Does "set_real_ip_from" support IPv4 only?

Looks like Nginx doesn't support IPv6 in the set_real_ip_from declaration: Wondering if it even matters w/Cloudflare?

Hi, I'm confused, I get this error by entering an IPv6 address in the set_real_ip_from directive: nginx: [emerg] "set_real_ip_from" supports IPv4 only in /usr/local/nginx/conf/nginx.conf:65 But according to the changelog, that directive should support IPv6 since nginx 0.8.22: Changes with nginx 0.8.22 03 Nov 2009 [...] *) Feature: the "set_real_ip_from" directive supports IPv6 addresses in request headers. [...] My nginx version: 1.0.8 Is the changelog referring to something else or is this a bug? Thank you, Andrea Posted at Nginx Forum: http://forum.nginx.org/read.php?2,216320,216320#msg-216320
