I'm happy with "routing" as in directing traffic via DNS resolution. I doubt anyone here is confusing that.

I disagree. As a former network engineer the title "We're transforming internet routing" and subtitle "Rethinking Internet Routing" [my emphasis] makes me think of IP based routing first. I think they could have been clearer or picked a less grandiose title.

Don't get me wrong, on the surface this looks like a neat tool.
