What does the C3 portion of 0xC308(BE) mean in an ICMP identifier?

Question

I am using Wireshark to analyze traffic. I know that the 8 refers to the echo (ping) type. I have been unsuccesful with finding information regarding the C3 byte.

Identifier (BE): 49928 (0xc308)

Answer 1

You can look it up in rfc792 (page 13):
Identifier
If code = 0, an identifier to aid in matching echos and replies, may be zero.
