There may be hosts you need to reach that are on network 24 but on a subnet
reachable only via the gateways.

You used the host address (24.5.xx.yy) instead of the network address
(24.5.xx.0).
The route to use for a packet is determined by
>> route add -host 24.5.xx.yy eth0
>> route add -net 24.5.xx.yy -netmask 255.255.255.255 eth0

You used FF00 as the netmask; this implies a 255-host subnet.

I would try using 'route' to add a route to just add a route to the
local computers on the local interface; try
route add -host 24.5.xx.yy eth0

I am reasonably sure that it will NOT work to change the netmask; if the
netmask is wrong, then some things that need directed to the
gateway/router will not be, and stuff will break.

I have two machines plugged into a cable modem. Both have IP addresses
provided by the ISP. One is 24.6.xxx.xxx, and the other is 24.5.xxx.xxx.
Theoretically that's all fine 'cause 24. is an A class network. However the
ISP says that the netmask for these addresses should be 255.255.255.0, that
