Custom domain - or link white-labeling - requires the Business or Enterprise Plans
Custom domain involves white-labeling Adzerk links so your domain, not Adzerk's, appears in the URL.
To enable, contact your account manager.
By default your Adzerk account will use the following URLs:
- Ad requests:
- Creative/image hosting:
With the Custom Domain extension, however, you can use your own URLs for ad serving.

Note: Keep in mind it can take up to 24 hours for the info in step #2 to propagate on your end.
It's also possible to CNAME the static subdomain, although we do not recommend this. Instead, Adzerk provides a proprietary URL for custom creative/image hosting. Contact your account manager or Adzerk support for more details.
Security recommendation: Once you have forwarded your subdomain to e-<networkId>.adzerk.net, contact Adzerk support to begin the CNAMEing process for an SSL domain. We will provide the SSL cert for you
