Check your public IP address instantly. See your IPv4, IPv6, ISP, ASN, hostname, location, browser details, VPN status, DNS leak, and WebRTC leak information.
Your IP address is the public network address websites see when your device connects to the internet. When you search what is my IP, whats my IP, my IP address, or check my IP address, you are usually looking for the public IP assigned by your internet service provider, mobile network, VPN, proxy, or office network. This address helps websites send data back to your device and can also show basic network information.
NetsTool IP checker shows your public IP address instantly with useful details in one place. Instead of showing only a number, the tool helps you understand your IP version, ISP, ASN, hostname, approximate location, browser information, and possible privacy leaks. This makes it useful for normal users, developers, website owners, remote workers, VPN users, and anyone who wants a quick IP address check without using technical commands.
Most users still see an IPv4 address, which looks like four sets of numbers separated by dots. If you search for what my IPv4 is, check IPv4, IPv4 checker, or IP check. This tool helps you identify the IPv4 address currently visible to websites. IPv4 is widely used by home routers, mobile networks, hosting providers, and business internet connections, so it remains one of the most important IP addresses to check.
NetsTool also checks IPv6 when your network supports it. IPv6 is the newer Internet address format and is often used by modern ISPs, mobile carriers, and cloud networks. Seeing both IPv4 and IPv6 on the same page helps you confirm whether your connection is dual-stack, whether your VPN is hiding both versions, and whether your real network address is exposed through IPv6 even when IPv4 looks protected.
A public IP address is the address visible on the Internet. Websites, apps, online services, and network tools can see this public address when your browser connects to them. This is the IP shown by a public IP checker, what is my IP address tool, or check IP tool. Your public IP can belong to your home internet provider, mobile carrier, office network, hosting server, proxy, or VPN service.
A private IP address is different. It is used inside your local network by your phone, laptop, router, printer, or smart device. Private IPs usually look like 192.168.x.x, 10. x.x.x, or 172.16.x.x, and are not directly visible to normal websites. Knowing the difference matters because your public IP helps identify your internet connection, while your private IP helps devices communicate inside your home or office network.
Your IP address can reveal your approximate country, region, city, internet service provider, ASN, hostname, time zone, and network type. It does not show your exact home address, personal name, phone number, or private files, but it can still give websites a general idea of where your connection comes from. This is why IP location checkers and IP address lookup tools are useful for testing location accuracy.
NetsTool gives a wider view of your connection by showing IP location, ISP, ASN, hostname, browser details, user agent, device-related request data, and privacy signals where available. These details help you understand what your browser and network are sharing. If your result shows an unexpected city, country, ISP, proxy, or VPN provider, it may mean your traffic is being routed through another network.
To check if your VPN is working, connect to your VPN and refresh the IP checker. Your public IP address, country, ISP, and location should change from your real internet provider to the VPN server’s details. If the tool still shows your original ISP or real country, your VPN may not be connected correctly, or your browser may be leaking network information.
A good VPN check should also look beyond the main IP address. NetsTool helps users review IPv4, IPv6, DNS leak, WebRTC leak, proxy, and browser network signals, where available. This is important because some VPNs hide your IPv4 address but still expose IPv6, DNS requests, or WebRTC data. If your IP, DNS, and WebRTC results all match your VPN location, your privacy setup is much stronger.
Your IP address can change because most internet providers use dynamic IP addresses. A dynamic IP may update when your router restarts, your mobile network changes towers, your ISP renews the connection, or you switch from WiFi to mobile data. This is normal and does not always mean something is wrong with your internet connection.
Your IP can also change when you use a VPN, proxy, corporate network, public WiFi, or hosting environment. If you check my IP address today and see a different result tomorrow, the change may come from your ISP or from the network you are using. NetsTool makes it easy to compare your current IP, IP version, ISP, ASN, and location whenever your connection changes.
People use an IP checker for many practical reasons. You may need to check your IP before setting up a firewall rule, allowing access to a server, testing a VPN, fixing email or DNS issues, checking website security logs, confirming remote work access, or sharing your public IP with a hosting provider. A fast IP address check saves time because it shows the active network address immediately.
Website owners, developers, SEO users, and system admins often check IP details while testing hosting, CDN routing, DNS propagation, SSL setup, analytics filters, spam protection, login security, and server access. Normal users check IP information to confirm their location, see whether a VPN is active, or understand what websites can see. NetsTool is built for both simple users and technical users, so the result is clear but still detailed.
