Manage CNAME records in Domain.com

This document will guide you through the steps to create, modify and delete the CNAME record(s) necessary for implementing OneTag 2.0 in the Domain.com hosting platform.

Overview

OneTag 2.0 is Criteo’s latest cross-device innovation protecting your reach of shoppers as well as facilitating ad relevance and ensuring accurate sales attribution.

To implement OneTag 2.0 it is necessary that you delegate Criteo a sub-domain by creating a CNAME record in your name-server/hosting platform. In a Domain Name System (DNS) context, a Canonical Name (often abbreviated CNAME) record is a name-server resource record that maps one domain name (an alias) to another domain name (the Canonical name) section 3.3.1 of RFC 1035.

Sub-domain delegation

Please create the following CNAME record(s) on your Domain.com hosting platform:
