What is my IPv4 address?
Internet Protocol version 4 is the classic internet addressing standard still used by most connections. This page probes your public IPv4 address via an IPv4-only hostname so dual-stack networks still reveal IPv4.

Why a dedicated IPv4 page
A normal visit to getwhatismy.com may arrive over IPv6 even when you still have a working IPv4 path. This page specifically probes ipv4.getwhatismy.com so you can confirm IPv4 connectivity and copy that address when you need it.
If the result is Unavailable, your path to the IPv4-only host failed—common on IPv6-only networks or when DNS/firewall blocks the probe host.
IPv4 still matters
Most everyday sites and many game/console setups still expect IPv4. Dual-stack users should verify both families; see IPv4 vs IPv6 in Guides and the IPv6 tool for the other side of the stack.

Frequently Asked Questions
What is IPv4?
IPv4 is the classic internet address format (for example 203.0.113.10). Most home and mobile networks still reach websites over IPv4, often alongside IPv6.
Why don’t I see an IPv4 address?
Your network may be IPv6-only, the IPv4 probe host may be blocked, or DNS for ipv4.getwhatismy.com may not resolve. We probe that hostname specifically so a dual-stack page load can still reveal IPv4.
How is this different from What is my IP address?
The main IP page shows both families when available. This page focuses only on IPv4 from the IPv4-only probe host.
How do I prefer IPv4?
- Windows/macOS/Linux:check adapter settings and whether IPv6 is preferred.
- Router:review IPv4 and IPv6 WAN options.
- VPN:some exits are IPv6-only.
- Reload this page after changing to verify.
Do I still need IPv4?
Yes for most everyday browsing today. Many networks and sites still rely on IPv4 even as IPv6 grows.
