Reverse DNS allows a user to identify the domain that is associated with an IP address. Users have the ability to update their Reverse DNS records at any time to change the PTR and time to live (TTL). Within the Manage version Customer Portal, updates to PTR records may be made in bulk using the Search and Replace tool. This tool allows a user to enter a portion of a PTR or the full PTR in the Search field and replace each occurrence within corresponding PTRs with the desired information. Please note, this tool only works when existing PTRs are associated with the Server or VLAN. If no PTRs exist, there will be no details listed and attempts to update will result in an error. To add a Reverse DNS PTR record, refer to Add and Edit a PTR (Pointer) Record. Follow the steps below to update a Reverse DNS record.
