Conversion from IP string to integer, and backward in Python

Question

i have a little problem with my script, where i need to convert ip in form \'xxx.xxx.xxx.xxx\' to integer representation and go back from this form.

def ipto         


        

Answer 1

It can be done without using any library.

def iptoint(ip):
        h=list(map(int,ip.split(".")))
        return (h[0]<<24)+(h[0]<<16)+(h[0]<<8)+(h[0]<<0)

def inttoip(ip):
       return ".".join(map(str,[((ip>>24)&0xff),((ip>>16)&0xff),((ip>>8)&0xff),((ip>>0)&0xff)]))

iptoint("8.8.8.8") # 134744072

inttoip(134744072) # 8.8.8.8
