  • They are still in use as multicast. Typically it’s for local traffic.

    I don’t think multicast over the internet would have taken off as multicast requires all routers between the source and any destinations to be multicast aware. Each would need to keep track of the subscriptions, meaning more resources that would mean higher cost. There was also less interest as one of the pluses of internet delivery was that delivery was on demand.

    In the end cdns were going to be created anyway for static content and streaming could just use the same systems to produce effectively the same improvements.

    But your next question would be why have they not done it for the experimental range.

    Well, everything knows those packets are not on the internet so will block them. If you want to ask the internet to upgrade everything for that, well just ask how the ip6 upgrade is going.




  • In case you are interested, facebook now opens links in a site of thier’s, but it contains an embedded window of the site you were linked to. This means that facebook can follow any other links you follow while on that site. It has the site effect of you not visiting that site but instead facebook’s “hidden window” shows in the history.

    It has no practical reason to exist other than allowing them to gather more data.

    Some mobile browsers might have an add-in to auto-break you out of the window.
