Well, if a certain browser vendor let the browser deduce the
external IP address, then send out a UDP DNS PTR query for
<reverse-ip>.in-addr.browser-vendor.com to say, a large DNS
resolving cluster they also happen to be running, from a random
source address, once every so often, they could very quickly
build up a name-and-shame list of providers that don't do
proper filtering. Just saying.
