Given the netmask (255.255.252.0), the IP/network address shown above looks
to be correct to me.

Long pause...

Well, except for windoze brain dead TCP/IP stack calculating a classful
broadcast address instead of classless. The correct broadcast address (given
the netmask) should be 24.159.203.255. Oh, and how about the 20 hop metric.
Gezzz! I'm surprised this system is even working on the network.
