FAQs and Tips for Domain-dns.com

This is either a simple or a complex question depending on the circumstances.

Let's handle the simple scenario first. The logical answer to the question is "Have you tried to add your domain(s)?". If you try to add a domain and get an error "zone already exists" error, then we need to look at the complex scenario.

Changes to DNS records are published every 20 minutes. Existing DNS records have a 20 minute "time to live" value, which is how long ISP DNS servers are supposed to cache them for. This means a change to an existing IP address could take up to 40 minutes to show up. Any new records will be published in 20 minutes, but ISPs may cache "no such name" for longer than 20 minutes (so the delay could be more than 40 minutes).

Changes to Mail Forwarding are published on the same 20 minute schedule. If you enable mail forwarding and test it before the change has taken effect you will get a "relaying denied" bounce. For normal parked or otherwise default domains, mail forwarding should not take longer than 20 minutes to turn on. Domains with MX records configured may need to wait for the MX record to timeout, so they may take up to 40 minutes for mail forwarding to work.
