Explanation The dig +trace command can be used to resolve DNS requests by tracing the path from the root name servers to the authoritative name servers. This can help identify any issues with DNS resolution or delegation. The nslookup command can also be used to query DNS records, but it does not provide the trace option. The curl command can be used to transfer data from or to a server, but it does not resolve DNS requests. The ping command can be used to test the connectivity and latency between two hosts, but it does not resolve DNS requests.
