Google Data Centre List - June 2006

Just how many IPs are active anyway?

[g1smd]

I don't think I have ever seen a complete list of all the datacentres that Google has online.

I keep seeing short lists with just a dozen or so that people are trying at that time.

Please contribute any IP addresses that you know about which are not already on this list:

>> I scanned the 64.233.160-191.x addresses, and received over 1600 responses. <<

Oh yes, there are many IPs that get a response from Google, with a logo, and a "Server Error" message, like 66.102.11.40 and many others.

I have seen lists of bot IPs, and other lists too. I have been focussing only on IPs that allow you to search the web.

[claus]

>> server, port 80

A web server alone does not cut it. Google serves up many other things than search results.

Some of those will be Gmail, some google directory, some blogs, and then all kinds of other stuff. What you would want to identify would probably only be the subset that serves a search box.

[g1smd]

I think these are all the Class-C blocks that respond:

64.233.161.x
64.233.163.x
64.233.167.x
64.233.169.x

216.239.55.x - X
216.239.57.x
216.239.59.x
216.239.63.x

These IP addresses respond only for selected values of x, where x can be any one of these:

17, 18, 19, 44, 80, 81, 83, 84, 91, 93, 95, 99, 100, 101, 102, 103, 104, 107, 115, 133, 147, 184, 189, 214.

Not every single possible combination from this list is actually in use - but the vast majority of them are.

All of those that do respond give a Google search box labelled "Google English".

Items marked with an X are no longer in use.

.

Are there any more Class-C blocks in use?

Are there any other values for the final number that work?

[g1smd]

I also see 66.249.87.x mentioned in some lists, but those do not work at the moment.

[lgn1]

Im sure that Google is clustering servers also.

Rather than having a list of hundreds or thousands of individual Google servers, we should concentrate on grouping of servers, that show the same results.

Im sure Google does not roll updates out to one individual server at a time.

Thats my 2 cents worth.

[g1smd]

What I see happen most of the time is that if you query google.com or any other doogle country TLD, you are served something from x.x.x.99 or x.x.x.104 or x.x.x.107 or x.x.x.147 every time (even though many more than that exist), and over the course of a month or two you'll only ever see about 7 or 8 Class-C blocks (even though many more than that exist). So, that does appear to leave a very large number of IPs that you never see.

The question is, are those other IPs seen by people elsewhere instead, or are they another route in to the same servers, a backup address should the main one fail due to DNS failure or something?

[f123]

Wow g1smd! Thanks for all your research.

I'm still new to posting and this may be a pointless question, but do you know of any DC IP lists for Yahoo, MSN, Ask and/or DMOZ?

[g1smd]

I have seen a list for Yahoo. Google for it. :-)

No idea about MSN or Ask. The ODP has one IP only.

[g1smd]

What are these URLs?

http://gfe-ar.google.com/
http://gfe-fg.google.com/
http://gfe-po.google.com/

Where do they fit into things?

Are there any more like these?

[g1smd]

Reports of the demise of the old www-va.google.com style Google datacentre URLs were way too early.

They are over here instead, and have grown in number:
gfe-au, gfe-ar, gfe-bf, gfe-bp, gfe-bu, gfe-bx, gfe-cw, gfe-dc, gfe-ed, gfe-eh, gfe-ff, gfe-fg, gfe-gv, gfe-he, gfe-hk, gfe-hs, gfe-hu, gfe-ik, gfe-in, gfe-jc, gfe-jp, gfe-kc, gfe-kr, gfe-lm, gfe-lo, gfe-mc, gfe-nf, gfe-nz, gfe-od, gfe-po, gfe-py, gfe-qb, gfe-rn, gfe-ro, gfe-tw, gfe-ug, gfe-ui, gfe-va, gfe-wr, gfe-wx, gfe-yo

Several two-letter pairs match the old lists. Many are missing and there are very many new ones.

[g1smd]

There are 41 class-C blocks in my earlier list, and 41 URLs in the above "two letter" list.

Draw your own conclusions.

.

Additionally, as well as the gfe-cw.google.com type URLs, many of them also respond to these formats too:

gfe-cw2.google.com and gfe-cw3.google.com

[g1smd]

>> For those who are keeping track, this is probably a good point for a review. Here are all the datacenters that have been listed so far and perhaps a few more. <<

Actually, it was quite a bad time for a review, as the list you published doesn't include extra stuff that I have here, but not yet published, and now dozens of sites have copied that list, which is incomplete.

Additionally, I asked by PM if you could flag up the items in your list that are new and not already in my list. Please can you do that?

[g1smd]

Google China has its own DCs.

They use the following IPs for www.google.cn and these cannot be directly acessed by IP address from here:

66.249.89.160
66.249.89.161
66.249.89.162
64.233.189.160
64.233.189.161
64.233.189.162
66.102.7.160
66.102.7.161
66.102.7.162
72.14.203.160
72.14.203.161
72.14.203.162

Direct IP access results in a redirect to www.google.co.uk instead.

[colin_h]

Anyone else noticing that Google.co.uk is missing its cache links at the moment?

Beware that there are likely to be a number of additional active x.x.x.99 and x.x.x.147 and x.x.x.103 IP addresses that do not yet have a domain name assigned to them.

(*) Note that gfe-hs and gfe-ui both point to the same IP address at the moment, and that that address was the test "Big Daddy" datacentre.

I assume that gfe-hs (x104) and gfe-hs2 (x99) are the regular names, and they aliased gfe-ui (x104) on to it for testing purposes internally, as in gfe-ui.google.com as the full URL.

More to follow....
