Andre, cool tool! But I notice the prefix isn't always shown correct,
e.g. telia.se displays 193.44.172.0/15 lambdanet.de displays 80.86.170.0/19, but is located at 80.86.162.17 wrong numbers, wrong cidr...

Thanks for reporting this. There seems to be a off-by-one error under certain circumstances with the network address. We are using the LC-trie to do the lookups and it looks like we made a mistake somewhere. We're looking into it.

Ok, this problem is fixed. We had an error in the lookup server LC-trie where we didn't properly lop off all the bits of the netmask. This would happen only for certain specific bit patterns and mask combinations and it a property of how the information is compressed and stored in the LC-trie. No Firefox Extension update is required as this information is entirely server generated and the fix has been applied there.
