	Apparently, my eye has slipped.  There's no issue with this
	IP/netmask pair.  Rather, I see the issue with the other one:

 >>> 62.48.163.64/255.224.0.0 - 10.200.34.158

	It's the convention to have the masked-out bits of a network IP
	address to be zero.  And my guess is that route(8) may fail with
	the following if this convention isn't followed:

 >>> route: netmask doesn't match route address

	In this case:

62.48.163.64	00111110 00110000 10100011 01000000
255.224.0.0	11111111 11100000 00000000 00000000

	So, it should've probably been as follows instead:

62.32.0.0/255.224.0.0
