What can someone do with your IP Address?

We frequently emphasize the significance of your IP address in our security guides. However, why is it critical? If obtained by a malicious party, your IP address can lead to various damaging consequences, such as spam or computer attacks. This guide outlines the potential dangers of IP address exposure and provides practical tips to safeguard this sensitive information.

What is an IP address?

An IP address, or internet protocol address, is a set of numbers that serves as a unique identifier for your device and its location on the internet. It is essential for the functioning of the internet as it allows devices, networks, and websites to be differentiated from one another.

Each device has both an external (public) and an internal (private) IP address. The external address identifies your router and your general location, while the internal addresses distinguish devices within your home network.

Your devices may have two types of IP addresses: IPv4 and IPv6. IPv4 is the most commonly used address system and was introduced in 1983. However, with the concern that all IPv4 addresses would eventually be exhausted, a more complex system with more characters, known as IPv6, was introduced in 1999.

The Importance of Protecting Your IP Address

Safeguarding yourself against online threats is crucial, and one effective way to do so is through a virtual private network (VPN). A VPN conceals your genuine IP address and replaces it with its own, preventing websites from seeing your actual location. It also encrypts your internet traffic, ensuring secure browsing. We’ve conducted extensive testing on numerous VPNs and identified the top three options that provide the highest level of protection.

What Can Someone Do With Your IP Address?

Send spams: Sophisticated advertisers now use tracking programs embedded in online articles to note your IP address and send spam messages based on your browsing. For instance, after reading an article on how to do dolled makeup, you might start receiving emails from local makeup shops.

Know your location: By determining your IP address, it is possible to figure out the city you are located in, and potentially even your home address by exploring the internet. Some burglars monitor social media to detect when homeowners are away, and with access to IP addresses, it becomes easy for them to target specific houses. Therefore, it is important to take measures to secure your home when you are away.

Limit your availability to specific online offerings: Your geographic location is crucial for some online services. They use your IP address to detect your whereabouts and limit your access to their content. For instance, YouTube TV restricts your access to local channels based on the city you reside in. Similarly, Netflix determines your country of origin and restricts access to that country’s library of movies and TV shows, unless you modify your Netflix region with a Netflix VPN.

Restrict you from playing games: In the context of online gaming, if you manage to beat a game administrator and they become unhappy with you, they may ban you from the match. This ban could then lead to your IP address being blacklisted from the entire website, which would prevent you from playing any games on that site.

Deploy DoS/DDoS attacks: To carry out a DoS (denial of service) attack, a person can use your IP address. These attacks prevent you from accessing network resources such as websites, online accounts, and emails. The typical approach for such attacks is to send a high volume of server requests to your address, overloading and disrupting your system with traffic. In the case of a DDoS attack, the process is similar, but involves multiple machines generating even more traffic. Therefore, people often use VPNs to prevent DDoS attacks.

Get access to your personal information: Gather sensitive information about you: Cybercriminals are always on the lookout for Personally Identifiable Information (PII) which they can use to commit fraud or impersonate you. Examples of PII i.e. phone number, security number, mailing address, and date of birth, all of which are valuable for identity thieves. Although your IP address is not classified as PII, if a hacker obtains it, they can use it to locate your Internet Service Provider (ISP). This information can then be used in a phishing attack to trick the ISP into revealing any PII they have on file for you. One effective way to protect yourself against identity theft is to invest in a high-quality identity theft protection service.

Impersonation: A hacker with enough skills can use your IP address to pretend to be you online, routing their activity with address. This can lead to false accusations of illegal activities like downloading child pornography, buying drugs or even causing security threats.

Dark web selling: Some thieves are not interested in impersonating you but rather in stealing your IP address and selling it on the dark web. To prevent this scenario, consider using one of the best identity theft protection services with dark web monitoring.

Activity tracking: Many employers want to monitor their remote workers’ activities by tracking their IP addresses, which is an invasion of privacy.

Copyright infringement lawsuits: In many countries like U.S., strict copyright laws monitor torrenting services to identify IP addresses associated with protected content downloads. Law enforcement agencies can demand ISPs to disclose the names and addresses of users associated with those IP addresses, which can result in copyright infringement lawsuits. Using one of the best VPNs for torrenting can help prevent this scenario.

How Can Someone Obtain Your IP Address?

Locating your IP address isn’t that difficult as it’s not considered personally identifiable information (PII), and most services & companies don’t take extra measures to conceal it. The following are some sources through which someone can obtain your IP address:

• Emails: Some email servers may reveal your IP address in the email header. You can opt for email services such as Gmail that don’t do this if you’re concerned.
• Torrenting: When torrenting, your IP address can be seen in the peers list. However, you can use a VPN for torrenting to bypass this issue.
• Phishing Attacks: Your IP address can become vulnerable to hackers if you respond to phishing attacks or click on suspicious links.
• Online Ads: Legitimate ads may record your IP address if you select them. This is known as adware, and it’s how many companies conduct their business. Fortunately, there are effective methods available for removing adware.
• Your Computer: It’s simple for someone to search the IP address in the device settings if you lend your device to someone, even for a short period.

Ways to Protect Your IP Address:

• Update your firewall: Ensure that you use secure passwords for your firewall, router, devices, and accounts, and update them regularly. This will help prevent breaches to your security.
• Change your privacy settings: Set your messaging apps to private and avoid accepting calls or messages from unknown people to prevent hackers from accessing your IP address through messaging apps like Skype.
• Use a VPN: A virtual private network traces your internet activity through multiple servers and provides you a new IP address that cannot be traced back to you.
• Use a proxy server: Proxy servers hide your IP address, but do not provide high-end encryption to protect your online activity.
• Use Tor software: Tor is a web browser that allows you to browse online anonymously, hiding your IP address by routing it through an open-source network of other Tor users. Despite a breach in 2019, Tor has fixed the issue.
• Switch to mobile data: Mobile data does not involve IP addresses. If you have enough data, switching to mobile data ensures that you don’t have to worry about IP address leaks.
• Talk with your ISP: If you’re especially concerned about IP address security, you can chat with your ISP about assigning you an IP address that is dynamic and changes regularly.
