IP address definition

An IP address refers to a unique address that identifies an internet device or local network. IP stands to represent "Internet Protocol", which is the set of rules that govern how data is sent over the internet or on a local network.
IP addresses are, in essence, the identifier that allows information between devices on a network. They include location information and allow devices to communicate. The internet requires a way to distinguish between different computers and routers. It is essential that the internet functions by using IP addresses.

What is an IP?

An IP address can be described as a string of numbers separated apart by periods. An IP address can be described as a collection of four numbers. A simple example might be Each number in this set can have a range of 0 to255. Also, the IP addressing range can be from to
IP addresses do not happen randomly. They are mathematically created and allocated by the Internet Assigned Numbers Authority. This is a division of Internet Corporation for Assigned Names and Numbers. ICANN is a non-profit organization. It was established in the United States to protect the internet and make it usable for all. A domain name registrar is required to register a domain.

How do IP addresses work?

Understanding how IP addresses work is a great way to find out why a device doesn't connect the way you expected.
Internet Protocol works in the same way as any other language. All devices communicate using the same guidelines to exchange information. All connected devices can find, send, or exchange information using this protocol. Computers can communicate by using the same language from any location.
Most often, IP addresses are used behind the scenes. It works this way:
  • Your device is indirectly connected to the internet via a connection to a network-connected first to the internet. Then, your device can access the internet.
  • If you are at home, it will be your Internet Service Provider. It will be your work network.
  • Your ISP assigns you an IP address.
  • Your internet activity will go through the ISP and they will route it back towards you using your IP Address. Because they give you internet access, it is their responsibility to assign an IP to your device.
  • But, your IP address may change. You can change your IP address by turning your router or modem on or off. Your ISP can make the change for you.
  • If you are traveling, and your device is with you, you will not be able to take your home IP address with you. This is because you'll be connecting to another network (WiFi in a hotel, airport or coffee shop). You will use a temporary (and different) IP address to access the internet. It is assigned by your ISP.
  • Types and types of IP addresses

    IP addresses of consumers

    Every person and every business that uses an internet service plan has two types of IP addresses exist: private IP addresses and public addresses. The terms private and public refers to the location of the network -- that is, a private address is used inside a network and a public address is used outside.

    Private IP addresses

    Every device that connects via your internet network is assigned a private IP. This includes smartphones, tablets, and computers. It also covers any Bluetooth-enabled device like printers, speakers, and smart TVs. You are likely increasing the number of private IP addresses in your home due to the growing Internet of things. These items must be identified by the router separately. Many items also need to be able to recognize one another. Your router creates unique IP addresses that identify each device on the network.

    Public IP addresses

    The public IP address is your network's primary address. Although each device connected to the network has its own unique IP address, they all are included in the main Internet address. Your ISP will provide your router with your public IP address, as explained above. ISPs usually have large numbers of IP addresses that are distributed to their customers. Your public IP Address is the address that devices outside of your internet network will use in order to recognize your network.

    Public IP addresses

    Public IP addresses can be either static or dynamic.

    Dynamic IP addresses

    Dynamic IP addresses can be changed automatically and frequently. ISPs acquire large amounts of IP addresses from various sources and assign them to their customers. They periodically re-assign the IP addresses and add the older ones to the pool to be used by other customers. This approach allows the ISP to reduce costs. The ISP doesn't need to take any specific actions to re-establish an IP address for a customer who moves home because they automate the regular movement. A changing IP address can make it more difficult for criminals to hack into your network's interface.

    IP addresses that are static

    Static addresses are more consistent than dynamic IP addresses. The IP address is assigned by the network and it stays the same. While most individuals and businesses do NOT require a static IP address for their servers, businesses who plan to host them will need one. Because a static IP address ensures websites and email addresses that are tied to it will have a consistent address. This is crucial if other devices want to find them consistently online.

    There are two types of IP addresses for websites

    There are two types of website owners that don't have their own server but rely on web hosting packages. These IP addresses can be either dedicated or shared.

    IP addresses that are shared

    Websites that use shared hosting plans from web hosts will usually be one of several websites on the same server. This is often true for smaller websites or websites that are small in traffic. The sites are also limited in number and pages. This will result in shared IP addresses for websites hosted this way.

    IP addresses dedicated

    You can purchase a dedicated IP address, or multiple addresses, with some web hosting plans. This makes it easy to get an SSL certificate. It also allows you the ability to create your own File Transfer Protocol Server (FTP). This makes it easy to share files with multiple people in an organization. It also allows anonymous FTP sharing. You can also access your website via a dedicated IP address, rather than your domain name. This is useful if your goal is to create and test it before you register your domain.

    How to find your IP address

    Google searches "What is my address?" to determine your router's IP address. Google will provide the answer at top of the page.
    Platforms may vary in how you can find your private IP address:
    In Windows:
  • Use the prompt command.
  • Windows search allows you to search for "cmd", but without the quotes, using Windows search
  • Enter "ipconfig", without quotes, in the popup box to get the information.
  • On a Mac:
  • Go to System Preferences
  • Select network - information should be visible
  • iPhone:
  • Go to Settings
  • Select Wi-Fi and click the "i", in a circle (), next to the network. The IP address should appear under the DHCP Tab.
  • Go to the router if you want to see the IP addresses of any other devices on the network. The brand and software you use will affect how you access the router. You should be able to enter the router's gateway IP into a browser on the same network. The next step is to navigate to "attached devices", which will display a list of all of the devices that are currently attached or have been attached to the network.

