IP addresses of the zone RU / SU

Hi, Habr!
A year ago, my hands itched, I had an idea to establish the correspondence of each domain name in RU and its IP.
What was done was scanned all this for almost 2 weeks.

First of all, this html-subdocument was born.
From it it became clear how many domains are placed by providers for 1 IP.
It was also possible to see what kind of badies are placed on the server of one or another provider.

But a year has passed, I wanted to return to this topic.
I rewrote the scripts to work in several streams and finished scanning the RU and SU zones in 2 days.

I will not overload the text with unnecessary letters, only numbers:
Search domains by IP (RU as of January 2009 and February 2010; SU - February 2010): mirror.serverstat.ru ; 2nd link (slow)
Top IP-addresses in IP format: number of domains: Server_Name (by PTR-rr) for the same zones and periods: link # 1 ; # 2
')
I hope this information will help you draw interesting conclusions and share them.

In the process of writing a post, an idea arose: How much IP does an average website have?
Answer (on the right the number of sites, on the left the number of IP)

  mysql> select ipcnt, count (ipcnt) from `ru` group by ipcnt order by ipcnt desc;  
 + ------- + -------------- +
 |  ipcnt |  count (ipcnt) |
 + ------- + -------------- +
 |  22 |  1 |
 |  21 |  1 |
 |  17 |  1 |
 |  16 |  1 |
 |  15 |  7 |
 |  13 |  2 |
 |  10 |  3 |
 |  9 |  9 |
 |  8 |  8 |
 |  7 |  9 |
 |  6 |  1318 |
 |  5 |  500 |
 |  4 |  5756 |
 |  3 |  713 |
 |  2 |  125869 |
 |  1 |  1893165 |
 |  0 |  605791 |
 + ------- + -------------- +
 17 rows in set (1.84 sec)

In addition to IP, the database also contains information on the date of creation of the domain and the registrar (for RU for 2 points: the end of January 2009 and the middle of February 2010; for SU only the last one), if you want to receive any sample based on this information interesting for the community , please write in the comments and my habrayschik, if possible, I will gladly provide.

PS about the serverstat.ru interface, please do not hit. It is created only to access this information.
