If you'd taken a minute to google you could have found the answer to this very frequently asked question - you can't get the client IP. Or their MAC address in case that is your next question.

You can't. It's not a "real" IP address, it's the IP address of the point of contact to the internet, which for a mobile would be up to the phone company to provide and which will probably vary as the phone moves around networks and connects and disconnects. It will also be likely to be shared...

For sending over the network the splitting of the binary data is enough. If you want smaller jpeg than you must use higher compression or split the decompressed picture in sub pictures and than compress. The article CXImage shows these techniques.

Your code will not work because the image data might contain the JPEG markers too (here: the FF D9 end of image marker). So you have to write a parser that gets also the segment length for all non stand alone markers. When such a segment is processed, pass all bytes of the length without...

You pretty much can't - and it wouldn't be a lot of use to you anyway, as nearly all LANs use 192.x.y.z addressing. You can't use it to access the client, because it will be assumed to be a local address within your server LAN.And client IP's don't go any further than the router anyway for...
