ipaddress.IPv4Network

tomthirteen · (This post was last modified: Dec-17-2018, 08:18 PM by tomthirteen.)

Hello all,

I am trying to go through a file of editors and find the IP addresses of edits if given. Some are IP ranges, others are single IP. It seems to work well, but it does not complete the entire file. It gets to the fourth to last IP range and then stops, even though there are four more IP addresses left. Any suggestions? The last few IP's are not ranges.

Code:

with open("fr_block.txt", "r", encoding="utf8") as f:
    next(f)
    for line in f:
        newline = line.split()
        try:          
            net = ipaddress.IPv4Network(newline[2])
            for a in net:
                f2.write(str(a) + "\n")
        except:
            pass

don't use catch all exception. moreover you don't provide any feedback effectively you mask the error.
run

with open("fr_block.txt", "r", encoding="utf8") as f:
    next(f)
    for line in f:
        newline = line.split()        
        net = ipaddress.IPv4Network(newline[2])
        for a in net:
            f2.write(str(a) + "\n")

I guess you will get IndexError, assuming f2 is defined elsewhere in the code.

This won't work. I have text names too. The third column is the editors

that was not solution, but explanation what's going on.

Not tested but something like

with open("fr_block.txt", "r", encoding="utf8") as f:
    next(f)
    for line in f:
        line = line.split()
        try:          
            net = ipaddress.IPv4Network(line[2])
        except ipaddress.AddressValueError:
            print('{} is not valid ip'.format(line[2]))
            continue
        else:
            for ipaddress in net:
                f2.write(str(ipaddress) + "\n") # assuming f2 is defined elsewhere in the code

It raises an exception at the first IP address that's not a network (p.s. f2 is defined before. It's the file. It contains either a username, IP address or IP address with a range. I want only the IP addresses and IP addresses with ranges.

Error:

Traceback (most recent call last):
File "E:\Data\Languages\French\test\block.py", line 20, in <module>
net = ipaddress.IPv4Network(line[2])
AttributeError: 'IPv4Address' object has no attribute 'IPv4Network'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "E:\Data\Languages\French\test\block.py", line 21, in <module>
except ipaddress.AddressValueError:
AttributeError: 'IPv4Address' object has no attribute 'AddressValueError'

sorry, it's really late here. I overwrite ipaddress module with the variable name

with open("fr_block.txt", "r", encoding="utf8") as f:
    next(f)
    for line in f:
        line = line.split()
        try:          
            net = ipaddress.IPv4Network(line[2])
        except ipaddress.AddressValueError:
            print('{} is not valid ip'.format(line[2]))
            continue
        else:
            for ip_address in net:
                f2.write(str(ip_address) + "\n") # assuming f2 is defined elsewhere in the code

Here is how I test it

import ipaddress
items = ['blaba', '92.103.143.0/24']
for item in items:
    try:          
        net = ipaddress.IPv4Network(item)
    except ipaddress.AddressValueError:
        print('{} is not valid ip'.format(item))
        continue
    else:
        for ip_address in net:
            print(ip_address) # assuming f2 is defined elsewhere in the code

output

Hide/Show

Output:blaba is not valid ip

Thank you. It's still giving me the same result. It is not recognizing the last IP's as invalid, but it's not writing them either. Any help is greatly appreciated.

**buran** · Dec-17-2018, 09:33 PM

Unless you show your full code as well as the input file I don't have other ideas

tomthirteen · (This post was last modified: Dec-17-2018, 10:25 PM by tomthirteen.)

The code is not much different from what I've showed. The rest is below. I would attach the file, but I need to become a user. I can't figure out how to do that. Do you know how?

Thank you SO MUCH! I greatly appreciate it.

#change IP  ranges to ip addresses
import ipaddress
import re

#f = open("fr_block.txt", "r")
f2 = open("fr_block_2.txt", "w")

#next skips header
#limits date
#passes index into ip ranges and prints each ip
#except passes if not ip
#else ends the timestamp limit


with open("fr_block.txt", "r", encoding="utf8") as f:
    next(f)
    for line in f:
        line = line.split()
        try:          
            net = ipaddress.IPv4Network(line[2])
        except ipaddress.AddressValueError:
            print('{} is not valid ip'.format(line[2]))
            continue
        else:
            for ip_address in net:
                f2.write(str(ip_address) + "\n")

Since I can't attach, this is the last part of the file. It correctly handles the last network IP, but then stops, even though there are a few more IP addresses.

File attached. Thanks!

The script runs and process file till the end.
As you can see from the screenshot, it process 4786 rows (excluding the header)

The last ip is 158.64.55.65 on line 4668 and it's the last one in the output file. The output file is too big to upload it here (some 37 Mb), but you can see the last ip is that one

I don't see what else you expect from the script. Here it is with minimal changes

import ipaddress
 
with open("fr_block.txt", "r", encoding="utf8") as fin, open("fr_block_2.txt", "w") as fout:
    next(fin)
    for i, line in enumerate(fin, start=1):
        line = line.split()
        try:          
            net = ipaddress.IPv4Network(line[2])
        except ipaddress.AddressValueError:
            print('{} is not valid ip'.format(line[2]))
            continue
        else:
            for ip_address in net:
                fout.write(str(ip_address) + "\n")
print('\n\nTotal rows processed (excluding the header row): {}'.format(i))

If I have time will add second version, e.g. I would use csv.DictReader to read the inpyt file, etc.
