Advanced Remote Access Options
Dyn Remote Access gives you the flexibility to set up your new hostname for mail routing. You also have the ability to select a custom TTL (Time To Live) value for your hostname, in the event that your use case requires it.
TTL Value
A record’s TTL, or Time To Live, is the length of time (in seconds) that caching name servers will store your host’s information in their local cache before performing a new query. Setting a low TTL value (e.g., 60 seconds) will shorten the length of time that it takes other name servers to notice that a change occurred.
Mail Routing
If your use case requires the ability to receive mail on behalf of the hostname you’ve created, you can use this field to specify the name of the mail server.
