IP-filter - It is a special file ipfilter.dat which contains IP-Ranges of anti-peer2peer organizations, corrupted data senders, hackers and resedved IP-Ranges. Which will be blocked. More info. IP-filter consists of: 1) Basic (Level 1) blocklist by Bluetack Internet Security Solutions. 2) Bogon list by CIDR Reports. 3) Fake servers list created and updated by me.
If you experience problems with the serverlist update (some servers filtered), please update ip-filter version on you emule - http://upd.emule-security.net/ipfilter.zip The old versions of ip-filter block some good servers such as Sharing Kingdom. So I recommend connect to the Kademlia-network, since it remained very few good servers. The majority of large eMule servers (eMule Serverlist N1,2 and eDonkeyServer No1,2) goes offline.
