Config files with fixed fields are evil. Really evil.

Please pick another format:

interface {
	dev = eth0
	secondary = yes/no
	ip = foo
	netmask = bar
	route = baz
}

or

interface.eth0.ip = 192.168.1.1
interface.eth0.mask = 255.255.255.0

etc. The last on is more easy to script;

CONF=/etc/ip.conf

INT="`sed -n -e 's/^interface\.\([a-z0-9\-]\+\)\..*$/\1/p' < $CONF | sort -u`"
echo $INT
for i in $INT
do
        ip=`sed -n -e "s/^interface.$i.ip.*=\(.*\)\$/\1/p" < $CONF`
        mask=`sed -n -e "s/^interface.$i.mask.*=\(.*\)\$/\1/p" < $CONF`
        echo "interface $i, ip $ip, mask $mask"
done

But this is SLOW. It'd be better to do it in perl. Or awk, maybe.
