When I had an Android tablet, I noticed it was affected by this as well.
Something that brought it to light and casued me no end of trouble - BT Homehub (and I'm sure, many ISP's) router default DNS settings pointed to BT's DNS server, which in an effort to generate ad-based revenue would redirect to a search page if it couldn't resolve an address. Which is great, but what it meant, and how it was setup, meant that a DNS reply would be returned for any address, private, public, or utter rubbish - all 'unknown' records resolved to the IP of the web server BT were using for (instead of returning unknown) . It may be worth checking to see if there's similar at play here.
