This thread follows on from the 2006 June thread at [webmasterworld.com...] and the 2006 September thread at [webmasterworld.com...] which list the many other IP addresses already found.

Older Google Datacentres (closed down many years ago):

216.239.33.nnn - www-ex - Gone a very long time ago.
216.239.35.nnn - www-sj - Gone a very long time ago.
216.239.41.nnn - www-fi - Gone a very long time ago.
216.239.55.nnn - www-zu - Gone a very long time ago.

66.249.87.nnn - gfe-lo/lo2 - Not Responding for a Long Time.

These are the major IP ranges that Google have:

8.6.48.0 - 8.6.55.255
64.68.80.0 - 64.68.87.255
64.233.160.0 - 64.233.191.255
- In Use
66.102.0.0 - 66.102.15.255 - In Use
66.249.64.0 - 66.249.95.255 - In Use
72.14.192.0 - 72.14.255.255 - In Use
209.85.128.0 - 209.85.255.255 - In Use
216.239.32.0 - 216.239.63.255 - In Use

Back in 2006 I showed that Google used approx 44 Class C blocks for their search operations and postulated that this corresponded with 44 datacentres (or at least 44 "server rooms").

Google search can be accessed in several different ways:

There is of course, google.com and all the various country google TLDs.

Next there is the direct IP address. There are several thousand of those, as listed below.

There used to be access at a URL like www-xx.google.com but those were replaced in 2005 with the newer gfe-xx.google.com system.

Finally, there is the direct alias per-IP address, all like xx-in-fnn.google.com where xx is the same letters as from the GFE name, and nn is the last octet of the IP addesss (like 107 from 66.102.9.107 and so on).

Notes:

On each Class-C block, there are several dozen IP addresses that are active. These usually end in 17, 18, 19, 44, 80, 81, 83, 84, 91, 93, 95, 98*, 99, 100, 101, 102, 103, 104, 105*, 106*, 107, 115, 133, 147, 184, 189, 210* and 214 (* Note: .98, .105, .106, & .210 seem to be no longer accessible). These show results from the "Google English" search screen.

Each Class-C block also has a two-letter GFE alias. These are always mapped in a specific way. For these, gfe-xx always corresponds to xx.xx.xx.104, most blocks also have gfe-xx2 which is xx.xx.xx.99 and a few also have gfe-xx3 which is xx.xx.xx.147. Finally, and for a very few, there is gfe-xx4 which is always xx.xx.xx.103. The search screen is simply announced as "Google" without the "English" logo.

Matt Cutts confirms that all the data at all of the IP addresses within one Class-C block should usually be the same, as typically they are all the same datacentre.

209.85.195.nnn - gfe-rg/rg2 - (access by direct IP address and by rg-in-fnnn.google.com URL format only - where nnn is 107,104,99 (but not 147,103), etc - NO ACCESS by GFE name).

Those without a GFE name or which resolve only by direct IP address are the most interesting. Could they be from a datacentre that is very newly online and therefore not yet fully commissioned?

In 2005, people were listing only 56, or so, IP addresses spread over about 18 Class C blocks.

At that time, Google did have more online (not much more though), but people just hadn't yet discovered them.

Things have changed a lot since then.

Curses to the short edit-post window.

Corrections and additions.

-----------------------------

In the third post, replace this:

209.85.129.nnn - gfe-fk/fk2/fk3
209.85.133.nnn - gfe-?/?2/?3
209.85.135.nnn - gfe-mu/mu2/mu3/mu4
209.85.139.nnn - gfe-?/?2/?3
209.85.143.nnn - gfe-?/?2/?3

with this:

209.85.129.nnn - gfe-fk/fk2/fk3
209.85.133.nnn - gfe-an/an2/an3
209.85.135.nnn - gfe-mu/mu2/mu3/mu4
209.85.139.nnn - gfe-pr/pr2/pr3
209.85.143.nnn - gfe-ti/ti2/ti3

-----------------------------

In the third post, before "Matt cutts confirms...", add:

For each gfe-xx.google.com search box, the same data can also be reached at gfe-xx1.google.com as it resolves to the same IP address.

-----------------------------

In the fourth post, in the section Google Datacentres No Longer In Use, replace this one:

209.85.155.nnn - gfe-?/?2/?3/?4

with these two:

209.85.155.nnn - gfe-ht/ht2/ht3/ht4
209.85.199.nnn - gfe-rv/rv2/rv3 - (Found in other lists)

-----------------------------

In the fourth post, add this closing text after the final entry in the list:

I must add that "no longer in use" means "no longer in use for search". While some Class C blocks have completely disappeared, some of the above now resolve to the Google Directory, or to Gmail, or to some other Google services instead.

