#PYTHON MAC ADDRESS VALIDATION CODE#
You can use this tool to make that code look pretty and readable so it is easier to edit. It is also common for Python to be minified or obfuscated. This tool is helpful for making the formatting of a file consistent. It is also common for multiple developers to work on a single project who have different formatting techniques. Often when writing Python your indentation, spacing, and other formatting can become a bit disorganized. There are many option to tailor the beautifier to your personal formatting tastes. The editor above also contains helpful line numbers and syntax highlighting. Or you can simply run all of the tests by specifying no arguments, so like: python script.Enter your messy, minified, or obfuscated Python into the field above to have it cleaned up and made pretty. You can run the script with test result and example arguments in the form of "=", so like: python script.py Fail=::1.2.3.4: pass=::127.0.0.1 false=::: True=::1 I also put together a Python script to test all of those IPv6 examples it's here on Pastebin because it was too large to post here. Return is_valid_ipv4(ip) or is_valid_ipv6(ip)Ġx0*)? In Python 2 you will need to explicitly convert the IP address string to unicode: ipaddress.ip_address(u'127.0.0.1'). This module is compatible with Python 2 and provides a very similar API to that of the ipaddress module included in the Python Standard Library since Python 3.3.
#PYTHON MAC ADDRESS VALIDATION INSTALL#
ValueError: 'foobar' does not appear to be an IPv4 or IPv6 addressįor Python 2, you can get the same functionality using ipaddress if you install python-ipaddress: pip install ipaddress ValueError: '277.0.0.1' does not appear to be an IPv4 or IPv6 address If you're using Python 3.3 or later, it now includes the ipaddress module: > import ipaddressįile "/usr/lib/python3.3/ipaddress.py", line 54, in ip_address However, like Dustin's answer, it will accept things like "4" and "192.168" since, as mentioned, these are valid representations of IP addresses. ValueError: invalid literal for long() with base 10: 'foobar' ValueError: '277.0.0.1': single byte must be 0 > IP('foobar')
The IPy module (a module designed for dealing with IP addresses) will throw a ValueError exception for invalid addresses. In my experience if the address is invalid you will get a result of 602 from the service. This service attempts to return the exact coordinates of the location you feed it, i.e. Submit the entire address to Googles geocoding web service. S.a.: ipaddress 1.0.17, "IPv4/IPv6 manipulation library", "Port of the 3.3+ ipaddress module", Not 100 perfect, but it should reject blatantly non-existent addresses. To install with pip: pip install ipaddress in Anaconda Python 2.7 & is included in Installer.
The backport from phihag is available e.g. Print('address/netmask is invalid: %s' % sys.argv)įor other versions: Github, phihag / Philipp Hagemeister,"Python 3.3's ipaddress for older Python versions", Print('%s is a correct IP%s address.' % (ip, ip.version)) From Python 3.4 on, the best way to check if an IPv6 or IPv4 address is correct, is to use the Python Standard Library module ipaddress - IPv4/IPv6 manipulation library s.a.
