I've gotten several requests to post my revised version of the Ethernet protocol type codes. I've also put the file ether-prot.h onto our vax for FTP by those who have access. Thanks to everyone for updating the table, and I will continue to make changes as I receive them. Codes marked with question marks in the description are those from people who have said "I think this code might be this..." I do have two questions regarding these codes. First, the assigned numbers RFC lists 1600 as Valid and 5208 as BBN Simnet, but a number of people have said that 1600 is BBN Simnet. Could someone who is sure about these particular codes let me know what the correct numbers are? Second, someone asked me if there is a region of codes reserved for local protocols. Does anyone know of any such convention? -Nancy Connor FTP Software ...!harvard!spdcc!ftp!nancy nancy@ftp.com Ethernet protocol types The Ethernet TYPE field contains a hexadecimal number which can be interpreted to yield a symbolic Ethernet protocol type name.