    Security threats to IP address

    Cybercriminals may use a variety of methods to gain your IP address. Online stalking and social engineering are the two most common methods.
    Social engineering is a way for attackers to trick people into giving their IP addresses. They could find you using Skype or similar instant messaging apps that use IP addresses to communicate. You can also see the IP address of strangers you chat with through these apps. Hackers have the option to use the Skype Resolver tool that allows them to locate your IP address by your username.

    Online stalking

    By simply following your online activity, criminals can easily track your IP address. You can easily reveal your IP address by playing online games or commenting on sites and forums.
    Once they have your IP address, attackers can go to an IP address tracking website, such as, type it in, and then get an idea of your location. If they wish to confirm that your IP address is associated with someone, they can cross-reference data from other open-source sources. They can then use LinkedIn, Facebook, or other social media networks to show your location and see if it matches the given area.
    A Facebook stalker would use a phishing attack to target people with your username to install spying malware. The IP address associated with your system would likely confirm that you are the stalker.
    Cybercriminals have access to your IP address and can launch attacks against or impersonate you. It is vital to be aware of the potential risks and how to minimize them. Here are some examples of risks.

    Your IP address is used to download illegal content

    Hackers can use hacked IP addresses for illegal content downloads and any other information they don't want to be tracked back to them. Criminals could use your IP address to download pirated videos, music, and movies. This would be against your ISP's terms. It also makes it possible for them to access content that may relate to terror or child pornography. This could result in you being investigated by law enforcement even though you are not at fault.

    Finding your exact location

    Geolocation technology can be used by hackers to identify your state, region, and city if they have access to your IP address. You will only need to go through social media and identify your house, so they can burgle it.

    Your network can be directly attacked

    Criminals have the ability to target your network and launch various attacks. The most well-known is the DDoS attack. This refers to distributed denial-of-service attacks. This cyberattack is when hackers infect machines previously used to flood a server or system. This increases the server's workload, leading to a disruption in services. This basically shuts down the internet. Although this is more common for businesses and gaming services, it can also happen to individuals. Online gamers are particularly at risk because their screen is visible when streaming (on which an Ip address can also be discovered).

    Hacking into your device

    Your IP address is not enough to establish a connection with the internet. The internet also uses ports. Every IP address has thousands of ports. A hacker can attempt to force an internet connection by trying those ports. They could, for example, take control of your phone to steal your personal information. If they do gain access to your phone, they can install malware.

    How to protect and hide IP addresses

    You can hide your IP address online to protect your identity. These are the two most common ways to hide IP addresses:
  • Proxy server
  • Utilizing a virtual private network (VPN)
  • A proxy server is an intermediary server that routes your traffic.
  • The IP address of the proxy server is what internet servers see. It does not show your IP address.
  • Information sent by these servers to you is passed to the proxy server. This then routes it to your computer.
  • Proxy servers can spy on you, so make sure you trust them. You may also get ads depending on which proxy server you choose.
    VPN offers a better way to do this:
  • The VPN acts as though your device is connected to the same network as the VPN.
  • All of your network traffic is sent via a secure connection to VPN.
  • You can securely access local network resources even if you're not in the same country as your computer.
  • You can use the internet just like you were at the VPN site. This is especially useful if your location is public Wi-Fi and you want to access geo-blocked websites.
  • When to use VPNs

    VPNs hide your IP address and send your traffic to a different server. This makes it more secure online. You might consider using a VPN in these situations:

    Use public Wi-Fi

    It is best to use a VPN when you are using a public Wi-Fi network. Hackers can easily access your data by connecting to the same Wi-Fi network. The basic security of a public Wi-Fi network does not offer strong protection against other users.
    A VPN provides additional security by encrypting all communication and bypassing public Wi-Fi ISPs.

    When you travel

    A VPN can be used to allow you access services not available in your destination countries, such as Facebook and China.
    VPNs can allow you to stream streaming services you pay for and have access to in your home country. However, they may not be available in another country due to international rights issues. A VPN will allow you to use the service like you are at home. Travelers might also find it easier to get cheaper airfare by using a VPN. Prices can vary widely from one region or another.

    Working remotely

    This is particularly important in the post COVID world where many people work remotely. Many employers require that a VPN be used to remote access company services. VPNs that connect to your company's server allow you to access internal network resources and other resources even if you are not there. The VPN can connect to your home network from anywhere you are.

    For those who just need some privacy

    Even if you are not using the internet daily, a VPN can help. The server that connects to your computer logs your IP address. It also attaches this data to any other data about you such as browsing habits, what pages you view, how much time you spend on a particular page, etc. These data can be sold to advertisers who then tailor ads directly to your interests. It's why advertisements on the internet feel so personal. Your IP address can be used even if your location services have been disabled to track your exact location. A VPN protects you from leaving any footprints online.
    You should also not forget your mobile devices. Your mobile devices have IP addresses, so you can use them in many more locations than your home computer. A VPN is recommended for your mobile to connect to networks you might not trust.
