node-proxy-addr - 2.0.6+~0.1.2-1 main

This module allows one to list and optionally filter remote addresses
of an incoming request, as populated by the HTTP X-Forwarded-For header.

It works with both IPv4 and IPv6 and can filter addresses using pre-defined
names like "loopback", "linklocal" or "uniquelocal" (which are expanded
internally into IP addresses or ranges), or using a custom function.
