Domain Name System (DNS) is a hierarchical and decentralised naming system for computers, like the Internet's phonebook. It includes various information with domain names assigned to each participating entity. When you try to access information online through domain names, like "whoisnote.com", internet browsers interact through Internet Protocol (IP) addresses. DNS interprets such domain names to IP addresses so browsers can gather Internet resources.

With the WHOISnote DNS checker tool, visitors can quickly get their DNS Lookup service. The DNS search is done directly against the domain's authoritative name server, so DNS Records should appear instantly.

Features of WHOISnote DNS Check

  • All DNS Records show in a single search.
  • DNS records are displayed separately, so there is no single missing record
  • Search domains logging system
  • Search engine optimised
  • Sitemap of the recently searched domain (sitemap link)
  • Search form customisation (you can edit button text, placeholder, etc.)

Frequently Asked Questions (FAQ)

1. How does DNS work?

Every IP address has been assigned to each device on the Internet uniquely, and that address always finds the connected device - like your home street address is used to see you. When t a user types into their web browser (example.com), the device translates it into the machine-friendly address (DNS) to locate the example.com webpage.
The DNS process involves converting a hostname (www.example.com) into a computer-friendly IP address (i.e. The process behind the DNS resolution is the different hardware components, so a DNS query must pass. The DNS lookup happened "behind the scenes" and requires no interaction from the user's computer apart from the initial request.

2. What types of DNS records can I search for?

You can search for various types of DNS records, including:

  • A (Address) records: Maps a domain name to an IPv4 address.
  • AAAA (IPv6 Address) records: Maps a domain name to an IPv6 address.
  • CNAME (Canonical Name) records: Provides an alias for a domain.
  • MX (Mail Exchange) records: Specifies the mail servers responsible for receiving email for a domain.
  • TXT (Text) records: Contains arbitrary text and is often used for various purposes, such as SPF records for email authentication.
  • NS (Name Server) records: Specifies the authoritative name servers for a domain.

3. How can I perform a DNS search?

You can perform a DNS search using various methods, including:

  • Online DNS lookup tools or websites.
  • Command-line tools like "nslookup" or "dig."
  • Through your operating system's network settings.
  • Using DNS query tools provided by domain registrars or hosting providers.

4. What information does a DNS search reveal?

A DNS search typically reveals the IP address associated with the domain name you're querying, along with any other relevant DNS records for that domain.

5. Can I check the DNS history of a domain using a DNS search?

No, a standard DNS search does not provide historical data about changes in DNS records. To track DNS record changes over time, you may need to use specialized DNS monitoring or historical DNS data services.

6. Can I use DNS search to troubleshoot internet connectivity issues?

Yes, DNS search tools can help diagnose and resolve internet connectivity issues. You can check if a domain's DNS records are resolving correctly, which can be useful in identifying problems like DNS server issues or misconfigured records.

7. Are there public DNS servers I can use for DNS searches?

Yes, there are public DNS servers provided by organizations like Google ( and and Cloudflare ( that you can use for DNS queries. These servers are often faster and more secure than default DNS servers provided by your internet service provider.

8. Can DNS search tools help with domain security?

DNS search tools can assist in monitoring and securing your domain by allowing you to check DNS records for issues like incorrect or unauthorized changes. They can also help detect DNS-related threats, such as DNS hijacking.

9. How often should I perform DNS searches for my domains?

Regular DNS checks are advisable, especially after making DNS changes or experiencing connectivity issues. Monitoring your DNS records periodically can help ensure the correct functioning of your online services.

Remember that DNS is a fundamental part of internet infrastructure, and understanding how to use DNS search tools can be valuable for both troubleshooting and managing your online presence.
