We've written a Firefox Extension that displays the AS Number of every
website visited along with some additional interesting information. All
data is updated daily and the prefix to AS number mapping is from a DFZ
BGP feed.
You can download the extension here (a screenshot is available too):
http://www.asnumber.networx.ch
If you have any feedback, comments or feature requests please contact
me either directly or at <asnumber at networx.ch>. We are working on providing
a lot more information on the RIR IP address delegations but need fully
access to all RIR's whois records for that. I've completed all paperwork
last week and we should receive full access in the near future.
Another thing I want to do is to show the number of RBL (Spamhaus, etc)
listed IPs per AS. Contacting those RBLs is rather difficult and any help
to discuss this directly with the RBL administrators is appreciated.
Another request: So far we've got data servers in Europe and USA but
none in Asia-Pacific. If you are able to host either a dedicated or
shared (vmware/xen) FreeBSD server in Japan or South Korea with excellent
inter-Asia connectivity please contact me directly.

That sounds useful. As would be the possibility to block access to
sites that are so listed (in the same way that software installation
by unauthorised sites is blocked until specifically enabled)

That's certainly not been my experience and if you are still having
problems I suggest you write to me and I'll forward the request.

It will be a few days before I can look at the code, but I don't see a
privacy policy on the web page. What, if anything, is done with the
data collectible by your servers?

Odd, I can see one (and it is in the extension too)
Privacy:
The extension transmits the IP address of the server of every website visited.
No cookies are set or read from the ASNumber server and no per-user or browser
tracking or logging is done. Only aggregated statistics on the popularity of the
the looked up AS Numbers are computed. No information is made available to third
parties.

Look again, we have a privacy policy since day one. It's contained in
the extension 'about' box as well.

Since I'm one of the few people who has this data, I can tell you that actual 'number' is not as usefull as it may seem. There are different
RBLs with different focus and point of view and while some list individual
ips and live for a few days, others list ip blocks (and sometimes entire allocated block) can exist for months and years and are result of manual research. The first one causes a lot highier number in ASN RBL listings but underscores significance of the block listings.
My apologies -- I was looking quickly, and looked in the typical places
people tend to bury such things. I overlooked a prominent mention!

I'd like to inlcude a category in the ASNumber tooltip which lists
the number of listed IPs within that AS per RBL. It'd look like this:
SBL: 5835/5
XBL: 2645/3
SCBL: 3864/4
[numbers made up..., the second number is the average of listed IPs
per /24 announced by the AS]
Entire netblocks do not count as one but as many IPs they span.
