Networking and ZoneAlarm free

I'm networking two computers, one Win98SE, the other XP. I also
installed ZoneAlarm free on the Win98 machine. I have to add the
network to a trusted zone in ZoneAlarm so it won't block the printer
and file sharing. I'm not sure what range of addresses I should put in
the trusted zone. Right now, they're being assigned addresses in the
169.x.x.x range. The computers will also be accessing the internet
through the router. So, the IP addresses are being generated by DHCP.
Can someone tell me the safe range that Windows uses for local
networks? I want to make sure I'm not opening the computer for access
from the internet, just between the two computers.
Thanks.

The 169.254.x.x addresses indicate that there's no DHCP server on the
network to assign addresses. When you connect a router or other
device with a DHCP server it will probably assign addresses in
the192.168.x.x range.

Both of those ranges are non-routeable, meaning that they can't be
reached over the Internet, so it's safe to put both of them in the
Trusted zone.

Thanks. No, there is no DHCP server right now. I'm testing, so have
the two computers linked through a router. However, the Win98 machine
will be going back to someone where it will be connected through a
wireless router so both XP and Win98 will share an internet
connection.
So, it would be safe to enter those two ranges in the trusted zone of
ZoneAlarm? And those ranges would be entered: 169.245.999.999 and
192.168.999.999? Not sure what the upper range would be. However, I'm
thinking you're saying the ranges would start and end with 169.254 and
192.168 only? Is that right?

Sorry, I suppose that would be 169.254.0.0 through 169.254.255.255 and
192.168.0.0 through 192.168.255.255, right?

Right.

When you connect the router, you'll find that it probably uses one of
the 255 possible subnets in 192.168.x.x (e.g. 192.168.1.x). You can
put just that one in the Trusted zone, or you can put all of
192.168.x.x in it.
