Great information :)<br>Thanks a lot :)<br><br><div><span class="gmail_quote">2005/11/25, Marshall Eubanks <<a href="mailto:tme@multicasttech.com">tme@multicasttech.com</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
More correctly, multicast is not provided on _much_ of the<br>public Internet. See<br><br><a href="http://www.multicasttech.com/status/">http://www.multicasttech.com/status/</a> for more details on this.<br><br>It is commonly used in Enterprise / campus networks. Whether it will
<br>meet his needs depends of course on just what those needs are.<br><br>Regards<br>Marshall<br><br>On Nov 25, 2005, at 11:08 AM, ScHinZe wrote:<br><br>> Multicast is not providing on a internet public network...<br>

<a href="mailto:tme@multicasttech.com">tme@multicasttech.com</a>>: Hello;<br>><br>> 1.) Multicast addresses are the _destination_ address, not the<br>> _source_ address for multicasts. I.e.,<br>> to send multicasts, in most systems it suffices to pick UDP and put
<br>> in a multicast address<br>> as the destination address. (My reading of the original post was that<br>> he thought that<br>> the multicast address was assigned in some fashion to the source,<br>> as a secondary
<br>> source IP address, which it isn't.)<br>><br>> 2.) Of the 224/4 multicast range that Viktor mentions below, most has<br>> been assigned by IANA for<br>> various purposes or are reserved. PLEASE do NOT pick a multicast
<br>> address at random from<br>> the 224.0.0.0-239.255.255.255 range.<br>><br>> 3.) The 239/8 range has been assigned for site and network local<br>> addresses, which need no coordination except<br>> with the local network administrator. In other words, the range
<br>> <a href="http://239.0.0.0">239.0.0.0</a> to <a href="http://239.255.255.255">239.255.255.255</a> is analogous for multicast to the 10 / 8<br>> (i.e., <a href="http://10.0.0.0">10.0.0.0</a> to <a href="http://10.255.255.255">
10.255.255.255</a>) range used for RFC1918 NAT's -<br>> just pick one.<br>><br>> 4.) If you want to have a globally routable multicast address, the<br>> best bet is to use "GLOP" space<br>> in 233/8. This is covered in the multicast faq file
