As has been pointed out, this is tricky.  A machine can have any number
of IP addresses, even if it has only one interface; which do you want?

If it's specifically dialup, and you're after the IP address of the
first modem connection then:

#!/bin/sh
if ppp-is-up
then
	ppp_to_ip
fi

> cat ppp-is-up
#!/bin/sh

exec ifconfig | grep ppp > /dev/null

> cat ppp_to_ip
#!/bin/sh
ifconfig -i ppp0 | head -2 | tail -1 | sed -e "s/[^0-9]*//" | sed -e "s/
.*//"


These will probably only work for Linux.
