added: function to sort public and private IPv4

[BeardedInfoSec]

This function takes in both public and private IPv4 addresses and returns the public IPs. This prevents sending internal IPv4 address for enrichment

[HarlodHolt]

You could use ipaddress library and is global and or other boolean checks, something like:

import ipaddress

Define an IP address (IPv4 or IPv6)

ip1 = ipaddress.ip_address("8.8.8.8")
ip2 = ipaddress.ip_address("192.168.1.1")
ip3 = ipaddress.ip_address("2001:4860:4860::8888")
ip4 = ipaddress.ip_address("fe80::1")

Check if the IP addresses are global

print(f"{ip1} is global: {ip1.is_global}") # Expected: True
print(f"{ip2} is global: {ip2.is_global}") # Expected: False (private IP)
print(f"{ip3} is global: {ip3.is_global}") # Expected: True
print(f"{ip4} is global: {ip4.is_global}") # Expected: False (link-local address)
