How to Find a Server’s URL

Method 1: You Know the Service or Website

Is it a Standard Website? If you’re looking for a regular website, the server’s URL is the domain name itself (e.g., www.google.com).

Specific Service on a Website? Many websites host multiple services with subdomains. For example, the image hosting part of Imgur is i.imgur.com , separate from the main www.imgur.com. You can identify these subservices through navigation menus or the way the URL changes as you use the site.

Method 2: From Within the Network

If you’re on the same network as the server, you can use these tools:

ping Command:

Open a command prompt (Windows) or terminal (Mac/Linux).

Type ping servername (replace servername with the server’s computer name or its known IP address).

The ping response shows the server’s URL in parentheses.

nslookup Command:

Similar to the above: nslookup servername

This command primarily returns the server’s IP address but can also reveal associated domain names.

Network Router Settings: Your router’s configuration page usually lists devices on your network. Look for the server’s name or IP address and see if any associated domain names are listed.

Method 3: External Lookup (If You Have the IP Address)

Reverse IP Lookup Tools: Multiple websites offer reverse IP lookup services.

These tools will only work for public-facing servers with associated domains and don’t always show the primary URL in use.

Important Things

Internal vs. External URLs: Servers may have an internal URL (for the local network) and an external URL (reachable over the internet). Your method depends on which one you need.

Hidden Servers: Some servers intentionally don’t have associated domain names or publicly visible IP addresses. Finding them requires network-specific knowledge.
