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.

How is IPv4 different from IPv6?

IPv4 uses 32-bit addresses (e.g. 99.33.79.49) and can represent about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g. 2001:db8::1) and has virtually unlimited capacity. IPv4 addresses ran out globally around 2011; IPv6 was designed to replace it.

What is a private IPv4 address?

Private IPv4 addresses (10.x.x.x, 172.16–31.x.x, 192.168.x.x) are used inside local networks and are never visible on the public internet. Your router, phone, and laptop each have a private IP on your home network, plus they all share one public IPv4.

Why don't I have an IPv4 address shown?

If your ISP uses carrier-grade NAT (CGNAT), you may share a public IPv4 with many other subscribers. In this case, ipnow may show your IPv6 as the primary address. Most users still have some form of public IPv4 routing.

Is my IPv4 address permanent?

Most home connections have a dynamic IPv4 that can change when you restart your router or your ISP reassigns it. A static IPv4 stays fixed and usually costs extra. Business-grade ISP plans often include a static IP.

Understanding IPv4 addresses

What IPv4 is, how it differs from IPv6, and what public and private IPv4 addresses mean for your connection.

What is an IPv4 address?

IPv4 (Internet Protocol version 4) addresses are 32-bit numbers written as four groups of digits from 0 to 255, separated by dots — for example 99.33.79.49. Introduced in 1981, IPv4 can represent about 4.3 billion unique addresses — a supply that has now been exhausted globally.

IPv4 vs IPv6

IPv4 is the original 32-bit format written as four numbers (e.g. 99.33.79.49). IPv6 is the newer 128-bit format created because IPv4 addresses ran out globally. Many connections support both — ipnow detects and displays each separately.

Public vs private IPv4

Your public IPv4 (shown above) is assigned by your ISP and is visible to the entire internet. Private IPv4 ranges — 10.x.x.x, 172.16–31.x.x, and 192.168.x.x — are reserved for local networks and are never routed on the public internet. Your router uses NAT to translate between the two.

Why your IP address changes

Most home and mobile connections use dynamic IP addresses that your ISP can reassign at any time — typically when you restart your router, reconnect, or switch networks. A static IP stays fixed but usually costs extra from your ISP.

IPv4 addresses and your privacy

What your public IPv4 address reveals and how to control who sees it.

What your IPv4 reveals

Your public IPv4 can expose your approximate city, region, and ISP. It does not reveal your name, street address, or browsing history. Every website and service you connect to can see and log your public IPv4.

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.

Masking your IPv4

Use a reputable VPN to replace your real IPv4 with the VPN server's address. Note that if you also have an IPv6 address, you may need a VPN that covers both protocols — otherwise IPv6 can leak your real identity even through the VPN.
