Hide your original public IP, encrypt your connection, and take control of your virtual location. Use BearVPN to browse more privately and break through network restrictions.
IPv4 and IPv6 describe the address version. Public and private describe how an address is used: on the internet or within a local network. An IPv4 address can be public or private.
Compare IPv4 and IPv6 address formats, capacity, and configuration. Connection speed and security depend on the network and its setup, not just the IP version.
| Feature | IPv4 | IPv6 |
|---|---|---|
| Address Size | 32-bit (about 4.3 billion addresses) | 128-bit (340 undecillion addresses) |
| Address Format | Four decimal numbers, e.g., 192.168.1.100 | Colon-separated hexadecimal groups, e.g., 2001:db8::1 |
| Address Exhaustion | Limited address space; sharing and reuse are common | Vastly larger address space for continued network growth |
| Performance | Speed depends on routing and network conditions | Speed depends on routing and network conditions |
| Security | Does not encrypt traffic by default; can use IPsec | Does not encrypt traffic by default; can use IPsec |
| Compatibility | Widely supported across networks and services | Requires IPv6 support along the connection path |
| Network Address Translation (NAT) | Commonly used to share a public address | Usually unnecessary for address conservation |
| Configuration | DHCP or manual configuration | SLAAC, DHCPv6, or manual configuration |
Why does your device show a different IP from this page? On a typical home IPv4 network, your devices use private addresses and share a public IP for internet access.
| Aspect | Public IP | Private IP |
|---|---|---|
| Purpose | Used for communication over the internet | Used for internal communication within a local network |
| Assignment | Provided by an ISP, or used as an exit address by a VPN or proxy | Usually assigned by your router; can also be set manually |
| Uniqueness | Globally unique address; may be shared by multiple devices or users | Unique within its local network; reusable in other networks |
| Example | 4.4.4.4 | 192.168.1.100 |
| Where to Find It | In the IP checker at the top of this page | In your device’s Wi-Fi or Ethernet settings |
