner of the DNS server for essentially hacking their system... 

Sierra Corporate Design, Inc., v. David Ritz

I especially agree with the beginning of this article:

I say what I say about the use of "host -l" because of Conclusion of Law #1: "behavior in conducting a zone transfer was unauthorized within the meaning of the North Dakota Computer Crime Law." That zone transfer was accomplished by the use of "host -l" (Finding of Fact #2). Notice that the "behavior in conducting" the zone transfer is the unauthorized action, not the republication of the information.
