Use Python to easily convert IP addresses between integers and strings.


Everyone should have some experience. It is really a waste of space and performance for storing string-type IP addresses in the database, so cute people want to convert IP addresses to integer storage. INET exists in MySQL_ ATON (),INET_NTOA ()If the function is used to convert an integer from an IP address to a string, which of the following methods can be used in MySQL?INET_ATON (),INET_NTOA ()? There must be some methods ~

The method is as follows:

# Import the relevant module package import socketimport struct # convert the IP from string to integer type> int (socket. inet_aton ('2017. 0.0.1 '). encode ('hex'), 16) 2130706433 # convert an IP address from an integer to a string >>> socket. inet_ntoa (struct. pack ("! I ", 2130706433) '2017. 0.0.1'


In Python, regular expressions are used to verify whether a string is an IP address.

Def checkip (ip): p = re. compile ('^ (25 [0-5] | 2 [0-4] \ d | [01]? \ D ?) \.) {3} (25 [0-5] | 2 [0-4] \ d | [01]? \ D ?) $ ') If p. match (ip): return True else: return False
