Frequently Asked Questions
What is an IP address?
An IP (Internet Protocol) address is a unique identifier assigned to every device connected to a network. It allows devices to communicate with each other over the internet.
How accurate is IP geolocation?
IP geolocation typically provides city-level accuracy, but several factors affect precision:
- Mobile data connections may show the carrier's headquarters location
- VPNs and proxies will display the exit node location
- ISP routing configurations can sometimes provide misleading data
For most users, country-level identification is highly accurate, while city-level data may be approximate.
Why should I check for VPN leaks?
VPN leaks can expose your real IP address and location, compromising your privacy.

CIDR (Classless Inter-Domain Routing) notation is a compact representation of an IP address and its associated routing prefix (e.g., 192.168.1.0/24).

What is Base64 encoding used for?
Base64 is commonly used to encode binary data (like images or files) into ASCII characters for safe transmission over text-based protocols like email or URLs.
