What's this 40% unknown?

[BkkCoins]

It refers to blocks generated from IP addresses that blockchain.info doesn't have on file. You can look at the details and see the IP addresses but he doesn't have any records of who they are. But he only has IPs for most of the well known big pools. So this would me an aggregate of many smaller pools, solo miners and any other various sources. It doesn't appear to indicate one controlling party though.

I think a good portion of this is probably abcpool.co   they have ~500 Ghash, but are not listed.

Bitminter has 90 GH/s and isn't listed.
p2pool has 90 GH/s and isn't listed.

Really if sites are going to make charts like that they need to break out each pool w/ 1% and include as many pools as possible that are <1% in "known other".

Likely 2/3rds or more of that "unknown" is known but not documented.

I've been cross-referencing digbtc.com with blockchain.info to figure out what the "Unknown IP's" are.

Slush is completely absent from the chart.  That's the majority of the Unknown [Slush + Solo Miners].
