IPv4 mapped addresses¶
If IPv6 is enabled (
server.use-ipv6 in your config) and your operating system has not enabled "bindv6only" (
sysctl net.ipv6.bindv6only or
sysctl net.inet6.ip6.v6only), lighttpd binds to an ipv6 socket and accepts ipv4 connections on it. This results in IPv4 mapped addresses in the access.log like "::ffff:127.0.0.1".
Debian enables ipv6 by default if it detects support for it; so if you don't need IPv6 you should disable that script in your lighttpd.conf; if you need IPv6 and don't like the mapped addresses you have to enable "bindv6only" and bind to the IPv4 address(es) and IPv6 address(es) yourself.
