Absolutely! The first (although poorly written) is a protocol number 59.
The second represents a port number.

Take 17 or 6 as an example. As a protocol number, these represent (at least
if my memory is working this morning) TCP and UDP. As port numbers (ex #2)
they don't really represent much of anything unless some specific app is
using those ports.
