在Internet上用多播，多播地址是怎么确定的？

freegoal 2004-07-16 03:10:15
我可以随便指定一个多播地址吗？
如果随便指定，那会不会可能与别人的应用使用了同一个多播地址而产生冲突啊？

INTERNET MULTICAST ADDRESSES

(last updated 16 June 2004)

Host Extensions for IP Multicasting [RFC1112] specifies the extensions
required of a host implementation of the Internet Protocol (IP) to
support multicasting. The multicast addressess are in the range
224.0.0.0 through 239.255.255.255. Current addresses are listed below.

The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive,
is reserved for the use of routing protocols and other low-level
topology discovery or maintenance protocols, such as gateway discovery
and group membership reporting. Multicast routers should not forward
any multicast datagram with destination addresses in this range,
regardless of its TTL.

看一下《TCP/IP详解》有关多播的章节。
如果路由器允许的话，Internet上也应该是可以多播的。

ASocket 是一个TCP/UDP协议的封装库，方便快速实现TCP的长连接与UDP的单播、组播、广播等相关通信。 通过 ASocket 统一管理 TCP/UDP 相关 Socket，让其适用于Android，在UI主线程调用和回调，在子线程异步处理消息的发送与接收 特别说明 组播IP地址特别说明 多播的地址是特定的，D类地址用于多播。D类IP地址就是多播IP地址，即224.0.0.0至239.255.255.255之间的IP地址，并被划分为局部连接多播地址、预留多播地址和管理权限多播地址3类： 局部多播地址：在224.0.0.0～224.0.0.255之间，这是为路由协议和其他用途保留的地址，路由器并不转发属于此范围的IP包。 预留多播地址：在224.0.1.0～238.255.255.255之间，可用于全球范围（如Internet）或网络协议。 管理权限多播地址：在239.0.0.0～239.255.255.255之间，可供组织内部使用，类似于私有IP地址，不能用于Internet，可限制多播范围。
