Hello, tomorrow is world IPv6 day [1]. If I have read correctly, Wikimedia is intending to participate in the test day. I was wondering if that extends to the toolserver as well and in particular to the tile server? I suspect mod_tile should mostly be agnostic to which IP version apache uses, so hopefully it should just work in most cases. However, I did add the bandwidth throttling code a while back that is definitely not IPv6 safe. It is used to limit the number of tiles a single IP can download, to prevent heavy tile scrapers to abuse the tile server. It's hashing function for the per IP token bucket that is IPv4 specific. However, if that function is not enabled, it should hopefully not affect the rest of mod_tile. Has anyone tested mod_tile with IPv6? Thank you, Kai [1] http://www.worldipv6day.org/
