I'm trying to find out IPv6 address from a string. I've done this on IPv4 part by using re.findall(re.compile('\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}'),addr). How can I modify this to IPv6?

Here's my string:

addr = "......IP address is 2001:0000:3238:DFE1:63::FEFB. SUbnet mask is.........."

Any help is appreciated. :)

Depending on your purpose, you might be interested in the [`ipaddress` module](https://docs.python.org/3/library/ipaddress.html#module-ipaddress) which is part of the stdlib in python 3.3+ and also [backported](https://pypi.python.org/pypi/ipaddress) for previous python versions. – Marty Dec 09 '17 at 05:14
as @marty suggested use ipaddress module . – Aaditya Ura Dec 09 '17 at 05:24
Are you trying to validate if a given string is an IpAdresse or do you have a long string which might include an IpAdresse? – user1767754 Dec 09 '17 at 05:42
@user1767754 I have a long string which include IP Address and words. – gonzalloe Dec 09 '17 at 05:48
Is the IP always surrounded by the same text? – user1767754 Dec 09 '17 at 05:50
Nope. FYI, I had successfully parse out IPv4 address from mystring by using `re.findall(re.compile('\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}'), addr)` – gonzalloe Dec 09 '17 at 05:52
Yeah the question is, can one string contain multiple matches? Ipv6 is way more complicated than IPv4 – user1767754 Dec 09 '17 at 06:06
It might be multiple matches. – gonzalloe Dec 09 '17 at 06:07
