block_target table

The targets of blocks

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.
