While many RFCs may have fallen into the public domain, I should point out that copyright holders need not actively defend their copyrights in order to keep them. That is often true for things like trademarks and trade secrets, but not for copyrights, which retain their full validity for their entire term, whether they are defended or not. Note that every message sent by anyone to this mailing list (or any mailing list, for that matter) is also protected by copyright. This remains true whether or not individual authors choose to defend their copyrights. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
