Manual:Ipblocks table

The ipblocks table stores details of IP addresses and users who are blocked from editing.

The name "ipblocks" is a legacy name, as now user account blocks are also stored in this table.

For previous blocks, see .

ipb_id
Primary key, introduced for privacy.

ipb_address
Blocked IP address in dotted-quad form or user name.

ipb_user
Blocked user ID or 0 for IP blocks.

ipb_by
User ID of the administrator who made the block.

ipb_by_text
Text username of the administrator who made the block.

ipb_reason
Reason for the block given by the administrator.

ipb_reason_id and the comment table should be used instead!

ipb_reason_id
This is a foreign key to  in the  table.

ipb_timestamp
Creation (or refresh) date in standard YMDHMS form.

ipb_auto
Indicates that the IP address was blocked because a blocked user accessed a page through it.

If this is 1, ipb_address will be hidden.

ipb_anon_only
If set to 1, the block only applies to logged out users.

ipb_create_account
Prevents account creation from matching IP addresses.

ipb_enable_autoblock
Enables autoblock on the block.

ipb_expiry
Expiry time set by the administrator at the time of the block.

A standard timestamp or the string 'infinity'.

ipb_range_start
The first IP in an IP range block.

ipb_range_end
The last IP in an IP range block.

ipb_deleted
Allows the entry to be flagged, hiding it from users and sysops.

ipb_block_email
Prevents the user from accessing <tvar|1>Special:Emailuser</>.

ipb_allow_usertalk
Indicates whether the blocked user is blocked from editing their talk page.

A value of 1 means that the user is allowed to edit their user talk page.

ipb_parent_block_id
ID of the block that caused this block to exist.

Autoblocks set this to the original block so that the original block being deleted also deletes the autoblocks.

ipb_sitewide
Indicates whether the block is sitewide or partial. A value of 0 indicates that the block is partial. A partial block can block a user from specific pages, namespaces or actions. If a partial block blocks a user from any pages or namespaces, these are stored in the ipblocks_restrictions table.
