Why is 32768-60999 the default for local/ephemeral ports?

+3

−0

The local port range on my Arch Linux installation is 32768-60999 according to

cat /proc/sys/net/ipv4/ip_local_port_range

Wikipedia states that this range is "used by many Linux kernels" and the kernel documentation says it's the default range.

I'm especially interested in the reason for excluding ports 61000 to 65535 from use as local/ephemeral ports by default.
