I couldn't find this request in the list of recent threads so here goes:

Provide a way to load a large block of IP numbers into the filtered hosts list. Loading them in one at a time can take forever when one has a large list to be added.

The corrolary to the above is for somebody to put together an annotated list of the RIAA IP numbers. I got only about a fifth of the way through the list after hours and hours of whois sessions.

Trying to block the ranges of IP addresses owned by the RIAA is hopeless since they likely outsource the analysis of file sharing to companies like NetPD or Media Enforcer. And those companies probably have anonymous nodes on Road Runner cable modems or other major broadband networks.

What's needed is for limewire to 'learn' IPs that are:
- High on the response list (say "I have it")
- But never really send anything

are bogus and filter them out

Also:
If there was a central blacklist db of IPs (like MAPS/ORBS for open relays) limewire could query it.

But as a first step, the ability to block a full range of IPs ala 65.14.0.0/16 would help a lot.

You can already block a range of IP addresses!
Why not just entering these data to block invalid or local addresses:

0.*.*.*
10.*.*.*
127.*.*.*
172.16.0.0/255.240.0.0
192.168.*.*
224.0.0.0/224.0.0.0

Note there are 2 syntaxes supported to specify a mask, one with stars matching any byte value in the IP, and one that supports an IP mask in dotted notation (needed when the network mask length is not a multiple of 8 bits).

Currently the bit-length notation for masks and and short notations for network addresses are not implemented, so the following is refused:

0/8
10/8
127/8
172.16/12
192.168/16
224/12

If you want to copy paste a lot of addresses, you need to edit your "limewire.props" settings file, and modify the setting of BLACKLISTED_IP_ADDRESSES. If a line is too long, you may wrap it, but don't forget the ";" separator between addresses.
