Hello, this if my first post here.

This is probably nothing strange at all and common, but I've never seen It before In the years I've been doing this.

It appears that from the Google main office someone performed a site:search on one of my domains. Has anyone else ever seen this?

It's spoofed.

Do a traceroute (tracert 66.245.85.69 in a command window) and you'll find the IP is an Earthlink IP assigned to Mindspring DSL users.
