I've installed Wireshark on my Windows machine, and to my knowledge, the section at the bottom represents the packets in their octal and ASCII form. When I click on the IP version & the header length (20B), Wireshark highlights 45, which is 69 in decimal and E in ASCII. Could someone please explain this? Thank you.
