I need to write a zone file for a new company domain. Let's say the company owns company.com and I need to write a zone file for 2 domains play1.playground.company.com and play2.playground.company.com . When defining the zone file Origin line, do I need to put in the whole FQDN play1.playground.company.com. or just play1.playground is enough? Will the following zone file work out?
$ORIGIN play1.playground.company.com.
$TTL 3600
