What is a DNS Lookup Tool?

A DNS Lookup Tool is an essential utility that allows you to query and retrieve Domain Name System (DNS) records for any domain name. DNS acts as the internet's phonebook, translating human-readable domain names into IP addresses that computers use to identify each other on the network.

Understanding DNS Record Types

• A Record: Maps a domain to an IPv4 address
• AAAA Record: Maps a domain to an IPv6 address
• MX Record: Specifies mail servers for the domain
• CNAME Record: Creates an alias from one domain to another
• TXT Record: Stores text information, often used for verification and SPF records
• NS Record: Specifies authoritative name servers for the domain
• SOA Record: Contains administrative information about the DNS zone
• SRV Record: Specifies location of services
• PTR Record: Used for reverse DNS lookups
• CAA Record: Specifies which certificate authorities can issue SSL certificates
