`DBSubnetGroupName` is specified.

If `DBSubnetGroupName` isn't specified, and `PubliclyAccessible`
isn't specified, the following applies:

* If the default VPC in the target region doesn’t have an Internet
  gateway attached to it, the DB instance is private.

* If the default VPC in the target region has an Internet gateway
  attached to it, the DB instance is public.

If `DBSubnetGroupName` is specified, and `PubliclyAccessible` isn't
specified, the following applies:

* If the subnets are part of a VPC that doesn’t have an Internet
  gateway attached to it, the DB instance is private.

* If the subnets are part of a VPC that has an Internet gateway
  attached to it, the DB instance is public.
