The client sends the DNS query to the local (recursive) DNS server.(C) Local DNS Server Check Cache
The local DNS server first checks its cache to see if the answer is already available.(D) Query root DNS Server
If not cached, the local DNS server queries the root DNS server.(E) Query TLD DNS Server
