DNS Lookup Find DNS records

DNS is one of those essential technologies that we take for granted. It’s what allows your computer to access websites by translating their names into numerical addresses. But DNS lookup can be used for much more than just looking up web addresses. DNS records can be used to track down any type of information, from domain names to IP addresses. In this blog post, we will show you how DNS lookup works and how you can use it to track down the information you need.

What is DNS?

Domain Name System (DNS) is a hierarchical naming system for computers and other devices on the Internet. It enables a device to look up its name in a database of names servers, which are arranged in hierarchies. This database of DNS servers is often abbreviated as "DNS".

The DNS protocol was initially designed by Dan Lynch at Xerox PARC in the early 1980s. One of the goals of DNS was to provide a universal naming system for the Internet. The design of DNS was later subsumed into the Domain Name System Protocol Specification, which is published by IANA.

A DNS server responds to requests for domain names with corresponding A records or CNAME records. An A record tells the client what type of resource (host or service) is located at that particular IP address. For example, if you type www.google.com into your web browser, your computer will query a DNS server for the IP address for google.com and use that information to lookup the appropriate A record in order to resolve the hostname to an actual port number on Google's website (e.g., 80). Similarly, when you type localhost into your web browser, your computer queries a local DNS server for localhost and uses that information to look up an A record containing the address 127.0c0f8 (the loopback interface on your computer). If there is no such record present, your computer queries another local DNS server specified in /etc/

What are the benefits of DNS?

DNS lookup can be used to find DNS records for a given domain name. This can be useful for retrieving information such as the IP address, hostname, and other contact details for a domain name. Additionally, DNS lookup can also be used to locate the A, MX, CNAME, and NS records for a given domain name.

How to lookup a DNS record

To look up a DNS record, use the nslookup command on a computer that is connected to the Internet. Type the following command in a terminal window:

nslookup example.com

You should see an output that looks something like this:

> nslookup example.com Server: 10.10.10.1 Address: 10.10.10.1#53 Non-authoritative answer: > name server A Records for name server A are listed below. > address 10.10.10.1 3600 IN A 10.0.0 255.255.255.0 > address 10.10.20.1 3600 IN A 10.0.0 255.255.255

Conclusion

DNS lookup can be a helpful tool when troubleshooting problems with your internet connection. By using DNS records, you can map an IP address to the name of the website or service that it belongs to. This can be especially useful if you're having trouble logging in to a website, or if you're having intermittent connectivity issues.
