Dynamic DNS will not allow Route 53 wildcard record
When configuring a dynamic DNS client to update Route 53 (AWS) records, the web form will not validate a hostname that contains a wildcard character, e.g.: "*.example.com". Creating A-records with wildcard characters is allowed in Route 53.
Additionally, creating a dynamic DNS client for "example.com" and enabling the "wildcards" option will not update the record with a literal wildcard, in this case, "*.example.com"
The expected behavior is that a hostname with a wildcard character would be allowed, given that it's a perfectly valid DNS record in Route 53.
