domain lookup

When operating in the vast world of the internet, occasionally you need to gather information about a domain name. The whois protocol becomes crucial in such cases, providing administrative info about domains, including the owner, registrar, and contact information, depending on privacy settings. In this blog post, we’ll explore how to install and use the whois tool on various Linux distributions, such as Ubuntu, Fedora, and openSUSE. Whois is a widely used Internet record listing that identifies who owns a domain and how to get in contact with them directly. The Internet Corporation for Assigned Names and Numbers (ICANN) regulates domain name registration and ownership.

DNS, or Domain Name System, is a fundamental part of the internet's infrastructure, quietly translating human-friendly domain names into machine-friendly IP addresses that computers use to identify each other on the network. For anyone delving into network administration, IT support, or just keen on understanding how the internet works, DNS lookups are an essential skill. Today, we’ll explore two primary tools used for DNS troubleshooting and analysis: nslookup and dig. Before we dive into the tools, let's briefly discuss what happens during a DNS lookup. When you type a website like example.com into your browser, your computer performs a DNS lookup to find the corresponding IP address.
