In need of an IP address on-the-fly that appears to be valid? Try this:

View Code PYTHON

from random import randrange   def generateIP(): blockOne = randrange(0, 255, 1) blockTwo = randrange(0, 255, 1) blockThree = randrange(0, 255, 1) blockFour = randrange(0, 255, 1) print 'Random IP: ' + str(blockOne) + '.' + str(blockTwo) + '.' + str(blockThree) + '.' + str(blockFour) if blockOne == 10: return self.__generateRandomIP__() elif blockOne == 172: return self.__generateRandomIP__() elif blockOne == 192: return self.__generateRandomIP__() else: return str(blockOne) + '.' + str(blockTwo) + '.' + str(blockThree) + '.' + str(blockFour)

We’re skipping 10.x.x.x, 172.x.x.x and 192.x.x.x due to the fact that these are reserved address. RFC 1918

Version 2:

An elegant solution to serve the purpose of generating a random IP provided by Ben (explanation of changes listed in the comments below):

View Code PYTHON

from random import randrange if __name__=="__main__": not_valid = [10,127,169,172,192]   first = randrange(1,256) while first in not_valid: first = randrange(1,256)   ip = ".".join([str(first),str(randrange(1,256)), str(randrange(1,256)),str(randrange(1,256))]) print ip

Can be run from the command line or in another application. Built for Python 2.4 with pyCURL
