python code wanted: grep IP address

[snippsat]

There's a ipaddress library that would validated correct for both IPv4/IPv6.
So i would think of just to use regex to get IPv4/IPv6 address whole of out text,then use ipaddress for validation.
Example.

>>> import re
>>> import ipaddress
>>> 
>>> s = 'foo8.8.4.4bar'
>>> ip = re.search(r'(\d.*\d)', s).group(1)
>>> ip
'8.8.4.4'
>>> ipaddress.ip_address(ip)
IPv4Address('8.8.4.4')

# Not valid 
>>> s = 'foo8.256.4.4bar'
>>> ip = re.search(r'(\d.*\d)', s).group(1)
>>> ipaddress.ip_address(ip)
Traceback (most recent call last):
  File "<string>", line 449, in runcode
  File "<interactive input>", line 1, in <module>
  File "C:\python37\lib\ipaddress.py", line 54, in ip_address
    address)
ValueError: '8.256.4.4' does not appear to be an IPv4 or IPv6 address
