Notes: This is a website registry table from CNZZ analytics platform. Column [0] 'id' is an internal auto-generated record ID (skip). Column [1] 'domain' contains tracked website URLs (skip — these are not personal PII, they are registered domains/business assets). Column [2] 'owner_id' is a numeric foreign key reference to account owners (skip — internal ID). The breach context mentions account credentials (usernames, passwords, emails) exist in a separate owners table, but this sample contains only the domain registry with no personal information. No PII columns are present in this data segment.
