Find answers to common questions about IP addresses and network tools

An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network. It serves as an identifier for your device and allows it to communicate with other devices on the internet.
IPv4 uses 32-bit addresses (e.g., 192.168.1.1) and can support about 4.3 billion unique addresses. IPv6 uses 128-bit addresses (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334) and can support a virtually unlimited number of unique addresses. IPv6 was created to address the shortage of IPv4 addresses.
Most internet service providers assign dynamic IP addresses that can change periodically. This happens when you restart your router, reconnect to your network, or when your ISP's DHCP lease expires. If you need a consistent IP address, you can request a static IP from your ISP.
An IP address can provide approximate location information, typically at the city or region level. However, it cannot pinpoint your exact physical address. The geolocation data is based on your ISP's server locations and may not always be accurate.
A port checker helps you verify if a specific port on your network is open and accessible from the internet. This is useful for configuring servers, gaming, remote access, or troubleshooting network connectivity issues.
You can protect your IP address by using a VPN (Virtual Private Network), which routes your internet traffic through encrypted servers and masks your real IP address. We provide links to trusted VPN services on our homepage.
Your user agent string contains information about your browser, operating system, and device type. This information helps websites optimize their content and functionality for your specific setup.

Cloud console access is essential for managing security groups, firewall rules, and network configurations in cloud environments like AWS, Azure, and Google Cloud. Remote developers and gig workers often need to whitelist their ip-addresses to access resources in the cloud. Our quick links help you access these consoles faster when configuring IP-based access controls.
