DNS Lookup - Find All DNS Records Configured for Any Domain

DNS lookup tool offers online lookup for all DNS records configured for a domain.  Find out the A, AAAA, CNAME and other common DNS records for your domain and many more.

How to perform the DNS lookup to find all DNS records configured for any domain?

The process of looking up DNS records through our tool is quite simple. To perform the DNS records lookup, take the following steps.

  • Open the DNS lookup tool.

  • Enter the domain and select the DNS record you want to check.

  • If you want to perform the lookup of all the DNS records configured for the domain, select "ALL" from the dropdown list.

  • Then press the "DNS Lookup" button.

  • The tool will provide all the DNS records configured for that domain.

What is DNS?

DNS (Domain Name System) is responsible for translating human-readable domain names (such as Google.com) to IP addresses (such as 8.8.8.8) so that the websites, devices, and other online services associated with them (the domain names) can be accessed.

Just as humans use phone books to find the number of a particular person, DNS works to check the IP address of a particular domain. 

Since computers require IP addresses to communicate with one another over a network, it is necessary for domain names to be converted into their respective IP addresses using DNS.

What is a DNS record?

DNS records can be understood as pieces of instructions that are added to a DNS server pertaining to a particular domain.  There are different types of DNS records that are added to a server against a domain. These records perform various types of tasks, such as defining the IP address of the domain, or defining the recipient email server, etc.

The DNS records are added in the form of textual information. Some records only contain numerical values while others contain data in TXT format

What Are the Most Common Types of DNS Records Supported by Our Tool?

The following are the most common DNS records used to resolve host names into IP addresses:

  • A record: This record holds the IPv4 address for a domain.

  • AAAA record: This record contains the IPv6 address for a domain.

  • CNAME record: This record does not provide an IP address. That is used to alias a hostname to another hostname. In simple words, CNAME forwards one domain or subdomain to another domain.

  • MX record: It directs incoming mail to a mail server. MX record specifies the SMTP mail servers for that domain.

  • NS record: This record contains the nameserver's information for the domain. It sets the authoritative nameservers and provides the addresses for those nameservers.

  • PTR record: This record directs the IP address to a hostname. PTR record is used to perform the reverse IP lookup. Just like an A or AAAA record provides the IP address for a domain, the PTR record provides the domain for an IP address.

  • SRV record: This record specifies the port for specific services. It's like MX but for other communication protocols, such as messaging, VoIP, etc.

  • SOA record: This record stores the admin information about a domain, such as contact details for the domain's administrator and domain serial number. It also contains information on how frequently DNS should refresh the information for a particular zone.

  • TXT record: This record saves information in the DNS server in standard TXT form. It is used for DMARC, and for other types of verification purposes.

  • CAA record: This record is a Certification Authority Authorization record. It allows a domain owner to state which certificate authorities can issue certificates for that domain. If no CAA record exists, then anyone can issue a certificate for the domain. Subdomains also inherit these records.

  • DS record: This record is also known as the Delegation Signer record. It consists of the unique characters of your public key and its associated metadata like Key Tag, Algorithm, Digest Type, and Digest (cryptographic hash value).

  • DNSKEY record: A DNSKEY record contains a public key used to verify Domain Name System Security Extension (DNSSEC) signatures.

What Are the Use Cases of Online DNS Lookup Tool?

Domain Configuration

When a network or website admin sets up a domain, they can use a DNS lookup tool to ensure that all the records are correctly entered and configured in the DNS records. For example, they can check that:

  • The CNAME records are properly added for all domains and sub-domains that have to be directed to the main domain.

  • The PTR records are correctly configured for reverse DNS lookups.

  • The TXT records are properly added for website ownership verification, outlining DMARC policies, etc.

And so on.

By doing this check, the administrator can make sure that the domain functions properly and that visitors are able to access/use the website without any issues.

Troubleshooting and Error Detection

If a domain faces issues in DNS resolution or in proper mail delivery, etc., the administrator can perform a DNS lookup to see if there is any issue in the A records or the MX records (or any of the other ones, depending on the exact issue being faced).

Since a DNS lookup tool provides information on all the various DNS records in one place, it is very easy to see if there is something wrong with any of them.

Providing Special Website Authorization

For security purposes, some network administrators may wish to block their users from accessing certain websites on the Internet. In order to block access to those websites, the network admins have to know the IP address of the domain. A DNS Lookup tool can be used to find the IP address of the domain, regardless of whether it uses the IPv4 or IPv6 format.

FAQs

How to do a DNS lookup?

A DNS lookup can be performed easily with the help of our online DNS lookup tool. However, if the need arises, you can also use the command line interface to run the process.

What is a reverse DNS lookup?

A reverse DNS lookup is the process through which the domain name assigned to a particular IP address is discovered. Usually, the process of DNS lookup reveals the IP address for a particular domain. However, the opposite happens in a reverse DNS lookup.

Can I disable DNS on the router?

Yes, you can disable DNS in your router by visiting your router settings. Depending on the ISP that you’re using and the firmware installed in your router, the exact method to disable DNS can be different. However, there is typically an option provided to disable the DNS resolution process.
