What is my IP address?

Your IP address is a unique number that identifies your device on the internet. ipnow detects and displays your public IPv4 and IPv6 address at the top of this page automatically.

How do I find my IP address?

The fastest way to find your IP address is to open ipnow.dev — your public IP is shown instantly. No app, sign up or technical knowledge required.

What is the difference between IPv4 and IPv6?

IPv4 is the older 32-bit address format (e.g. 99.33.79.49). IPv6 is the newer 128-bit format that provides many more addresses. Many devices now have both.

Why is my mobile IP different from my Wi-Fi IP?

Wi-Fi and mobile data are separate network connections from different providers. Your home router's ISP provides the Wi-Fi IP; your mobile carrier provides the cellular IP. They are completely independent addresses.

Why does my mobile IP keep changing?

Mobile carriers use dynamic IP assignment and carrier-grade NAT. IPs change as you move between towers, switch network types (LTE → 5G), or when the carrier recycles addresses. This is normal — mobile IPs are far less stable than home internet IPs.

Can I get a static IP on mobile data?

Some carriers offer static mobile IPs on business plans, but it's rare on consumer plans. Most mobile users have dynamic IPs that change frequently due to carrier-grade NAT and network handoffs.

Does a VPN on my phone change my mobile IP?

Yes. When connected to a VPN on your phone, all traffic goes through the VPN server, and websites see the VPN's IP instead of your carrier's IP. Your carrier sees only that you're connected to a VPN, not where your traffic is going.

What is my mobile IP address?

Your mobile data IP address is assigned by your carrier and is shown above. It's the address websites see when you browse on 4G or 5G, not your home Wi-Fi.

Mobile IP addresses explained

How your carrier assigns your mobile IP, why it often differs from your Wi-Fi IP, and what changes as you move between towers.

How mobile IPs work

When you connect via mobile data (4G or 5G), your carrier assigns your device a public IP from its network. Many carriers use carrier-grade NAT (CGNAT), which means you share a public IP with many other subscribers. This is different from a home internet connection where your router gets a dedicated IP.

Why mobile IPs change frequently

Mobile IPs are highly dynamic — they change as you move between cell towers, switch from LTE to 5G, or when your carrier reassigns addresses. Unlike home internet, where an IP can stay the same for weeks, mobile IPs may change multiple times per day.

Switching between Wi-Fi and mobile data

Your public IP changes when you switch between Wi-Fi and mobile data. On Wi-Fi, your IP comes from your router's ISP connection. On mobile data, it comes from your carrier. Turn off Wi-Fi and reload ipnow.dev to see your carrier's IP on its own.

Privacy on mobile data

Carrier-grade NAT means many users share your mobile IP, making individual identification harder than on a dedicated home IP. Still, your carrier tracks your identity and data usage. A mobile VPN encrypts your traffic and hides your browsing from your carrier.

Mobile IP addresses and your privacy

What your carrier can see, what websites can determine from your mobile IP, and how to stay private on mobile data.

What your mobile IP reveals

Your mobile IP reveals your carrier, approximate region, and connection type (mobile vs residential). Because mobile IPs are often shared via CGNAT, they are less uniquely identifying than home IPs. However, websites can still geolocate you to a city or region level.

We never log it

ipnow shows no ads and runs no trackers. We never store or log your IP address on our servers. Geolocation and ISP details are fetched from privacy-respecting third-party providers.

Protecting privacy on mobile data

Use a reputable VPN app on your mobile device to encrypt traffic and mask your carrier IP from websites. Enable Private DNS (Settings → Network → Private DNS on Android, or use a DoH-enabled browser) to hide your DNS queries from your carrier.
