3. dns:文件实现了域名解析的功能 4. inet_chksum.c:文件提供了 LwIP 所需的校验和功能 5. init.c:文件对 LwIP 的用户宏配置进行了检查,会将配置错误和不合理的地方,通过编译器的 #error和 #warning 功能表示出来。另外,init.c 定义了lwip_init 初始化函数,这个函数会依次对 LwIP 的各个模块进行初始化。

Thanks for reply, you are right that DNS server is handled by DHCP server in DHCP mode. I just wonder how to get it work in static situation, if it needs DNS server IP address , is there a way to tell the LWIP? will it still work? Any examples? Thanks Ping 0 Kudo...
