Your public IP address

216.73.216.157
IPv6Not available

This is the address that websites, apps and online services see when you connect. ipnow doesn't store or log it.

Location is estimated from your IP address and may differ from your exact physical location.

Static vs dynamic IP addresses

What each type means, their trade-offs, and how to decide which one you need.

What a dynamic IP is

A dynamic IP is assigned automatically by your ISP from a pool and can change over time — after a router restart, a lease expiry, or a reconnection. Most home and mobile connections use dynamic IPs because they are cheaper and easier for ISPs to manage.

What a static IP is

A static IP never changes — it is permanently assigned to your connection. Businesses use them for hosting servers, running mail servers, remote access, and services that need a fixed, whitelistable address. ISPs usually charge extra for a static IP.

How to tell which you have

Check your public IP now (above), note it, then check again after restarting your router or over a few days. If it changes, you have a dynamic IP. If it stays identical, it may be static — or a sticky dynamic IP that rarely changes. Your ISP can confirm.

The middle ground: DDNS

If you have a dynamic IP but need a stable address (for hosting, RDP, cameras, etc.), Dynamic DNS (DDNS) is the answer. Services like No-IP, Duck DNS, and Cloudflare map a fixed hostname to your changing IP — giving you static-like convenience for free.

Static, dynamic, and your privacy

How your IP type affects trackability and what to do about it.

Static IPs are more trackable

A static IP that never changes makes it easier to associate long-term activity with your connection. Dynamic IPs offer slightly more privacy because they rotate — though your ISP always knows which IP was assigned to you and when.

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.

How to mask your IP

Use a reputable VPN to replace your public IP with the VPN server's address, or the Tor network for stronger anonymity. On Apple devices, iCloud Private Relay (iCloud+) masks your IP in Safari. None of these change your local/private IP — only what the public internet sees.

A static IP is permanently fixed to your connection and never changes. A dynamic IP is assigned from a pool by your ISP and can change over time. Most home users have dynamic IPs; static IPs usually cost extra.
