1

Local Query (DNS Cache)

Your device checks its local DNS cache to see if it already knows the domain's IP.

2

Recursive DNS Server

If not in cache, the query is sent to the configured recursive DNS server.

3

Root Servers

The recursive server queries the 13 global Root Server clusters.

4

TLD Servers

Root Servers redirect to Top Level Domain servers (.com, .es, .org).

5

Authoritative Server

The specific domain's authoritative DNS server is queried.

6

Response and Cache

The response is returned and each server caches info according to TTL.
