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 IP2 netmask 255.255.252.0 broadcast 128.173.123.255 up

This line just reads the whole file into the first element of the list.
Put "print ip_list" here to confirm this to yourself.
You need to loop over the file with the optional "size" parameter set or
by using inputFile.readl ines() if ips.txt is one IP address per line.

You just added the entire contents as a single element to ip_list
To iterate over the indiviual lines, you should go
for i in file("ips.txt") :
print "/sbin/ifconfig %s netmask 255.255.252.0 broadcast 128.173.123.255
up" %i

You are reading the entire file in one big string and append it to the list
which will always have one big item.
inputFile.close ()
for i in ip_list:
print "/sbin/ifconfig %s netmask 255.255.252.0 broadcast
128.173.123.255 up" %i

Assuming the file contains IPs one at a line, either initialize
ip_list = inputFile.readl ines()
or entirely omit the intermediate list:
(untested)
for line in file("ips.txt") :
print "/sbin/ifconfig %s netmask 255.255.252.0 broadcast 128.173.123.255
up" % line.strip()
strip() removes any leading/trailing whitespace including the newline
character at the end.

You probably meant something like this (untested):
inputFile = file('ips.txt', 'r')
ip_list = inputFile.readl ines() # Note readlines() rather than read()
inputFile.close ()
for i in ip_list:
print "/sbin/ifconfig %s netmask 255.255.252.0 broadcast 128.173.123.255 up" %i
If you really do need to create ip_list up front and append to it,
you should use extend() rather than append() - see the "mutable
sequence types" documentation for details.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
