255.255.255.255向所有子网广播。尽管大多数路由器默认情况下都不会跨子网广播,但通常需要启用该功能。

192.168.88.255仅广播192.168.88.xxx subnet。

255.255.255.255 broadcasts to all subnets. Though most routers don't broadcast across subnets by default, you usually need to enable that capability.

192.168.88.255 broadcasts only to the 192.168.88.xxx subnet specifically.

IP地址分为网络前缀(顶部位)和主机(底部位)。假设192.168.88。可以在192.168.88.0192.168.88.254和本地广播地址 192.168.88.255 中持有255个网络地址。

但是,您需要对子网具有特定的知识来编写此广播地址。例如,192.168.88/23将拥有192.168.89.255的广播地址。

255.255.255.255只是对本地广播地址的别名,就像0.0.0.0是本地网络的别名。它们都可以在没有任何特殊配置的情况下通常使用。那是区别。您真的不会打扰使用192.168.88.255,因为您还需要一个设施来配置该值。为什么要打扰?

IP addresses are split into a network prefix (the top bits) and host (the bottom bits). Assuming 192.168.88.*** is 192.168.88.0/24 (a network mask of 255.255.255.0), the low order 8 bits can hold 255 network addresses from 192.168.88.0 to 192.168.88.254, and the local broadcast address 192.168.88.255.

But you need to have specific knowledge about the subnet to write this broadcast address. For instance, 192.168.88/23 would have a broadcast address of 192.168.89.255.

255.255.255.255 is just an alias to the local broadcast address just as 0.0.0.0 is an alias to the local network. They can both be used generically without any special configuration. That's the difference. You really wouldn't bother using 192.168.88.255 because you'd also need a facility to configure that value. Why bother?
