Gmail on IPv6 – buggy last account activity information.

Gmail Activity information by wahjava, on Flickr
I’m accessing Gmail’s web UI over IPv6 internet since they launched ipv6.google.com. Recently I’ve noticed that they made available Last account activity information. So I clicked on that link to see my last account activity and I’m surprised to see an IPv4 address instead of an IPv6 address (expected). The IPv4 address is, which is a class D address reserved for multicasting. So, is this some kind of IPv{4,6} portability bug in their code, or ipv6.google.com acting as a proxy for mail UI running on IPv4 servers with a class D address assigned, hmm…?