New for 2008 - A Complete New IP Range:

Google was allocated a completely new IP block, just over a year ago, at 74.125.0.0 - 74.125.255.255 and has already started to populate it:

74.125.19.nnn - gfe-cf/cf2/cf3/cf4 - (access by direct IP address and by cf-in-fnnn.google.com URL format only - where nnn is 107,104,99,147,103, etc - NO ACCESS by GFE name).
74.125.39.nnn - gfe-fx/fx2/fx3/fx4
74.125.43.nnn - gfe-bw/bw2/bw3/bw4
74.125.45.nnn - gfe-yx/yx2/yx3/yx4
74.125.47.nnn - gfe-yw/yw2/yw3/yw4
74.125.65.nnn - gfe-gx/gx2/gx3/gx4
74.125.67.nnn - gfe-gw/gw2/gw3/gw4
74.125.77.nnn - gfe-ew/ew2/ew3/ew4
74.125.79.nnn - gfe-ey/ey2/ey3/ey4
74.125.93.nnn - gfe-?/?2/?3/?4
- (NO GFE name allocated - direct access by IP address only - where nnn is 107,104,99,147,103, etc).

These ten new Class C blocks represent another significant expansion of usage. They could have been online for anything up to a year, but my feeling is that they are mostly only a few months old.

Those without a GFE name or which resolve only by direct IP address are the most interesting. Could they be from a datacentre that is very newly online and therefore not yet fully commissioned?

Back in 2006 I showed that Google used approx. 43 Class C blocks for their search operations and postulated that this corresponded with 43 datacentres (or at least 43 "server rooms") active.

So, about 43, then 41 (when some fell out of use), then 47 (when new ones were discovered) Class C blocks were in use in mid-late 2006.

Since the 2006 lists were produced, 11 more have fallen out of use, and 34 new blocks have come online.

Going back a little further; in the last two years they have therefore closed about 11 of the older server farms (mostly in the older 66.102.nnn.nnn and 216.239.nnn.nnn Class C blocks). They have also opened 28 more in the 209.85.nnn.nnn range, and 10 more in the 74.125.nnn.nnn range, at the same time.

There are currently 70 Class C blocks in use, and the current system of allocation allows for a maximum of 288 such blocks to be brought in to use at full capacity.

When you take into account the individual GFE names like gfe-ro and gfe-pn3 there are approx. 204 of those active at present. Their current system allows for 1152 of those to be allocated, at a maximum of four per Class C block. Some blocks use less, but most new blocks seem to come online with four GFE names resolving these days. However, their naming convention has room for 2704 GFE entries, so there is plenty of room for expansion.

Although not a directly useful measure, the number of individual directly accessible IP addresses in use is already in excess of 1400.

The number of servers at Google appears to have almost doubled in the last two-and-a-bit years alone.

Good list g1smd. I wonder if anyone is seeing significant differences among any of the English language data centers.

For new sites, or for new pages added to existing sites, there can be considerable differences and many days before they are even close to being synchronised.

For unchanging sites, there are not so many differences, though several IP ranges are always in use testing new things out - which range that is, differs from week to week.

So, how many servers are Google installing, and what sort of configurations are they in?

Elsewhere, there is speculation that a cluster consists of around 1200 or 1800 servers, but what is a cluster?

In recent times Google has installed a lot of new hardware, some USD 3 Billion worth, and there are some patterns apparent in the naming schemes.

For each GFE name coming online there are normally four at a time, like gfe-cf, gfe-gf2, gfe-cf3, gfe-cf4.

Recent work has also seen these names coming online in pairs, with adjacent lettering, and adjacent IP addresses, like gfe-yw and gfe-yx as well as gfe-gw and gfe-gx and additionally gfe-ew and gfe-ey for example.

Could it be that these pairs are within the same building, with a building therefore containing 8 of these clusters?

As for the GFE names, anyone want to hazard a guess at how they are allocated?

da = The Dalles?
ff = Frankfurt?
cg = Chicago?
br = Berlin?

Google recently allocated GFE names to the new servers (listed above) which have been on test for a few months:

209.85.163.nnn - becomes gfe-el/el2/el3/el4

209.85.237.nnn - becomes gfe-yr

74.125.93.nnn - becomes gfe-qw/qw2/qw3/qw4
