Back in December, I spotted a WebmasterWorld thread with a webmasters asking why Google is pulling in commands from 1e100.net, as opposed to Google.com. At first, I thought it was nothing and let the thread go.

But now, it appears that this is a significant domain. Back then, Tedster, the administrator at the forum said:

The Register today reported that this domain, 1e100.net, “is now visited by nearly three per cent of all net users, making it the 44th most visited domain on the interwebs.” The Register asked Google about this, and reported back:

Asked for comment, Google merely said the domain is used to “identify the servers on our network,” and it hinted that such identification involves reverse DNS lookup – the process of determining which domain name is associated with a particular IP address. Reverse DNS is often used by anti-spam services to verify email senders, but it’s also used a general means of ensuring a network is working as it should be working.

Might just be one of those geek factors, Google is so well for.
