"""Simple utility for building a list of local IPs using the socket module.
|
|
|
This module defines two constants:
|
|
|
|
|
|
LOCALHOST : The loopback interface, or the first interface that points to this
|
|
|
machine. It will *almost* always be '127.0.0.1'
|
|
|
|
|
|
LOCAL_IPS : A list of IP addresses, loopback first, that point to this machine.
|
|
|
|
|
|
PUBLIC_IPS : A list of public IP addresses that point to this machine.
|
|
|
Use these to tell remote clients where to find you.
|
|
