# Domain into IP ## Understanding Domain Names and IP Addresses ### What is a Domain Name? A **domain name** is a human-readable address used to access websites on the internet. For example, `example.com` is a domain name that users can easily remember instead of typing a long numerical IP address. ### What is an IP Address? An **IP (Internet Protocol) address** is a unique numerical label assigned to each device connected to a network. It helps in identifying and locating devices on the internet. For instance, `192.0.2.1` is an IPv4 address, while `2001:0db8:85a3::8a2e:0370:7334` is an IPv6 address. ## How a Domain Converts to an IP Address ### The Role of DNS (Domain Name System) When you enter a domain name in your browser, the **DNS** translates it into an IP address. This process involves querying DNS servers to find the correct numerical address associated with the domain. ### Steps in DNS Resolution 1. **Browser Cache Check** – The browser checks if the IP is stored locally. 2. **OS & Router Cache** – If not found, the request moves to the operating system and router. 3. **DNS Server Query** – The ISP’s DNS servers resolve the domain into an IP.
| Domain Name | IP Address | example.com | 93.184.216.34 | google.com | 172.217.16.206 | ## Why Knowing the IP of a Domain Matters ### Security and Troubleshooting Finding a domain's IP helps in **security analysis**, identifying malicious servers, and troubleshooting connectivity issues. ### Bypassing DNS Restrictions In cases where DNS is blocked, directly using the IP address can sometimes allow access to the intended website.
