If one adds a Wildcard subdomain entry in the DNS Zone, for example:
*.example.com. 3600 IN A <Some IP>
How much of a query for say
somerandomsubdomain.example.com be cached?
After some research I did find out that
example.com will be cached at various points and thus my DNS server can directly query
example.com DNS server for the subsequent
But do Servers/routers/OS while caching also cache that
*.example.com is a wildcard entry and hence all future queries for other random subdomains of
example.com be resolved immediately?
