I have a server with access to 9 different IP addresses that I want to use for different purposes and I wish to keep them separated. I am going to be doing my work using UrlLib2, is there a way I can specify which IP address I am using through Python?

I am not sure if I am being completely clear, let me try and give an example. Let's say I have 9 programs that connect to the web and retrieve data each hour running automatically as a scheduled task. If I want each program to run on a separate IP address, is there a way within Python I could specify which IP each program connects to when it goes to retrieve data from the web?

Thanks,
Rob

One possibility, depending on how you run your tasks, is to pass the IP address on the command line, thusly: C:\Work>blort.py 10.3.21.109 . The IP address would show up in the program as sys.argv[1] in this case:

C:\Work>type blort.py
import sys

print sys.argv

C:\Work>blort.py 10.3.21.109
['C:\\Work\\blort.py', '10.3.21.109']

The IP address is of type string and of course you could just as easily use a node name, if it is known to your server.

If each program has a different name, you could even just check sys.argv[0] to see what named program you're running, and select the appropriate IP address for that program name.

If this doesn't make any sense to you, then I probably didn't understand what you are trying to do.

Thanks for the reply. It makes sense but it's not exactly what I was asking. I know the IP's ahead of time and can keep them hard-coded in the program. What I don't understand how to do is use that particular IP address to make a connection (as opposed to my default IP) when going to a webpage to retrieve data.

So instead of the standard URLLib2.urlopen('www.examplepage.com'), I want a way to specify which IP address is used to make the connection that goes and accesses 'examplepage.com'. Sorry, I might not be doing a great job of explaiing it, is this more clear?
