Want to write a script to do the batch conversion from domain name to IP.

[Hongyi Zhao]

Hi all,

Suppose I've the entries like the following in my file:

------------------
116.52.155.237:80
ip-72-55-191-6.static.privatedns.com:3128
222.124.135.40:80
217.151.231.34:3128
202.106.121.134:80
211.161.197.182:80
hpc.be.itu.edu.tr:80
static3-117-183.worldinternetworkcorporation.com:80
------------------

Now, I want to convert the domain name to IP by using a python script,
e.g.,

ip-72-55-191-6.static.privatedns.com:3128

should be converted into the following form:

72.55.191.6:3128

any hints on this?

PyDNS might be a helpful library for writing such a script --
http://pydns.sourceforge.net/

Why not just use socket.gethostbyname?

Python 2.5.2 (r252:60911, Oct 5 2008, 19:24:49)
[GCC 4.3.2] on linux2

See the following errors I in my case:

Sorry for my carelessness. It's obviously due to the lack of the
socket module in my case.

Another issue is: how can I perform all of these steps in a python
script?

Those errors indicate that Python is not working correctly in your system.
You should fix it before going on.

Start reading the tutorial and working the examples:
http://docs.python.org/tutorial/
In a short time (maybe shorter than you expect) you'll manage enough of
Python to do this.
Come back when you have specific questions, or try the tutor list:

I use cygwin, I don't know whether the further discussion on fix this
issue is suitable for this group or not? If not, could you please
give me some hints on the newsgroups or maillists I should resort to?
