+# About
+
+This submodule PTR entries to the fully qualified domain name (FQDN) selected in `name`.  The zone
+is calculcated from the IP address(es).  If the zone does not exist in Route 53, and the zone is not associated
+with the VPC in which this is executed, you will get an error such as this:
+
+```script
+Error: no matching Route53Zone found
+
+  with module.lakefront_cname_test.data.aws_route53_zone.zone,

+   2: data "aws_route53_zone" "zone" {
+```
+
+The record(s) created use a default TTL of 900.  You may change this with the `ttl` option.
+
+This also creates what we call a heritage record. This is an indication of _what_ thing created the record, and when.  It is added by
+the dynamic route53 Lambdas for EC2 instances, and within this module, it uses its own details.
