QUESTION: What does the @ symbol
mean with respect to DNS?
ANSWER:
The @ SYMBOL in this context is used as a pointer. The zone will
look to the next @ to see where the origin or main domain resolves to
for this zone file. This symbol is used as a standard world wide for this
type of zone file entry. Any record using the @ symbol will resolve to
the same IP address that the main domain resolves to.
