Will the new canonical tag help with issues where you by accident (stupid editors linking to wrong addresses) have indexed sites by the IP address rather than hostname?

I’ll have to double check, but that is the sort of thing that you would like to be able to do; you’d like to take your IP address and put that over to your hostname. Now that I’m thinking aloud, we might consider the IP address different than the hostname, so we’ll have to confirm on that. But I don’t think it would hurt to go ahead and have that.

Ideally, that is the sort of thing that you don’t want your IP address to show up, you want your host/domain name to show up instead.

I think that would be a nice thing to do. I’m not sure whether we support it for IP addresses yet, but I’ll ask the guy that wrote and did the heavy-lifting on this code and see what happens.
