Same here, I would also like to have the option of excluding my IP address from Site Stats. And if that option would be added, then please both for IPv4 and IPv6 addresses, which in the case of IPv6 would mean ranges. (Here in the Netherlands several internet providers offer IPv6 connections for ordinary domestic connections.)
I do have Google Analytics installed on my stat, and they just announced their interface would become easier to use. But whatever they do, I certainly appreciate the clean and clear Site Stats through Jetpack on WordPress.com.
