[Leftz]

Hi We have devices ip address like this 10.1.1.2-4. Anyone can help to show python commands to let ip address like 10.1.1.2, 10.1.1.3, 10.1.1.4 ? or below, Thank you

10.1.1.2,

10.1.1.3,

10.1.1.4

Hello,

is this a duplicate post ? Since you accepted a solution to the same question below, is the problem still existing ?

Hi there,

See below for a first pass at an implementation, only limitation is it that it checks just that last octet for expansion:

IPs = ['192.168.1.1', '192.168.2.1-10']
expanded_ip_list = []
for ip in IPs:
    if '-' in ip.split('.')[3]:
        prefix = '.'.join(ip.split('.')[:3])
        high_low = ip.split('.')[3].split('-')
        r = range(int(high_low[0]), int(high_low[1])+1, 1)
        for x in r:
            expanded_ip_list.append('{0}.{1}'.format(prefix,x))
    else:
        expanded_ip_list.append(ip)

print(expanded_ip_list)

gives:

['192.168.1.1', '192.168.2.1', '192.168.2.2', '192.168.2.3', '192.168.2.4', '192.168.2.5', '192.168.2.6', '192.168.2.7', '192.168.2.8', '192.168.2.9', '192.168.2.10']

cheers,

Seb.

Thanks all for your reply

@Georg Pauwen its partially resolved. Based on my understand to that reply, my question was a little too bigger, so that I posted unresolved part in this thread. 

@Seb Rupik It looks work. let me try it

Adding to other option as below :

import re
ip='10.1.1.2-4'
x=re.split('-',ip)
y=re.split('\.',x[0])
first=int(y[3])
last=int(x[1])
list_ip=[]
for i in range(first,last+1):
temp=y[0]+'.'+ y[1]+'.'+y[2]+'.'+ str(i)
list_ip.append(temp)
print(list_ip)

COOL, thank you!!

"import re" in your comment, how can we get "re" ? what does "re" look like?
