DNS LOOKUP
Perform comprehensive DNS lookups to retrieve DNS records for any domain. This tool provides detailed information about a domain's DNS configuration including A, AAAA, MX, NS, TXT, SOA, and CNAME records.
WHAT IS DNS?
DNS (Domain Name System) translates human-readable domain names into IP addresses that computers use to identify each other on the network.
ABOUT DNS RECORDS
DNS (Domain Name System) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. Here's what the different DNS record types mean:
A RECORD
Maps a domain name to an IPv4 address. This is the most basic DNS record type and is used to point a domain to a web server.
AAAA RECORD
Similar to an A record, but maps a domain name to an IPv6 address instead of IPv4.
MX RECORD
Mail Exchange records specify the mail servers responsible for accepting email on behalf of a domain and their priority.
NS RECORD
Name Server records delegate a DNS zone to use the given authoritative name servers. These are critical for DNS resolution.
TXT RECORD
Text records store text information. They're often used for SPF, DKIM, and DMARC records for email authentication.
SOA RECORD
Start of Authority records contain administrative information about the DNS zone, including the primary name server and TTL values.
CNAME RECORD
Canonical Name records are aliases that point one domain name to another. They're often used for subdomains like www.
WHOIS
Not a DNS record, but a protocol that provides information about domain registration, including owner, registrar, and important dates.
COMMON USES
- Troubleshooting email delivery issues
- Verifying domain ownership
- Setting up website hosting
- Configuring email security (SPF, DKIM, DMARC)
- Investigating suspicious domains
- Domain reconnaissance for security assessments
