Safe Browsing

I keep a log on my router to track network activity originating from within my firewall -a healthy dose of paranoia combined with the fact that there still is one virtual PC running Windows on my network. And so from time to time I check the logs, not so much the detail but the quantity. All good. Today, on a fresh log, before I really started doing anything I did notice one odd detail: TCP Packet – Source:192.168.10.8,50096 Destination:209.85.227.109,25 – [SMTP rule match]

Odd because I hadn’t sent out any emails yet. Odd because that’s an unfamiliar IP address (even I did send out emails). Odd because I send emails over SSL (a different port entirely). And so the trace went:

* A quick check on the IP revealed the domain: 1e100.net and location Los Angeles. Definitely nothing I’m associated to. I think.
* A Google search (oh the irony) on 1e100.net and it turns out, this is a Google address.
* Your browser sends out “relatively” anonymous data to Google about your browsing habits- at least something like that: Safe Browsing Policy
