What is a DNS Lookup?

A DNS lookup is the process of finding information associated with domain names. Most commonly, it involves translating a domain name into an IP address. However, DNS lookups can retrieve various types of records stored in the DNS.

Common DNS Record Types

A Record

Maps a domain name to an IPv4 address. This is the most common type of DNS record and is used to find the IP address of a computer connected to the internet.

Example: example.com. 3600 IN A 192.0.2.1

AAAA Record

Maps a domain name to an IPv6 address. Similar to an A record but for the newer IPv6 address format.

Example: example.com. 3600 IN AAAA 2001:db8::1

CNAME Record

Creates an alias from one domain to another. The CNAME record is used to map a subdomain to another domain.

Example: www.example.com. 3600 IN CNAME example.com.

MX Record

Specifies the mail servers responsible for accepting email on behalf of a domain and their priority.

Example: example.com. 3600 IN MX 10 mail.example.com.

NS Record

Delegates a DNS zone to use the given authoritative name servers. These records identify the DNS servers responsible for a zone.

Example: example.com. 3600 IN NS ns1.example.com.

TXT Record

Contains text information for sources outside your domain. Often used for domain verification, SPF, DKIM, and DMARC records.

Example: example.com. 3600 IN TXT "v=spf1 include:_spf.example.com ~all"

How to Use the DNS Lookup Tool

  1. Enter the domain name you want to look up (e.g., example.com)
  2. Select the DNS record type you're interested in
  3. Click the "Lookup DNS" button
  4. View the results showing all matching records

Understanding DNS Lookup Results

DNS lookup results typically include the following information:

  • Name: The domain name the record belongs to
  • TTL (Time To Live): How long the record can be cached before it should be refreshed
  • Class: Almost always "IN" for Internet
  • Type: The record type (A, AAAA, MX, etc.)
  • Data: The actual data for the record, which varies by record type
