• Key Concepts: 
  A wildcard DNS record is a type of Domain Name System (DNS) record that allows a single DNS entry to match multiple hostnames. It is used to route all requests for non-existent subdomains to a single server. In the context of SAP Cloud Foundry, it is used to route requests for non-existent subdomains to the Cloud Foundry router. 
  
  How to use it: 
  To use a wildcard DNS record in SAP Cloud Foundry, you must first create a DNS entry for the domain you wish to use. This entry should include an asterisk (*) as the subdomain, which will act as the wildcard. Once this is done, you can configure the Cloud Foundry router to route requests for non-existent subdomains to the router. 
  
  Tips & Tricks: 
  When configuring a wildcard DNS record in SAP Cloud Foundry, make sure that the asterisk (*) is placed at the beginning of the subdomain. This will ensure that all requests for non-existent subdomains are routed to the router.
