If you ask a DNS admin, every domain on the Internet is a sub-domain of the implicit ".". In other words, for "www.cisco.com", "www" is the hostname, "cisco" is a subdomain of "com", and "com" is a sub-domain of ".". If you write zone files, you know that the "." is explicit on the backend or you end up with some strange looking results. In any case, we have another bone-headed patent making the rounds.
Anyone know if this news item is legit or an April Fools joke? (I'm overly suspicious of everything on the Internet at this time of year.)
