Error “A DNS entry already exists” – what does it mean and how do I fix it?

This error appears when you try to add a DNS record (of type A, CNAME, MX, etc.) for a name that already has a record of the same type in the domain's DNS zone.

DNS generally doesn't allow two identical records (same type and name) for the same host (there are exceptions, e.g. multiple MX records with different priorities, or multiple A records for round-robin).

To fix it:

1. check the domain's DNS zone (from your EUReg customer account, if you use EUReg's nameservers) for an existing record with the same name and type;
2. edit or delete the existing record instead of adding a new one, or
3. if you want that name to point somewhere else, update the value (the IP or destination) of the existing record instead of creating a new one.
