Local Query (DNS Cache)
Your device checks its local DNS cache to see if it already knows the domain's IP.
Recursive DNS Server
If not in cache, the query is sent to the configured recursive DNS server.
Root Servers
The recursive server queries the 13 global Root Server clusters.
TLD Servers
Root Servers redirect to Top Level Domain servers (.com, .es, .org).
Authoritative Server
The specific domain's authoritative DNS server is queried.
Response and Cache
The response is returned and each server caches info according to TTL.
