The internet has become an indispensable part of modern life. We rely on it for work, communication, entertainment and more. But every time we browse the web, make a purchase online or check our email, we leave behind traces of our identity and personal data through our IP addresses.
In this comprehensive guide, you‘ll learn what an IP address reveals about you, who can see your IP, the risks of free proxy services, whether IP tracking is legal, and most importantly – how you can better protect your privacy online through safe solutions like residential proxies and VPNs.
What is an IP Address and What Does it Tell About You?
An IP address is a unique string of numbers separated by dots, assigned to each device connected to the internet. It allows your computer, smartphone and other devices to communicate with websites and other internet-enabled devices.
There are two main types of IP addresses:
IPv4: The most common format, consisting of numbers ranged from 0 to 255 separated by periods. For example,
192.168.1.1. This format provides approximately 4 billion unique addresses.
IPv6: The newest format launched due to IPv4 address exhaustion. It uses hexadecimal numbers and colons instead of dots. For example,
2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 provides an almost unlimited number of address combinations.
|Format||4 sets of decimal numbers separated by dots||8 groups of hexadecimal numbers separated by colons|
|Address Space||4 billion addresses||340 trillion trillion trillion addresses|
|Notation||Dot-decimal notation||Colon-hexadecimal notation|
Your IP address reveals a wealth of information about you and your internet activities to various parties:
IP addresses expose the country, region, city and sometimes even the postal code where your device is connecting from. Geolocation tracking is accurate to within 25-50 kms.
For example, an IP address like
22.214.171.124 can be pinned to Los Angeles, California based on the ISP and IP location databases.
According to a 2022 survey, 87% of consumers are concerned about how much of their location data is exposed online.
ISP and Network Information
The first sets of an IP address digits indicate the identity of your internet service provider. This gives away your broadband company or mobile carrier along with your approximate area.
Certain number blocks are exclusively allocated to specific ISPs. For instance, IPs starting with
67.131.x.x belong to Comcast subscribers in the United States.
The rest of the IP reveals details about the internal network you‘re connecting through. Tech professionals can identify your network topology, hardware devices, configurations and more.
Browsing History and Habits
Websites and ad networks record and analyze your IP address to understand your browsing activities and build an interest profile. They can tie various sessions across sites to your IP address and create a log of your:
- Viewing history
- Videos watched
- Links clicked
- Searches made
- Pages visited
Even when in incognito mode or after clearing cookies, your IP address remains visible and traceable across the web.
In a 2021 survey of 1200 consumers, over 80% were uncomfortable with advertisers tracking their web history and habits for targeting ads based on their IP address.
Personally Identifiable Information
While IP addresses themselves don‘t contain personal info, they can be tied to your name, email, physical address and other details held by your ISP or sites and services you signed up for.
Authorities or hackers who obtain your IP can request or extract your PII from these sources through a subpoena or database breach. According to cybersecurity analysts, over 90% of consumers‘ personal information can be uncovered just by accessing their IP address.
This is why many people prefer to hide their IP address while browsing. But who exactly can see your IP address as you surf the web?
Who Can View and Track Your IP Address?
A wide range of entities and individuals beyond just websites can easily access your IP address:
Websites and Apps: All websites and services you interact with receive your IP address to identify your device and location. This data is logged and analyzed to understand their users.
Your Internet Service Provider: ISPs inherently have visibility into the IP addresses they assign subscribers on their network. They can view all your web activity.
Advertisers and Trackers: Ad networks and platforms use IP addresses for targeting relevant ads based on your location and interests gleaned from your browsing habits.
Government Authorities: Law enforcement agencies can legally compel ISPs to hand over subscriber data including IP addresses to identify suspected criminals.
Malicious Hackers: Cybercriminals actively try to steal IP addresses through phishing attacks, malware, WiFi snooping and more. They can sell this data or use it to infiltrate systems.
Public WiFi Providers: On public networks like cafes, airports etc. the WiFi provider has access to view and log the IP of all connected devices.
Employers and Schools: Large companies and schools often monitor employee and student internet access including their IP addresses through the organization‘s network.
Other Users on the Network: Savvy users connected to the same network may be able to intercept your IP address through techniques like ARP spoofing despite security protocols like DHCP.
According to cybersecurity researchers, the average internet user‘s IP address is logged over 2000 times per day on average by websites, ad platforms and ISPs. This data can be aggregated to track your digital footprint.
Should You Use Free Proxy Services or Fake IP Generators?
To prevent tracking and hide their IP address online, some users turn to free proxy services or fake IP address generator tools. However, these often provide a false sense of security and can seriously jeopardize your privacy.
Significant Privacy and Security Risks
While free proxy services sound very appealing, you must keep in mind that you‘re essentially handing over your web data and identity to an unknown entity:
Injected Ads and Trackers: Free proxies frequently inject additional ads, trackers and monitoring code into the web pages and traffic passing through them. This allows them to profit off your data.
Malware and Viruses: Shady free proxies may inject malware or viruses along with ads to infect users‘ devices. According to a Symantec study, 1 in 3 free proxies contained malware or suspicious activity.
Logging and Reselling Data: Free proxies monitor and log all your activity and can sell your sensitive browsing data including usernames, passwords and interests to undisclosed third parties.
No Encryption: Traffic flowing through free proxies is unencrypted by default, making it easy for hackers to intercept credentials and data.
No Real Anonymity: They can still view and log your real originating IP address behind the proxy, completely negating anonymity.
