What is IP Address?
A unique numerical identifier assigned to every device connected to a computer network. Your IP address reveals your approximate geographic location and can be used to track your online activity, link your actions across websites, and identify your internet service provider.
Also known as: Internet Protocol Address
Your IP address is like your home address on the internet. Every website you visit, every service you use, sees this address—and it reveals more about you than you might think.
What Your IP Reveals
- Geographic location: City, region, sometimes neighborhood
- Internet Service Provider: Who you pay for internet
- Organization: If you're on a company/school network
- Connection type: Home, mobile, VPN, etc.
IPv4 vs IPv6
IPv4
- Format:
192.168.1.1 - ~4.3 billion addresses
- Running out, often shared via NAT
- Most common today
IPv6
- Format:
2001:0db8:85a3:0000:0000:8a2e:0370:7334 - 340 undecillion addresses
- Each device can have unique address
- Growing adoption
Privacy Implications
Tracking
- Websites log your IP with every visit
- Advertisers link activity across sites
- Law enforcement can subpoena ISP records
Identification
- IP + timestamp = your identity (via ISP records)
- Legal actions (DMCA, lawsuits) start with IP
- Shared IPs (NAT) provide some anonymity
Geoblocking
- Services restrict access by IP location
- Streaming rights vary by country
- Some content blocked regionally
Hiding Your IP
VPN
- Replaces your IP with VPN server's IP
- All traffic routed through VPN
- VPN provider knows your real IP
Tor
- Routes through multiple nodes
- Exit node's IP is visible to destination
- Strong anonymity, slower speed
Proxy
- Single intermediate server
- Often not encrypted
- Weaker than VPN/Tor

Related Terms
Proxy
A server that acts as an intermediary between you and the internet. Your requests go to the proxy, which forwards them to the destination. Proxies can hide your IP, bypass geo-restrictions, or filter content—but the proxy operator sees your traffic.
Tor Network
A free, open-source software and network that enables anonymous communication by directing Internet traffic through a worldwide volunteer overlay network of thousands of relays. Tor conceals users' locations and usage from surveillance and traffic analysis.
Virtual Private Network
A technology that creates a secure, encrypted connection over a less secure network, such as the public internet. VPNs mask your IP address, encrypt your internet traffic, and can make it appear as though you're browsing from a different location.
