What is DNS lookup?
A DNS lookup queries the Domain Name System to find records for a domain. These records tell the internet where your website, email, or other services are located.

A DNS lookup queries the Domain Name System to find records for a domain. These records tell the internet where your website, email, or other services are located.
An A record maps a domain name to an IPv4 address (like 93.184.216.34).
If a site is not loading, checking the A record is often the first step.
An AAAA record maps a domain to an IPv6 address. It’s the IPv6 version of an A record and is increasingly common.
MX records define which mail servers receive email for a domain. If email isn’t arriving, MX records (and related SPF/DKIM in TXT) are the usual suspects.
TXT records store text data such as SPF, DKIM, and verification tokens. Many services ask you to add a TXT record to prove domain ownership.
NS records specify the authoritative nameservers for a domain. If NS records point to the wrong provider, other record changes won’t take effect correctly.
The SOA record includes administrative information for a DNS zone (like the primary nameserver and timing values). It’s useful when debugging zone configuration and refresh behaviour.
DNS servers translate domain names into IP addresses, making them a critical part of how the internet functions. Because of this, DNS infrastructure is often scanned or targeted during reconnaissance and large-scale cyber attacks. Monitoring DNS records and domain configurations can help detect misconfigurations or suspicious activity.
A PTR record maps an IP address back to a hostname. A reverse DNS lookup queries that record, unlike a regular DNS lookup that finds IP addresses or other records for a domain.
When you enter a website address in your browser, the domain name must first be translated into an IP address. This process is handled by the Domain Name System (DNS). A DNS lookup shows the IP address and related records for a domain. The resulting A and AAAA records identify the domain's IPv4 and IPv6 addresses.