Limited Speeds: You‘ll likely experience very slow internet speeds and frequent disconnections with free proxies.
Researchers evaluating the privacy policies of free proxy services found over 85% of them reserve the right to collect user data and share it with partners.
Fake IP Address Generators Don‘t Work
Tools that claim to generate fake or random IP addresses don‘t actually provide any real privacy protection. They simply generate random sets of digits formatted like legitimate IP addresses.
But these fake IPs are not assigned to any real proxy servers or devices. Websites and services you attempt to access will immediately see your real IP address behind the fake one and can track you normally.
The only effective way to mask your IP address is by routing your traffic through legitimate proxy server IPs or VPNs, which essentially replace your real IP on the front-end.
Is Tracking and Grabbing IP Addresses Legal? Can You Spoof IPs?
IP Address Tracking
There are no federal laws in the United States explicitly regulating the tracking and logging of IP addresses. In general, it‘s legal for websites, ad networks, authorities and ISPs to record IP addresses for business purposes like analytics, network security and forensics investigations.
However, some state privacy laws like CCPA in California provide residents certain rights over their data including IP addresses that businesses must respect.
Using or selling individuals‘ IP addresses without consent for malicious purposes like identity theft or hacking is illegal under cybercrime laws.
IP Address Spoofing
Spoofing refers to masking your real IP address with a fake address, often to bypass access controls or make attacks harder to trace back.
Spoofing your IP is illegal if done with malicious intent such as:
- Hacking into computer systems or accounts
- Spreading malware, viruses and ransomware
- Launching DDoS attacks to take down networks
- Committing credit card or identity fraud
However, using legitimate proxy and VPN services to access blocked content or simply maintain privacy is typically legal in most countries. However authoritarian regimes do criminalize usage of VPNs and proxies.
For instance, a UK man faced criminal charges for accessing US Netflix through IP spoofing. But he successfully argued this was done solely to access geo-blocked content, not illegally infiltrate networks. The judge ruled in his favor, noting problems with region-locking content.
Should You Use Proxies or VPNs to Hide Your IP Address?
Proxies and VPNs are the two best options to hide your real IP address while browsing the web safely and legally. But how do they compare for privacy?
How Proxy Services Work
Proxy servers act as intermediaries that route your web traffic requests through their IP addresses before accessing the destination site. When you use a proxy, websites will see the proxy‘s IP instead of your own.
Different types of proxies include:
Residential proxies using IPs of real devices to provide high anonymity.
Datacenter proxies using IPs of servers housed in datacenters.
Rotating proxies that automatically rotate IP addresses with each request.
Backconnect proxies where IPs are rotated using a large proxy pool.
Benefits of Proxies
Hide your IP on browser level for web anonymity
Unlimited number of new IP addresses depending on pool size
Faster speeds than VPNs as only routing web traffic
Cheaper pricing options than VPNs
Limitations of Proxies
Only work at browser level, not device level like VPNs
Traffic not encrypted by default unless specifically configured
How VPN Services Operate
VPN stands for Virtual Private Network. VPNs route all your device‘s internet traffic through an encrypted tunnel to the VPN server. This assigns you a new virtual IP address and masks your original one.
VPNs encrypt all your computer or smartphone‘s internet traffic and also change your virtual location. Popular VPN protocols include OpenVPN, IKEv2, WireGuard® etc.
Benefits of VPNs
Encrypt all your device‘s internet traffic
Completely mask device‘s real IP address
Allow accessing region-blocked content
Advanced security features like kill switches and zero log policies
Drawbacks of VPNs
Significantly slow down internet speeds due to encryption overhead
Limited to preset number of shared IP addresses across all users
More expensive than proxies with rates ~$5-15/month for individuals
Only useful for device-level privacy, not browser-only needs
Should You Use Proxies or VPNs?
For most basic web browsing and internet privacy needs, experts typically recommend paid proxy services over VPNs. Here‘s why:
Proxies are 3-4x cheaper than VPNs on average, with prices starting under $1/month through providers like GeoSurf, Luminati, and Oxylabs.
Residential proxies offer higher anonymity with IP diversity than VPNs sharing small server pools across all users.
Proxies don‘t impact web speeds as significantly since they only reroute web traffic. VPN encryption introduces latency.
For web use cases like ad verification, data scraping, accessing sites anonymously etc. proxies get the job done with faster performance.
VPNs add unnecessary encryption overhead if you just want to hide your IP for general browsing or access certain sites.
Of course advanced use cases like torrenting or accessing public WiFi absolutely warrant the encryption and device-level privacy of quality VPNs despite the speed tradeoff.
But for most consumers concerned about IP address tracking and basic web anonymity, expert proxy services like BrightData, Oxylabs and GeoSurf are the most ideal choice balancing privacy, speed and affordability.
Key Takeaways to Protect Your Online Privacy
Your IP address provides a digital fingerprint that can reveal location, browsing history and other personal details to websites, ISPs, hackers and more.
Free proxy services and fake IP generators often jeopardize your privacy instead of protecting it. Avoid them.
Tracking and logging IP addresses is generally legal, but spoofing IPs for malicious attacks is illegal.
For basic web use cases, expert proxies offer the best balance of security, performance and pricing over VPNs.
Invest in a reputable paid proxy service to hide your IP if you are concerned about online tracking and anonymity based on cybersecurity experts‘ recommendations.
The bottom line is your IP address exposes much more personal information than you probably realize as you browse the web daily. Take prudent steps like using secure proxy connections to better protect your privacy and identity online.
