在桌面应用程序中可以使用广播255.255.255.255吗

嗨，伙计们，我有一个简单的问题……我的场景是…我使用PIC18F97 J60，我的程序内存几乎满了。我没有空间在我的应用程序中启用DHCP客户端。所以，当我有静态IP时，我想配置它。我通过UDP做了一个非常简单的协议。我从桌面发送了一个请求255.255.255.255询问谁在那里。然后，我的PIC应用听和回答广播（255.255.255.255）。我的桌面应用程序可以计算出源IP，在此之后，我的桌面应用程序可以发送另一条消息到广播，要求将IP更改为同一网络IP范围。我的PIC应用程序可以在其他范围（例如，0.0.0.xxx），所以当我从桌面发送广播时，我的PIC可以听和回答广播。我的桌面应用程序会侦听并发送一个请求（使用广播）来改变IP到相同的网络范围。例如，这是很好的工作，但我的疑问是：在桌面应用程序中，我可以使用广播255.255.255.255，或者我应该使用192.1681.255吗？我担心有些路由器会掉这些包裹。建议是什么？或者我在哪里可以得到官方信息？提前感谢

    Hi guys, I have a simple question...
My scenario is... I am using PIC18F97J60 and my program memory is almost full. I don't have space to enable DHCP client in my application.
So, as I have static IP I would like to configure it. I made a very simple protocol through UDP. I sent a request from Desktop to 255.255.255.255 asking who is there. Then, my PIC application listen and answer to broadcast also (255.255.255.255). My Desktop application can figure out the source IP and after this my Desktop application can send another message to broadcast asking to change IP to the same network IP range.
For instance
My network is on 192.168.1.xxx IP range. My PIC application can be in other range (10.0.0.xxx for example) So when I send broadcast from Desktop, my PIC can listen and answer to broadcast.
My Desktop application will listen and send a request (using broadcast) to change the IP to the same network range for example.
This is working fine until now, but my doubt is : On the desktop application Can I use broadcast 255.255.255.255 or should I use 192.168.1.255 for example? I´m afraid some routers can drop these packages. What is the recommendation?
Or where can I get this official information??
Thanks in advance
