Reverse Records

Reverse records are commonly set mainly for mail servers, as they are used to verify the identity of the sending server. 

The recipient of the email usually performs the following check:

1. They find the reverse record for your server's IP address (for example, they resolve 46.28.106.11 to  wes1-mx1.wedos.net).
2. They resolve the found name back to an IP address again – that is, the A record for the relevant domain (wes1-mx1.wedos.net to 46.28.106.11).
3. They compare the results of the lookups. If the server IP address and the DNS record match, the email usually gets through; otherwise, the recipient's server may reject it.

With this procedure, the recipient verifies that the name in the reverse record has not been spoofed. In theory, you can enter any domain name into a reverse record even if you have nothing to do with it. However, only the owner of that domain can set the reverse lookup of that name to an IP address.

Setting Up Reverse Records

Set reverse records for server and cloud services by following these steps:

1. Log in to the customer administration ⧉.
2. In the top menu, select Server Services or Cloud.
3. Select the service for which you want to set reverse records.
4. In the left menu, select IPv4 Reverse Records or IPv6 Reverse Records.
5. Select the address and enter the corresponding record data (complete domain or subdomain).
6. Confirm with the Insert button.

For IPv6, append the last part of the required IP address and enter the record value.

You can gradually add multiple records for one IP address.

If you need to edit or delete a reverse record, use the magnifying glass or cross buttons in the reverse records overview.
