What Your IP
Reveals.

An IP address is your device's home number on the internet. It reveals more than people think and less than VPN marketing claims. Here's the actual breakdown.

What an IP address is

An IP (Internet Protocol) address is a numeric identifier assigned to every device on a network. There are two types in active use:

  • IPv4: 32-bit addresses, written as four numbers separated by dots (192.168.1.1). ~4.3 billion possible addresses. We ran out of these globally around 2011.
  • IPv6: 128-bit addresses, written as eight groups of hexadecimal (2001:0db8:85a3:: 8a2e:0370:7334). ~340 undecillion possible addresses. Designed to replace IPv4 but adoption has been slow.

Your device has at least one IP address, often more (IPv4 + IPv6 + multiple network interfaces). When you visit a website, your packets travel from your device's IP to the website's IP and back.

Public vs private IPs

A common confusion. Your device has two IPs:

  • Private IP: assigned by your local router. Typically looks like 192.168.x.x, 10.x.x.x, or 172.16-31.x.x. Only meaningful inside your home/office network.
  • Public IP: assigned by your ISP and visible to the wider internet. This is the IP websites see when you connect.

Behind a home router, all your devices share one public IP (via Network Address Translation β€” NAT). On mobile data, many users share a single carrier IP (via CGNAT β€” Carrier-Grade NAT).

What your public IP reveals

1. Your ISP

IPs are allocated in blocks to organizations through regional registries (ARIN for North America, RIPE for Europe, etc.). A reverse lookup tells anyone which organization owns the IP block your IP is in. Usually that's your ISP β€” Comcast, Verizon, AT&T, T-Mobile, etc.

This is the most reliable thing an IP tells someone: who you pay for internet access.

2. Approximate geographic location

IP geolocation databases (MaxMind, IP2Location, IPinfo) maintain mappings of IP blocks to geographic regions. They get this data from:

  • ISP-published BGP routing data.
  • WHOIS records (which often list the ISP's billing address, not the user's).
  • Correlation with mobile device location data (controversial).
  • User-reported data.

Accuracy is highest at country level (typically 99%), decent at city level (~70-90% for major cities), and weak at neighborhood/ZIP level (~50% or worse). For ISPs that serve a wide geographic region from a single hub (rural cable, cellular carriers), the accuracy can be terrible β€” showing your "location" as a city 100+ miles away.

3. Your ASN (Autonomous System Number)

Networks on the internet are organized into Autonomous Systems, each with an ASN. Your IP's ASN tells observers which network you're connected through β€” usually overlaps with the ISP but provides more granular detail (e.g., "Comcast Business" vs "Comcast Residential").

4. Whether you're on a VPN, proxy, or Tor

IP intelligence services flag IPs known to belong to:

  • VPN providers (us, Mullvad, NordVPN, all of them).
  • Datacenter / cloud hosting (AWS, Google Cloud, DigitalOcean).
  • Tor exit nodes.
  • Public proxies.

Sites that want to block VPN/proxy traffic use these databases to identify suspicious connections. Streaming services and some banks use them.

What your IP doesn't reveal

  • Your name. The IP-to-customer mapping is held by your ISP. Only legal process (subpoena, court order) can compel that mapping.
  • Your exact home address. See above.
  • Your activity on websites. The IP is just the source/destination identifier; it doesn't carry the content of what you did.
  • Personal details (age, gender, income, etc.). IP-based "demographic" estimates exist but are unreliable inferences, not real data.

How a VPN changes this

When you connect to a VPN:

  • Websites see the VPN server's IP, not yours.
  • The VPN server's IP belongs to the VPN provider, so reverse lookup identifies the VPN, not you.
  • Geolocation shows the VPN server's location, not yours (which may be the same country or a different one depending on which server you picked).
  • The IP is shared with other VPN users, so even within the VPN provider, individual users blend in.

The trade-off: the VPN provider now has a position equivalent to your ISP β€” they can theoretically see your traffic destinations. This is why provider trust matters. A no-log provider (us, Mullvad, IVPN, ProtonVPN) doesn't retain that information, so it can't be subpoenaed, breached, or sold.

IP rotation and dynamic addressing

Most residential ISPs assign IPs dynamically β€” your IP can change when:

  • Your router restarts.
  • Your DHCP lease expires (typically days to weeks).
  • Your ISP reassigns IP blocks for capacity reasons.

Static IPs are uncommon for residential users and usually require paying extra. Business and enterprise accounts more often have static IPs.

Mobile data is even more dynamic β€” your IP can change as you move between cell towers, and CGNAT means you share IPs with many other users.

πŸŽͺ FAQ

Can someone find my home address from my IP?
Not directly. IP geolocation typically resolves to city or ZIP-code-level accuracy at best β€” the precision depends on the geolocation database (MaxMind, IP2Location, etc.) and how much your ISP cooperates. To get from IP to physical address requires either subpoenaing the ISP (which only law enforcement with a court order can effectively do) or correlating the IP with other identifying information leaked elsewhere. The 'IP = home address' assumption is incorrect for nearly all use cases.
What's the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (like 192.168.1.1) β€” about 4.3 billion possible addresses, which we ran out of years ago. IPv6 uses 128-bit addresses (like 2001:db8::1) β€” effectively unlimited. Most home internet still primarily uses IPv4 due to legacy compatibility, with IPv6 deployed alongside it. The main practical difference for users is that IPv6 doesn't require NAT (Network Address Translation), so devices get unique public-facing addresses.
Is my IP unique to me?
Sort of, but it changes. Most residential ISPs assign IPs dynamically β€” your IP may change every few hours, days, weeks, or rarely (depending on your ISP). Mobile carriers usually share IPs across many users via CGNAT (Carrier-Grade NAT), so the IP isn't unique to you at all. Static IPs (where your IP doesn't change) are sometimes available as a paid add-on for business/enterprise customers.
Does my IP reveal what I'm doing online?
Not directly. Your IP just identifies the source/destination of a connection. What you do through that IP β€” which sites you visit, what you buy, what you read β€” is only visible to your ISP (who sees DNS queries and destination IPs) and the sites you visit. Third parties can correlate your IP with their own data (ad networks linking IP + cookies, for example), but the IP itself doesn't tell them what you're doing.
Does ClownVPN give me a static IP?
No β€” all our servers use shared IPs, where many users share the same outgoing IP. This is actually better for privacy: an observer can't say 'this traffic came from a specific user' because there's no 1:1 mapping. Static-IP VPN services exist (a few paid providers offer them for use cases like running self-hosted services or whitelisting), but they reduce the anonymity you get from being one face in a crowd.
