--- title: Preloaded attributes description: This article describes preloaded attributes. url: https://docs.tealium.com/server-side/attributes/preloaded/ --- ## How it works For your convenience, AudienceStream and EventStream contain a set of preloaded event, visit, and visitor attributes. Each attribute is configured to collect statistical information that can help you determine useful information about each visitor or visit. These attributes do not require additional data beyond the standard event data from the [Tealium Collect tag](https://docs.tealium.com/tealium-collect-tag/).
Preloaded attributes cannot be modified, but you can duplicate them and modify the copy. The duplicate contains all of the enrichments and rules from the original.

To enable IPv6, add an AAAA DNS record that points to the same distribution as the domain's A record. **Other components** The following components do not support IPv6: * Tealium Collect tag and Collect HTTP API (`collect.tealiumiq.com` and `collect-.tealiumiq.com`) * First-party Collect domains * Tealium v1, v2, and v3 APIs (`platform.tealiumapis.com`) * Connectors and external file imports To create an attribute that uses the IPv4 address as a fallback when the IPv6 address is not available, see the [Setting Fallbacks When Using IPv6](https://support.tealiumiq.com/en/support/solutions/articles/36000521207) knowledge base article. ## Examples The following examples demonstrate how you can use preloaded attributes: * Use the **Frequent visitor** badge to create an audience, and then action that audience with a connector to send email to those visitors that says "Thank you for being a regular visitor." * Use the **Lifetime operating systems used (favorite)** attribute to change the placement of specific downloads on a page, making more relevant apps appear first. * Use **Total Direct Visits** and **Total Referred Visits** to calculate the ratio of direct to referred visits for a visitor to understand each visitor or visit.
