Help! I Can't Refer a DNS Record to a Foreign Domain


When creating a DNS record of certain types (most commonly MX, CNAME), it is very common to refer to a foreign host in another domain.
In that case, the “trailing dot” plays an important role in defining the record correctly, as in this example.

Incorrect for pointing to foreign domain: Missing the trailing dot; Peplink would append the domain name to the record.

Correct: Trailing dot is there; Peplink knows that the desired host name terminates here.
