www.google can get its results from a server, via a load balancing arrangement, from any of 9 datacentres.
Each datacentre has a nominal IP address - and a specific address for the machine which you connected to - so you can tell which datacentre is providing you the data.
7 datacentres are showing 661K yahoo links, on these IP addresses:
www-ex is 22.214.171.124
www.va is 126.96.36.199
www-dc is 188.8.131.52
www-ab is 184.108.40.206
www-in is 220.127.116.11
www.zu is 18.104.22.168
www.cw is 22.214.171.124
2 datacentres are showing 617K yahoo links on these IP addresses:
www-sj is 126.96.36.199
www-fi is 188.8.131.52
At the moment, I'm seeing:
www at 184.108.40.206 (ie www-dc provided the results)
www2 at 220.127.116.11 (ie www-sj provided the results)
www3 at 18.104.22.168 (ie www-sj provided the results)
....and its been pretty much like that for the past week [webmasterworld.com...]
Nothing has changed - not that I can see anyway.....
Do your own research, your mileage may vary etc
www-ex ¦ 216.239.33.*
www-sj ¦ 216.239.35.*
www-va ¦ 216.239.37.*
www-dc ¦ 216.239.39.*
www-fi ¦ 216.239.41.*
www-ab ¦ 216.239.51.*
www-in ¦ 216.239.53.*
www-zu ¦ 216.239.55.*
www-cw ¦ 216.239.57.*
www2 and www3 point to www-sj at this time.
Those people who keep saying SJ is moving to www, you're wrong. It's not SJ that's moving it's you getting forwarded to the SJ or FI data center. Those data centers aren't just there for Google to test out indexes. Real people are using them to query the index. Since the newer indexes are only on 2 of 9 data centers, the chances of some googler getting the new index is probably 1/4.5.
The IPs you provided are the nominal published DNS IPs
eg WWW-IN.GOOGLE.COM is 22.214.171.124
(they all nominally end with 100)
The IPs I listed were from a traceroute, which said that the server I got was 126.96.36.199 at WWW-IN.GOOGLE.COM
The best analogy is that its like a rotary dial group - there is a nice rounded 'published' number - and there are any number of 'unpublished' lines - ie the DNS shows a published number - I'm watching the actual line numbers. As the difference shows - DNS is nominal - you'll aways get that datacentre on the "DNS number" - I wanted to see which 'lines' they are actually using. Because I think we will see the world of a continious update soon [webmasterworld.com...]
So - your IP list is correct - for published nominal DNS IPs - I have been watching the traceroute IPs.
I wouldn't be surprised to see SJ show up at other data centers first, and then to start applying the newer data/filters after that.
So does that means FI is first data center (and the only for now) that get the data from SJ and is applied with newer data + filters?!
FI got newer data because the total results are greater than SJ.
FI has spam filter because a lot of sites is missing!
There are strange things happening in FI because it block my site from appearing with CERTAIN keywords - should I call this the SEMI-PENALTY?!
There are no dirty tricks on my site, just keywords blocked are usually used in anchor text. A NEW FILTER?!
One of my Keywords is jumping from 7th to 4th and back again.
AthlonInside - I have also noticed that pages are not appearing on certain keywords :( - strange perhaps their is a filter if the density is to high? - this is a complete guess though.
I think those 216.239.48.* and 216.239.47.* addresses are just IP routers. You can't actually perform a query on any of them.
Check with allinanchor, and also a unique string from those pages. Google may have lost your inbound anchor text like they did with a site of mine. If so, you may just be buried very far down in the SERPs.
