Did you know performing DNS lookups is essential for IT personnel, network administrators, and security specialists? In simple terms, DNS lookup is the querying of the DNS server for information about a domain name, including the IP address associated with it, mail server data, or other DNS records. Therefore, knowing the efficient methods for DNS lookups can help solve connectivity issues, identify network issues, and strengthen cybersecurity habits. A DNS lookup converts domain names to IP addresses. You perform a DNS query when you enter a URL in a browser, which returns the equivalent IP address. DNS lookups allow the user to retrieve useful information about a domain's DNS records, including the A, MX, CNAME, TXT, and many more.
