Setting a custom domain makes your website available on a domain name that you control, such as
my.mobiledsp.com, rather than Avazu Mobile DSP domain
1. Update your DNS
Update your DNS to redirect your chosen aliased URL (e.g.:
mdsp.avazutracking.net using a CNAME record.
Each registrar has its own method of adding CNAME records.
It may take several hours for your DNS changes to take effect.

2. Set your CNAME in Avazu Mobile DSP
