Wonder what moron came up with the idea that Yahoo! should use addresses in the multicast range 224.0.0.0/4 in the webmail Received headers.
There are other places/reasons that this happens. For example, take a look at CloudFlare's "Pseudo IPv4" implementation that kicks in when a IPv6 client is served content from their proxy from a IPv4-only host.
