When it comes to understanding technology, one of the most important topics is IP addresses. An IP address is a unique number assigned to each device that connects to the internet and allows it to be identified on a network. If you’re using a MacBook, you may be wondering how to find your IP address. Fortunately, it’s easy!
What is an IP address?
An IP address is an essential element of the technology used to identify and locate devices connected to computer networks via the Internet Protocol. This identifier is a numerical label assigned to each device or group of devices participating in a network, and stored in their system memory. It acts as an identifier for that particular device, allowing others on a network to distinguish it from others on the same network and serve as the basis for data delivery.
Your internet service provider (ISP) assigns you with your IP address so other users and websites can find you online. That way, when you request to open a website, all data being sent to you from the website originates from this address. Your IP address also allows Google to localize your search results – important when wanting relevant results tailored just for you. However, if this concerns you, there are ways to hide your IP with a VPN (Virtual Private Network). There are plenty of trustworthy providers out there such as NordVPN that allows secure web browsing without revealing your IP address.
External and internal IP addresses
An IP address is like a digital label for a device or network. It’s necessary to locate and contact them when connected to the internet. Among IP addresses, there are two types: external (also called public) or internal (private or local).
An external IP address acts as your calling card on the internet; it lets other devices find and connect with you. When you first start using the web, your Internet Service Provider (ISP) will assign this address to you; depending on its format it can be written in either IPv4, consisting of around 8-12 digits composed of four numbers divided by dots, or in IPv6, which includes around 30 digits split among eight numbers divided by colons. An internal IP address, however, isn’t disclosed to anyone outside the home network it applies to—it’s only used within that local area so no one can track it back to you.
Where is your external IP address?
To identify your external IP address, you must be connected to a router. To do this, open a browser and type in ‘what is my IP’ in the search bar. This will display your router’s public IP address which is typically set by your internet service provider.
On the other hand, if you are directly connected to the modem then there will be no need to go through a router to find your external IP address. These services will provide the modem’s public IP address upon request. Your external IP address will usually remain unchanged unless you specifically change it on the modem settings page, however certain configurations may cause it to reset periodically when you reconnect to the network.
Where is your local internal IP address?
Your local internal IP address is the one used to communicate with other devices on the same network. This is necessary for connecting to printers and other local hardware, as well as when running file sharing services like FTP servers.
Finding your internal IP address can be done by opening System Preferences and clicking on Network. Typically the Internal IP address will be listed under either an Ethernet or Airport (Wireless) interface; though depending on your network setup, it could also exist on a virtual interface such as VPN or Point-to-Point Tunneling Protocol (PPTP). You may have more than one Interface listed, so make sure you select the correct one to view its associated Local IP address.
Easy way to check IP address using Terminal
Using Terminal is an easy way of finding your IP address on a Mac computer. All you have to do is open Terminal by hitting the keyboard shortcut ⌘ + Space, and then type in ipconfig getifaddr en0. This command will display the local IP address associated with your network connection. Each device on the network, including routers, are assigned an internal IP address that uniquely identifies it within the network – this includes computers and other devices connected to the same Wi-Fi router.
Depending on what type of internet access you use, such as whether it’s wired or wireless, the commands used may differ slightly so make sure you check what command to use specifically for your connection type. Knowing your IP address can be very useful in certain scenarios such as when setting up port forwarding or troubleshooting a network issue. Finding it using Terminal is quick and easy so there’s no need to stress out if you ever need to know it.
Why your IP address is important
Knowing your IP address is potentially beneficial if you are attempting to configure software. It allows users to customize their settings near or beyond their default configuration. Having knowledge of your IP address can aid in managing access to content, networks, and even digital devices, such as printers and routers.
At the same time, it is important to be mindful of the possible risks associated with sharing your IP address. If an outside party has knowledge of your address they could gain access to your network and commit cyber crimes such as malicious intrusions or data theft. In fact, it may even be possible for someone with a valid search warrant to pinpoint your actual location based on geolocation data associated with the IP Address. Therefore, it is vital that users keep security in mind when dealing with any personal information related to their identity online.
IP address vs MAC address
An IP address (Internet Protocol) is a unique set of numbers used to identify a computer or device connected to the internet. It is essential for computers to communicate with one another as well as access the internet, and without it, you wouldn’t be able to send emails or browse websites. Each computer on a network must have its own unique IP address in order for it to communicate with other computers on the same network. Not only does an IP address enable communication between different computers, but it also helps websites know who you are and where you’re located in order for them to provide content specific to your region.
A MAC address (Media Access Control) is another type of address that gets assigned to each individual device connected to a network. This address is embedded in the software of your computer, router, laptop, printer, etc., and serves as a distinct identifier so that data from all devices connected can be separated. Both wireless and wired networks require MAC addresses for accessing the network itself or online services such as webpages and mobile app stores. Because this type of address cannot be changed or duplicated by hackers or attackers, it adds an extra layer of security protection when using a public Wi-Fi connection.
