    Recently installed ZoneAlarm on my machine, and I'd like to understand a bit
    more about some of the things it is doing, and this is one I'm not sure
    about. The alert says "The firewall has blocked Internet access to
    6to4.ipv6.microsoft.com ( (IP Protocol 41) from your computer."
    Is this something I should be worried about, or is it something I can
    ignore, or is it even an access I should be allowing to happen, and if so
    what is likely to be requesting the access?
