Actually it's pretty common for residential customers to have multiple subnets,
one wired and one wireless, even if they're both NAT'd to 192.168.x.x.
They may may or not be doing anything with the wired subnet,
and their wireless router may also be providing a wired subnet bridged
with the wireless,
and it's all happening in little consumer-appliance boxes that work by magic,
but it's out there.

Note that this isn't my regular email account - It's still experimental so far.
And Google probably logs and indexes everything you send it.
