I am getting a lot of debugging log in my Android logcat like this:
10-16 17:21:38.422 22842-23270/package D/libc﹕ [NET] getaddrinfo+,hn 23(0x696d616765732e),sn(),family 0,flags 4

10-16 17:21:38.432 22842-23270/package D/libc﹕ [NET] getaddrinfo_proxy-, success
I am not sure where they come from because I did not have such tag in my codes, but they are clearly related to network activities.
