I'm pretty new to Wireshark and need to figure out what the difference is between one Request packet and another one that's been requested after. I also need to do the same for a couple ACK packets as well. I started a capture and then I had to open a command prompt and release my current IP address lease and then do a renew as well (Done using a Virtual Machine) and then had to stop the capture after another Request packet and ACK packet showed up at the very bottom. I've been looking into it for a few days now and can't seem to find out what the difference is between them. I would imagine the extra ACK is for a re-acknowledgment but I could be wrong. Any ideas? Thanks!
