本文详细解析了在Dubbo服务注册时，因广播地址配置不当导致的IllegalArgumentException异常，并提供了正确的地址范围及修改建议。

有些同学可能会随便填写一个地址，或者是本机地址，比如如下这样:

<dubbo:registry address="multicast://192.168.1.105:1234"/>

此时我们运行就可能会报错如下

Exception in thread "main" java.lang.IllegalArgumentException: Invalid multicast address 192.168.1.105, scope: 224.0.0.0 - 239.255.255.255

此时我们需要修改广播地址，我们修改为224.0.0.0 - 239.255.255.255其中的一个地址即可。
比如我们使用如下地址即可:

<dubbo:registry address="multicast://224.8.8.8:1234"/>
