UDP Multicast question


Posted on 16th Feb 2014 07:03 pm by admin

Hey,

Im not really in the know when it comes to network related programming and activities, i know the diference between TCP/UDP and have the jist of it all...

Did you know?Explore Trending and Topic pages for more stories like this.
However one thing ive just been reading that i didnt know was that UDP supports multicasting a message to a given address within a range. Now i was just wondering is this restricted to local networks, or can this be done via the internet as well?

Using an MMO as an example, if someone in an area moved with this method you could just send out this one update to a broadcast group and everyone would get the updates, but the article only mentions its usage within local networks, so is there some restriction online to using this?
