Use our IP address lookup tool to instantly check your IP address and view detailed network information. This tool reveals your public IPv4 and IPv6 addresses, geographic location, Internet Service Provider (ISP), and other connection details. Whether you're troubleshooting network issues, verifying your VPN connection, or simply curious about what information your IP address reveals, our tool provides comprehensive data in real-time.
An IP address (Internet Protocol address) is a unique numerical identifier assigned to every device connected to a network. Think of it as your device's digital mailing address on the internet. When you check your IP address, you're viewing the identifier that allows other devices and servers to send data to your specific location on the network.
IP addresses serve two primary functions: host identification and location addressing. They enable devices to find and communicate with each other across local networks and the global internet. Every time you visit a website, send an email, or stream content, your IP address is how servers know where to send the requested information.
There are two versions of IP addresses in use today: IPv4 and IPv6.
IPv4 addresses consist of four numbers separated by periods (e.g., 192.168.1.1). Each number ranges from 0 to 255, providing approximately 4.3 billion possible addresses. IPv4 has been the standard since 1983, but the explosive growth of internet-connected devices has led to address exhaustion. When you check your IP address and see a format like "203.0.113.45", you're viewing an IPv4 address.
IPv6 addresses use a longer format with eight groups of hexadecimal numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). This format provides 340 undecillion possible addresses—enough to assign unique addresses to every device on Earth for the foreseeable future. IPv6 adoption is growing as ISPs and network operators transition from the limited IPv4 space. Many users now have both IPv4 and IPv6 addresses assigned simultaneously.
There are numerous practical reasons to perform an IP address lookup:
Your ISP is the company that provides your internet connection. The ISP owns blocks of IP addresses and assigns one to your connection. When you check your IP address, the ISP field shows which organization controls your IP address block. This information is public and stored in regional internet registry databases.
IP address location data shows the city, region, and country associated with your IP. This geolocation is determined by databases that map IP address ranges to physical locations. While generally accurate at the city or regional level, IP geolocation shouldn't be considered precise enough for exact street-level positioning. The location typically reflects where your ISP's network infrastructure is located, not your exact physical address.
An ASN is a unique identifier assigned to networks that exchange routing information on the internet. Large ISPs, cloud providers, and content delivery networks operate autonomous systems. The ASN helps identify which organization manages the network infrastructure routing your traffic. This information is particularly useful for network administrators performing troubleshooting or security analysis.
Your user agent string reveals information about your browser, operating system, and device type. Websites use this data to optimize content delivery and ensure compatibility. The user agent is transmitted with every web request and provides technical details that help developers debug issues and tailor experiences for different platforms.
When you visit this IP lookup tool, your browser sends a request to our server. This request automatically includes your IP address in the packet headers—it's impossible to communicate over the internet without revealing your IP address, as servers need to know where to send responses. Our tool simply reads this header information and looks up the associated details in geolocation and network databases.
The process happens in milliseconds: your browser connects, our server identifies your IP from the connection headers, queries authoritative databases for network and location information, and returns the complete dataset to display in your browser. No tracking or data storage occurs—the lookup is performed in real-time and the results are shown only to you.
Your IP address reveals certain information about your location and network provider, but it does not expose your personal identity, exact street address, or browsing history. However, IP addresses can be logged by websites you visit and potentially used to correlate activity over time.
If privacy is a concern, consider using a VPN (Virtual Private Network) or proxy server. These tools route your traffic through their servers, masking your real IP address and making it appear as though your connection originates from a different location. After connecting to a VPN, use this IP address lookup tool to verify your real IP is hidden and the VPN location is displayed instead.
Most residential internet connections use dynamic IP addresses that change periodically. Your ISP assigns you an IP from their available pool, and this address may change when you restart your modem or after a certain time period. Dynamic addressing is more efficient for ISPs as they can reuse addresses across their customer base.
Static IP addresses remain constant and are typically used for servers, business connections, or specialized applications requiring a permanent address. Static IPs usually require an additional fee from your ISP. You can determine if your IP is static by checking your IP address today, restarting your modem, and checking again—if it changes, you have a dynamic IP.
Your IP address reveals your approximate location (city/region) and ISP, but not your exact street address or personal identity. Law enforcement and ISPs can correlate IP addresses to customer accounts through legal processes, but average internet users cannot determine who you are based solely on your IP address.
If you have a dynamic IP address (most residential connections), your ISP may reassign you a different IP from their pool periodically. Changes typically occur when you restart your modem, after prolonged disconnection, or when your DHCP lease expires. This is normal behavior and doesn't indicate a problem with your connection.
The IP address shown by this tool is your public IP address—the one visible to the internet. Devices on your home network have private IP addresses (typically starting with 192.168, 10.0, or 172.16) that are only used for communication within your local network. Your router performs Network Address Translation (NAT) to allow multiple devices with private IPs to share a single public IP address.
Your IP address is transmitted to every website you visit, so it's not considered highly sensitive information. However, you should be cautious about posting your IP address publicly on forums or social media, as it could be used for targeted attacks, harassment, or correlation with other online activity. Think of it like a phone number—not secret, but not something to broadcast unnecessarily.
