Let's assume there is a web server, and a host name.
If someone wants to visit the web server, the browser will first send a DNS query for this host name.
If I hope all DNS query for this web server should be notified to the web server immediately(so the web server knows which IP did the query), is it possible or not?
for example, all DNS queries will be forwarded by DNS server to the web server host, and the DNS server on the host respond to the web browser directly. how about the delay?
or DNS server sends a notification packet to the web server immediately when it receives a DNS query for the web server. how about the delay?
