It's in "Troubleshooting Campus Networks." :-)

The IP protocols are pretty straightforward. The IANA list for
application-layer protocols and their UDP/TCP port numbers isn't so great
because it doesn't say which is usually used, UDP or TCP. For example, it
says this for FTP:

ftp-data         20/tcp    File Transfer [Default Data]
ftp-data         20/udp    File Transfer [Default Data]
ftp              21/tcp    File Transfer [Control]
ftp              21/udp    File Transfer [Control]

But nobody runs FTP on UDP.

That's why a book is sometimes better than the IANA documents. The book also
gives you the "truth" about "registered port numbers."

But that's port numbers. For IP Protocol numbers, the IANA doc is fine.
