This type of landing page is where we direct traffic for:
Lame Delegations
A lame delegation is a domain that is not in any ZoneEdit account yet it is still delegated to ZoneEdit name servers. This generates additional queries to our name servers, especially if we have no valid data on hand for these domains, so we wildcard the traffic to a landing page.
Account Overdue
An account overdue domain has been deactivated for one of the following reasons:
Zombie Domains
A zombie domain is a domain that is still on the ZoneEdit system but for some reason has no valid DNS data associated with it. This can be caused, for example, by a domain on the system as a secondary DNS domain with an unreachable, unresponsive or misconfigured primary master. If your domain is on the system as secondary DNS make sure you are using the correct secondary ACL in your primary master configuration.
Deactivated Domains
A deactivated domain has been deactivated by the user but it is still delegated to ZoneEdit name servers (same as lame delegation above).
