推荐答案

这将使IP地址与端口号匹配.

This will match IP addresses with ports numbers.

match = re.findall(r'[0-9]+(?:\.[0-9]+){3}:[0-9]+', source)

如果要灵活地匹配不带端口的IP地址和带端口，可以使用:

If you want to make it flexible to match IP address without the ports and With the ports, you can use:

match = re.findall(r'[0-9]+(?:\.[0-9]+){3}(:[0-9]+)?', source)
