Understanding What a Host Name Is
A host name is a human-readable label assigned to a device on a network. It allows users and systems to identify and access devices without remembering complex numerical IP addresses.
This name plays a critical role in networking, especially when dealing with multiple devices.
Host names usually follow certain conventions and can provide information about the device’s function or location within a network. For example, a server might be named server01, while a workstation could be called workstation23.
This naming helps organize devices logically.
Besides internal networks, host names are commonly used on the internet as part of domain names, like www.example.com. The system translates these names into IP addresses through the Domain Name System (DNS), making communication seamless.
“A host name is the cornerstone of network identity, providing clarity amid countless devices.”
Key Characteristics of Host Names
- Unique within a local network to avoid conflicts
- Often limited to alphanumeric characters and hyphens
- Can be descriptive to indicate device roles
- Used alongside IP addresses for device identification

“Command-line tools offer fast, reliable access to system details like host names.”
Checking Host Name on macOS
Apple’s macOS offers multiple ways to find your host name, catering to both users who prefer graphical interfaces and those comfortable with terminal commands.
Since macOS is based on Unix, many terminal commands used in Linux also apply here. Additionally, system preferences provide an easy-to-navigate option for non-technical users.
Understanding how to access your host name on macOS is handy, especially when setting up remote connections or sharing files within a network.
Using Terminal
Open the Terminal app and type:
hostname
This command will print your current host name.
Through System Preferences
Go to System Preferences > Sharing. At the top, you will see the Computer Name, which acts as the host name.
Advanced Terminal Commands
For more detailed information, you can use:
- scutil –get HostName – Shows the host name
- scutil –get LocalHostName – Displays the local host name used by Bonjour
- scutil –get ComputerName – Retrieves the user-friendly device name
| Command | Purpose |
| hostname | Displays the current host name |
| scutil –get HostName | Shows the system-defined host name |
| scutil –get LocalHostName | Shows local Bonjour name |
| scutil –get ComputerName | Displays the user-friendly computer name |
Discovering Host Name on Linux
Linux systems provide powerful command-line tools to reveal the host name quickly. Since Linux is widely used in server environments, knowing these commands is valuable for administrators and developers.
Most Linux distributions use similar commands, and some graphical environments offer settings panels for user convenience. However, the terminal remains the most reliable method.
Checking the host name helps when configuring services, connecting remotely, or managing multiple servers efficiently.
Using the hostname Command
Simply open a terminal and type:
hostname
This prints the current host name.
Viewing /etc/hostname File
The host name is stored in the /etc/hostname file. You can view it by typing:
cat /etc/hostname
This file contains the persistent host name used during system startup.
Using hostnamectl Utility
The hostnamectl command provides detailed information and allows changing the host name:
hostnamectl status
This shows the static, transient, and pretty host names.
“In Linux, the host name is a key identifier that often corresponds to server roles or locations.”
Checking Host Name on Mobile Devices
Mobile devices like smartphones and tablets also have host names, though they are less obvious. Knowing how to find them can be useful when connecting devices to networks or troubleshooting Wi-Fi issues.
Both Android and iOS provide ways to check the device name, which typically acts as the host name on local networks.
While mobile devices don’t offer command line access like desktops, the settings menus are intuitive and user-friendly.
Finding Host Name on Android
Go to Settings > About phone > Device name. This name is used as the host name when connecting to networks.
Finding Host Name on iOS
Navigate to Settings > General > About > Name. This device name is visible to other devices on the same network.
