Fix what?  You really have me confused... there is nothing to fix when
your ISP assigns one block to dial-up and another block to ISDN, but
the RBL lists just block the whole range... for example:

  192.168.0.1 - 192.168.0.62 for ISDN (subnet mask 255.255.255.192)
  192.168.0.63 - 192.168.0.255 for dialup users

The RBL lists would block 192.168.0.0/24 instead of just the later
half of the range.

I don't ;)

Understandable really... I get plenty of spam originating from .cn/.tw
addresses.

That's an odd stance. Last time I checked (and as you stated), AOL
bounce mail to their own SMTP servers.

Adjusting the PTR DNS records doesn't stop you falling into the
mentioned brackets above (yes I know I used private address ranges as
an example) for example. It just changes your name when somebody does
a lookup. If you're blocking by IP range (which is what RBLs do),
names don't mean a thing.
