List of PL IPv4 and IPv6 networks in various formats.

It is generated from the same database polish IRCnet servers use to generate their I-lines (access lines). As new networks come to life, their admins (or users) tell us to add them, hence I hope the list is quite complete. If you see any errors or omissions, let me know.

Due to repeated requests from IPv6 tunnel brokers I also prepared list of our K-lines for *@cidr ranges, so it can be used to deny tunnels requested for K-line evasion. These are only active K-lines for full IPv4 hosts or networks.

Should anyone care, here's also full list of our active K-lines.
