h1. 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. h3.
