bogon filtering question

[Vidiot]

I'm currently running RH 7.1 (moving to Fedora Core 3 soon).  I received
the following e-mail:

**** start quote *****
We are Telewest Broadband AS5462 , a United Kingdom based cable ISP with
almost 500k cable internet customers. Customers of ours are complaining =
that
they cannot access www.vidiot.com when routing from one of our new IP
ranges (82.32.0.0 /12). However this site is accessable from PCs using a
different source IP address.

The most common cause of this is an out of date bogon filter (earlier =
than version 1.6)
These static filter lists don't reflect the assignment of the the =
82.0.0.0/8
range by IANA to RIPE for European IP allocation. RIPE have since =
allocated
the 82.32.0.0 /12 range to us, please refer to:

http://www.ripe.net/perl/whois?form_type=3Dsimple&full_query_string=3D&se=
archtext=3D82.32.0.0%2F12=20

More information on bogon filter versions : =

Please can you investigate this problem & remove/update this static =
bogon list from your router/web server, as you filtering a 'live' block =
of IP!

What is this guy talking about?  I know that I've not done anything on
purpose to block any IPs.  Is there a file somewhere that I can look at?

Thanks for any pointers.
