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:
Some thoughts about the domain name itself. Google probably wanted to use 10e100, since that character string means 10 to the 100 power - in other words, a googol. Not sure why they settled for 1e100, because that only comes out to a measly 1.
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.

This has nothing to do with anything in particular, but 1e100 is the mathematical notician for 1 googol (1 followed by 100 zeros).

Just for the clarification 1e100 is the actual mathematical/scientific notation for googol and not 10e100

thanks you so much. I just stumble on idea to check netstat - here i found 1e100.net. Your article was great help to understand. Thanks again

10e100 = 1e101

Its interesting and ive added to 127.0.x.x to stop the feature? to stop the rest of the bots in the world finding me or preventing captcha on everything?

1 ^ 2 = 1 * 1 = 1 1 ^ 3 = 1 * 1 * 1 = 1 .... 1 ^ 100 = 1 * 1 .... * 1 = 1 1 ^ n ( for all n except 0 ) = 1

1e100 = 1 x 10^100

1E100 (or 1e100) is E notation for a googol. It represents 1 * 10^100, not 1^100

E isn't the same as "raised to the nth power." E means move the decimal place. 1e3 meanr go 1., 10, 100., 1000. and so on. 1e-3 would be .001

Also, 1^n = 1, even for 0, as n ^ 0 = 1

Like I like to think of googol as 1 followed by 100 zeroes, a practical unimaginably huge number

Oops. Like I like. LOL. Why practical? It's practical for illustrative purposes. Here is one example of how it can be used in teaching: "If two numbers having magnitue 1.0e100 differ by only 1.0e95, they may be close enough to be considered equal"(See http://teaching.idallen.com/cst8110/97s/floating_point.html for full text.)

the domain belongs to mark monitor. this company represents an evolution in the legitimization of spyware. check out their website... they decide who the goods guys and bad guys are (based on who is paying the bills) and arbitrarily attack anybody they want. it appears they are sniffing a lot of traffic around the world.

1e100 = 1 * 10^100

looks to be some basic maths errors there :)

That isn't E notation.

Eh, not mathematical, but scientific (i.e. a reflection of the limitation of representation).
