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:

Has anyone found logical groups for these datacenters yet? or Geo-targeting?

[LuckyGuy]

it is off topic: But how could you explain this:

ping google.de shows up 216.239.39.104
ping www.google.de shows up 66.239.85.104

Url google.de in browser redirects to www.google.de.

shouldn´t that be the same? or is a simple redirect?

[softplus]

>ping google.de shows up 216.239.39.104
>ping www.google.de shows up 66.239.85.104
Both are domain names that need to get resolved.

Once they are resolved, the server might issue a redirect or answer directly. But for that to happen, it will need to get resolved first.

you might get
google.de [ 216.239.39.104 ]
and get "please go to www.google.de"
and then the final response at
www.google.de [ 66.239.85.104 ]

It's a bit back and forth, but it works :-)

Post 27 should have said:

>> been listed so far and perhaps a few more <<

Can you separately list those that you have added that are not on my posted lists, because the list on my hard drive is already bigger than what is posted here, and my list also includes a lot of information about what is live, and what is history?

[g1smd]

Post 28 should have said:

That newer list hints that there may be yet more undiscovered IP addresses.

I think that I have now found most of them. There are more than a hundred.

There may well be a few more to be found yet.

.

I did a Google search for a few of the new IP addresses discovered and found several of them to be highly discussed in Chinese and other Asian language forums.

Maybe some of those IPs are never shown to US or European searchers.

[unreviewed]

>>Is this all the Class C blocks in use, or are there more?

[ws.arin.net...]

That list also includes Google’s IPV6 block,
2001:4860:0000:0000:0000:0000:0000:0000 - 2001:4860:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF

That block alone is 79 billion billion billion addresses.

Good luck on your endeavor g1smd. ;)

[g1smd]

I have no idea why they would need that many. Seems more than a bit OTT to me.

Anyway, thanks for the list. It confirms that we have probably found almost all of the current IP addresses that are in use right now, and that there are two other blocks to look at in the future.

[unreviewed]

>> I have no idea why they would need that many.

Three words, ISP.

[Komodo_Tale]

If someone knows PHP or Perl or such they could easily write a program to loop through each of the class c blocks and loop from 0 to 999 to test the last part.

I would do this myself except my outgoing firewall disallows pinging.

[g1smd]

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
216.239.32.0 - 216.239.63.255 - In Use

Only a few selected IP addresses are in use out of millions of possible combinations.

[gcc_llc]

Funny observation.

When I search with site:domain.com with no filter on I get 90k results.

When I search with a strict filter on I get 140k results.

Go figure.

> pinging

A ping will tell you if a server is at a given IP address (and responding), but it won't tell you if it's a web server.

Hasn't anyone done a port scan of the ranges? You'd only have to look at Port 80...

I scanned the 64.233.160-191.x addresses, and received over 1600 responses. I don't doubt that there are more servers in that range that I missed, since I had my timeout threshold set very low.

Am I about to post all 1600+ IPs? Hah, no - no one "reads" a post like that, and I'm sure it would count as bad netiquette. But, if you have 32KB free space in your StickyMail, then the list is yours for the asking...

---

A note to The Future

If this post is more than 2 or 3 weeks old, then chances are excellent that I've deleted the list. Data like this can go stale pretty quickly... Do a port scan for your own, up-to-date list.

[ogletree]

This thread [webmasterworld.com] has a lot of good videos that shed some light on this for me.

[straylite]

If you're trying to find out where Google's data centres are, searching the web for lists of IPs is just going to flood you with data.

Google, like other large companies is fairly well organised, and like every other Internet company has to have its IPs allocated to it by places such as ARIN (the American Registry for Internet Names). You can search ARIN by name, so:

[ws.arin.net...]

gets you all of the ARIN-registered netblocks for google, assuming they use the Google name everywhere:

Google Inc. GOOGLE (NET-216-239-32-0-1) 216.239.32.0 - 216.239.63.255
Google Inc. GOOGLE (NET-64-233-160-0-1) 64.233.160.0 - 64.233.191.255
Google Inc. GOOGLE (NET-66-249-64-0-1) 66.249.64.0 - 66.249.95.255
Google Inc. GOOGLE (NET-72-14-192-0-1) 72.14.192.0 - 72.14.255.255
Google Inc. GOOGLE (NET-209-85-128-0-1) 209.85.128.0 - 209.85.255.255

You can do this on other NCCs too, like APNIC, AfrNIC, RIPE and so on.

If you're looking for geographical locations, you could just cross-reference those addresses with some GeoIP data and you'd have a map. You could even use Google Maps to map google's IP addresses :)

Remember that the hierarchy of information is there - but it helps if you go top-down, instead of bottom-up...

[g1smd]

Thanks for the longer explanation of the hints posted in #36, though the post in #36 also links to a much longer list of ARIN IP assignments to Google. That has confirmed the bounds of possible addresses.
