Complete the code to identify the first step in DNS resolution.
When a user types a URL, the browser first sends a request to the [1] to find the IP address.The local DNS resolver is the first point of contact that the browser queries to resolve a domain name into an IP address.
Complete the code to show which server the local resolver queries if it has no cached record.
If the local DNS resolver does not have the IP cached, it queries the [1] to continue the resolution process.
The local resolver queries the root DNS server to find the next step in the domain name resolution hierarchy.
Fix the error in the DNS resolution step where the resolver queries the wrong server.
After contacting the root DNS server, the resolver should query the [1] to find the domain's IP address.
The resolver queries the authoritative DNS server for the domain to get the exact IP address.
Fill both blanks to complete the DNS resolution flow from root to domain.
The root DNS server directs the resolver to the [1] which then points to the [2] for the domain's IP.
The root server points to the TLD server, which then directs to the authoritative DNS server that holds the domain's IP.
Fill all three blanks to complete the DNS caching and resolution process.
Once the authoritative DNS server returns the IP, the [1] caches it, the [2] uses it to connect, and the [3] displays the website.
The local DNS resolver caches the IP for faster future queries, the client browser uses the IP to connect, and the web server displays the website content.
