iterating over a list and printing

[Bart Nessux]

ip_list = []
inputFile = file('ips.txt', 'r')
ip_list.append(inputFile.read())
inputFile.close()
for i in ip_list:
    print "/sbin/ifconfig %s netmask 255.255.252.0 broadcast 
128.173.123.255 up" %i

The last line does not work. It prints the first part (/sbin/ifconfig), 
then the entire list of ips, then the second part (netmask 255.255.252.0 
broadcast 128.173.123.255 up). Any ideas on how to fix this? The desired 
results are to print a line for each IP.

/sbin/ifconfig IP1 netmask 255.255.252.0 broadcast 128.173.123.255 up 
/sbin/ifconfig IP2 netmask 255.255.252.0 broadcast 128.173.123.255 up
etc...
