What exactly means iOS networking interface name? what's pdp_ip ? what's ap?

Question

I use following code to print all interface and it\'s mac address

- ( void )interfaceInfo{

int                 mib[6];
size_t              len;
char                 


        

Answer 1

lo = localhost
en = ethernet
ap = Probably for access point (if you are acting as a wifi host)

pdp_ip = maybe PDS data packet? PDS is the Phone Data Service, the data portion of GSM. Since there are four, I might postulate that PDS has the capability to offer four discrete channels.
