DNS Lookup




DNS Information Lookup

Use this tool to retrieve detailed DNS information about a domain name.

What is DNS Lookup?

DNS (Domain Name System) lookup is the process of querying DNS servers to retrieve DNS records associated with a domain name. These records provide essential information about a domain’s configuration, including its IP addresses, name servers, mail servers, and more.

Understanding DNS Records

Here’s a detailed explanation of commonly used DNS record types:

  • A (Address) Record: Maps a domain name to an IPv4 address. It’s used to point a domain to a specific IP address. Expect to see the IPv4 addresses associated with the domain.
  • AAAA (IPv6 Address) Record: Similar to the A record but maps a domain name to an IPv6 address, which is used for IPv6 connectivity. Expect to see the IPv6 addresses associated with the domain.
  • CNAME (Canonical Name) Record: Creates an alias for a domain name, pointing it to another domain’s canonical (true) name. It’s often used for subdomains or domain aliases. Expect to see the canonical domain names associated with the domain.
  • MX (Mail Exchange) Record: Specifies the mail server responsible for receiving email messages on behalf of a domain. It directs email traffic to the correct mail server. Expect to see the mail servers associated with the domain.
  • NS (Name Server) Record: Specifies the authoritative name servers for a domain. It identifies the DNS servers responsible for providing DNS information for the domain. Expect to see the authoritative name servers associated with the domain.
  • TXT (Text) Record: Stores arbitrary text data associated with a domain. It’s commonly used for domain verification, email sender policies, and other purposes. Expect to see any textual data associated with the domain.
  • CAA (Certification Authority Authorization) Record: Specifies which certificate authorities are allowed to issue certificates for a domain. It helps enforce certificate issuance policies. Expect to see certificate authority authorization records associated with the domain.

  • SRV (Service) Record: Specifies the location of services within a domain. It’s used for service discovery, such as locating SIP or XMPP services. Expect to see service records associated with the domain.
  • SOA (Start of Authority) Record: Provides authoritative information about a DNS zone, including the primary name server, the email address of the domain administrator, and various timing parameters. Expect to see start of authority records associated with the domain.
  • HINFO (Host Information) Record: Provides information about the type of hardware and operating system used by the domain’s host. Expect to see host information records associated with the domain.
  • RP (Responsible Person) Record: Specifies the mailbox of the responsible person or administrative contact for the domain. Expect to see responsible person records associated with the domain.
  • PTR (Pointer) Record: Used for reverse DNS lookups to map an IP address to a domain name (reverse DNS). Expect to see pointer records associated with the domain.

After submitting a domain name, you can expect to see a table displaying the various DNS records associated with the domain. Each record type will be listed along with its corresponding values.
