Introduction:
Have you ever wondered what your server name and address are? These crucial pieces of information are essential when it comes to connecting to your server and ensuring its smooth operation. In this comprehensive guide, we'll delve into everything you need to know about your server's name and address, diving into the specifics of different operating systems and configurations.
What's My Server Name?
Subheading: Finding Your Server Name in Windows
Steps:
- Open System Properties: Right-click on "This PC" and select "Properties."
- Check Computer Name: On the "System" tab, you'll find your server's name under "Computer name."
Subheading: Discovering Your Server Name in Linux
Steps:
- Use Hostname Command: Open a terminal window and type "hostname." This will display your server's hostname.
- Check /etc/hostname: Navigate to "/etc/hostname" using a text editor and open the file. Your server's hostname will be the only text within this file.
What's My Server Address?
Subheading: Identifying Your IPv4 Address
Your server's IPv4 address is a unique numerical address that identifies it on a network.
Steps for IPv4:
- Use ipconfig Command (Windows): In a command prompt, type "ipconfig /all." Look for "IPv4 Address" under your network adapter.
- Use ifconfig Command (Linux): In a terminal, type "ifconfig." Your server's IP address will be listed under "inet addr."
Subheading: Determining Your IPv6 Address
IPv6 is the newer version of IP addressing, designed to replace IPv4.
Steps for IPv6:
- Use ipconfig Command (Windows): In the same "ipconfig /all" output, look for "IPv6 Address."
- Use ifconfig Command (Linux): Type "ifconfig" in a terminal. Find your server's IPv6 address under "inet6 addr."
Common Server Name and Address Issues
