What is a public IP address and why it matters

Public IP vs Private IP

Every Internet-connected device has two types of IP addresses: a public one and a private one. The public IP is assigned by your ISP to your router and is visible to any server on the Internet. The private IP (typically 192.168.x.x or 10.x.x.x) identifies the device within the local network and is not reachable from outside.

Knowing your public IP is useful for remote access, home servers, VPNs and online gaming.

IPv4, IPv6 and address exhaustion

IPv4 uses 32-bit addresses (~4.3 billion total). As connected devices multiplied, the IPv4 pool was exhausted. IPv6 solves this with 128-bit addresses (≈3.4×1038). Many ISPs now assign both IPv4 (often via CGNAT) and native IPv6 — if both fields show values, your connection is dual-stack.

IP Geolocation: accuracy and limitations

IP geolocation estimates your physical location from public databases that map IP ranges to cities and regions. Accuracy varies: in residential settings it may be close to your real city, but with a VPN or in corporate environments it could be hundreds of kilometres off. Data shown here must not be used for legal or surveillance purposes.

How to use the API

The service exposes four free public endpoints, usable from any script or application.

1. Plain text — IPv4 and IPv6
Returns the IPv4 and IPv6 address on two separate lines. If a protocol is not available, NONE is returned.
curl https://ippubblico.org/?text=1
Response: IPv4: 93.45.12.88 / IPv6: NONE

2. Full JSON
Returns a JSON object with IP, ISP, ASN, geolocation, timezone and HTTP headers.
curl https://ippubblico.org/?api=1

3. IPv4 only
Returns only the IPv4 address as plain text, or NONE.
curl https://ipv4.ippubblico.org

4. IPv6 only
Returns only the IPv6 address as plain text, or NONE.
curl https://ipv6.ippubblico.org

What your IP address reveals — and what it doesn't

Your public IP address exposes a limited but meaningful set of information to any server you connect to: your approximate location (usually city or region, rarely the exact street), your Internet Service Provider (ISP), and your ASN (the network block your IP belongs to).

What it does not reveal: your name, home address, phone number, device type, or browsing history. Law enforcement can obtain identity details by subpoenaing your ISP, but websites cannot do this on their own. Despite common misconceptions, simply knowing someone's IP is not enough to identify them without legal process.

Static vs dynamic IP addresses

Most home users receive a dynamic IP — an address that can change each time your router reconnects to the ISP, or after a lease period (typically 24–48 hours). Dynamic IPs are cheaper for ISPs to manage and provide a basic layer of privacy through address rotation.

A static IP is permanently assigned to your connection and never changes. It is useful for hosting servers at home, running a VPN endpoint, or maintaining consistent access to remote systems. Static IPs usually cost extra and are primarily offered on business plans.

CGNAT: why your public IP may be shared

Many ISPs — especially mobile carriers and smaller broadband providers — use Carrier-Grade NAT (CGNAT). Instead of giving each customer a unique public IPv4, they pool many customers behind a single IP using port mapping.

The consequences: multiple households share the same public IPv4 address simultaneously. This can cause issues with services that track users by IP (such as banning one user may affect others), and it makes hosting a server from home impossible without additional configuration.

CGNAT is one of the main drivers pushing ISPs towards IPv6 deployment, where every device can receive its own globally unique address.

How to hide or change your IP address

There are three main methods to mask your public IP address:

1. VPN (Virtual Private Network) — your traffic is encrypted and routed through a VPN server, so websites see the VPN server's IP instead of yours. Best for privacy, streaming geo-restricted content, and protecting data on public Wi-Fi.

2. Proxy server — acts as an intermediary between your browser and the website. Faster than a VPN but typically unencrypted and limited to specific applications. Free proxies are often unreliable or insecure.

3. Tor network — routes your traffic through at least three volunteer-operated relays, making tracing extremely difficult. Very strong anonymity but significantly slower than VPN or proxy. Suitable for high-privacy needs rather than everyday browsing.

Frequently asked questions about public IP

Just open IPPubblico.org — the system automatically detects your public IPv4 and IPv6 address with no registration or installation required.
Your public IP is visible on the Internet and assigned by your ISP to your router. Your private IP (e.g. 192.168.x.x) is assigned by the router to devices on your local network and is not reachable from outside.
Most ISPs assign dynamic IP addresses. To always have the same address, you need to request a static IP, usually for an additional fee.
No. IP geolocation provides an approximate location (city or region), not a precise physical address.
An ASN (Autonomous System Number) is a unique identifier assigned to a group of IP networks managed by a single operator, used for Internet routing.
You can mask your IP using a VPN, a proxy server or the Tor network.
A dual-stack connection supports both IPv4 and IPv6 simultaneously, ensuring compatibility with all Internet services.
The service logs the IP and session metadata for statistical purposes for a maximum of 90 days. No data is shared with third parties or used for profiling.
Knowing your IP address alone is not sufficient to hack a device. An attacker would also need an open vulnerable port and exploitable software. However, IP addresses can be used in DDoS attacks or targeted port scanning. Using a VPN reduces this exposure.
IP geolocation databases map IP ranges to locations using data from ISPs and public registries. The location shown is often where your ISP's regional infrastructure is located, not your exact address. Discrepancies of 50–200 km are common for residential connections.
Carrier-Grade NAT (CGNAT) means your ISP shares one public IPv4 address across multiple customers. You can check if you're behind CGNAT: if the 'public' IP shown by your router differs from the IP shown here, you are behind CGNAT. This affects port forwarding and hosting services from home.
IPv4 uses 32-bit addresses (e.g. 93.45.12.88) with a theoretical maximum of ~4.3 billion unique addresses. IPv6 uses 128-bit addresses (e.g. 2001:db8::1) with a virtually unlimited pool. IPv4 addresses were officially exhausted globally in 2019. Most modern connections support both simultaneously (dual-stack).
