Fields
bt_id
Primary key.
bt_address
Blocked IP address or range in dotted-quad form, or null for a user block. If bt_auto is 1 then the address is private.
bt_user
Blocked user ID or null for IP blocks.
bt_user_text
The name of the blocked user, or null for IP blocks. For Special:BlockList sorting. (T48013)
bt_auto
Indicates that the IP address was banned because a banned user accessed a page through it. If this is 1, ipb_address will be hidden, and the block identified by block ID number.
bt_range_start
Start of an address range, in hexadecimal. Null for single-IP and user blocks.
bt_range_end
End of an address range, in hexadecimal. Null for single-IP and user blocks.
bt_ip_hex
If the block is for a single IP, this is the IP address in hexadecimal. If the block is for a range, the start of the range in hexadecimal, identical to bt_range_start.
bt_count
The number of block rows associated with this target.
