What is DNS Lookup?

DNS (Domain Name System) translates domain names to IP addresses. A DNS lookup reveals the records associated with a domain: A records (IPv4), AAAA records (IPv6), MX records (mail servers), NS records (nameservers), TXT records (verification, SPF, DKIM), and CNAME records (aliases).
