Manual:ipblocks table

Manual:Contents MediaWiki database layout 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 Manual:Logging table .

Fields edit

ipb_id edit

MediaWiki version:
1.2

Primary key, introduced for privacy.

ipb_address edit

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

ipb_user edit

Blocked user ID or 0 for IP blocks.

ipb_by edit

MediaWiki version:
1.33

User ID of the administrator who made the block.

(deprecated); Deprecated in favor of ipb_by_actor.

ipb_by_text edit

MediaWiki versions:
1.13 – 1.33

Text username of the administrator who made the block.

(deprecated in 1.31); Deprecated in favor of ipb_by_actor.

ipb_by_actor edit

MediaWiki version:
1.31
Gerrit change 380669

This is a foreign key to actor_id in the actor table.

ipb_reason edit

MediaWiki version:
1.32

Reason for the block given by the administrator.

(deprecated) ipb_reason_id and the comment table should be used instead!

ipb_reason_id edit

MediaWiki version:
1.30

This is a foreign key to comment_id in the comment table.

ipb_timestamp edit

Creation (or refresh) date in standard YMDHMS form.

ipb_auto edit

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 edit

MediaWiki version:
1.8

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

ipb_create_account edit

If set to 1, prevents account creation from matching IP addresses.

ipb_enable_autoblock edit

MediaWiki version:
1.9

If set to 1, enables autoblocks to be created from the block.

ipb_expiry edit

MediaWiki version:
1.2

Expiry time set by the administrator at the time of the block. A standard timestamp or the string 'infinity'.

ipb_range_start edit

MediaWiki version:
1.6

The first IP in an IP range block.

ipb_range_end edit

The last IP in an IP range block.

ipb_deleted edit

MediaWiki version:
1.10

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

ipb_block_email edit

MediaWiki version:
1.11

If set to 1, prevents the user from accessing Special:Emailuser.

ipb_allow_usertalk edit

MediaWiki version:
1.14

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 edit

MediaWiki version:
1.20

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 edit

MediaWiki version:
1.32

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.
