libpcap抓包ip地址不对？请帮我看看代码
我需要做一个抓包器，代码如下，我的主机ip地址是192.168.1.110，可是结果却是sudo ./sniffall 0
157.55.56.161 192.168.1.105
192.168.1.105 157.55.56.161
157.55.56.161 192.168.1.105
192.168.1.105 157.55.56.161
157.55.56.161 192.168.1.105
这个不对吧？之前我尝试过用netinet/ip.h和netinet/ether.h下面的struct ip和struct ether来算offset，可是结果的ip更奇怪了，大家看看是哪里出了问题，谢谢！

printf("%s ",src);

printf(" %s\n", dst);
