I'm trying to find out the protocol numbers but I'm not sure where to look or what they even are. Can someone help me understand what protocol numbers are and where I can find them?

    IP in IP (encapsulation) is another protocol listed, with a hex value of 0x04 and a decimal equivalent of 4. This protocol allows an IP packet to be encapsulated within another IP packet.
