- What Is a VPN Leak? VPN & Privacy Understand IP, DNS, IPv6 and WebRTC leaks and how to test a VPN correctly.
- What Is a DNS Leak? VPN & Privacy How DNS requests can bypass a VPN, why resolver identity is not the route, and how to test correctly.
- What Is a WebRTC Leak? VPN & Privacy How ICE candidates expose network addresses, why candidate type is not a verdict, and how to test correctly.
- What Is an IPv6 Leak? VPN & Privacy How IPv6 bypasses a VPN on a dual-stack host, why an IPv6 address is not a verdict, and how to check the route.
- Why Is My IP Address Showing the Wrong Location? IP Addresses How ISP address pools, CGNAT, mobile networks, VPNs and geolocation databases decide the city an IP maps to.
- IP Geolocation IP Addresses How IP geolocation is built, why databases disagree, how to read an accuracy radius, and what a public IP can really reveal.
- What Is an IP Address? IP Addresses IPv4, IPv6, public vs private, NAT and CGNAT, routing, and what your IP actually reveals.
- IP Lookup Explained IP Addresses How to read prefix, ASN, BGP, RPKI, RDAP, reverse DNS and geolocation as separate evidence layers.
- Public vs Private IP Address IP Addresses What makes an address public or private, how NAT and CGNAT connect them, and why neither one means what people assume.
- Static vs Dynamic IP Address IP Addresses What keeps an address stable, what can make it change, and how that interacts with DHCP, CGNAT, DDNS and IPv6.
What these guides cover
VPN & Privacy
VPN leaks, kill switches, split tunnelling and how privacy tests actually work.
IP Addresses
Public and private addressing, IPv4 vs IPv6, CGNAT, ASNs and what an IP can reveal.
DNS & Internet
Resolvers, reverse DNS, PTR records and encrypted DNS over HTTPS and TLS.
Subnetting & Routing
Subnet masks, CIDR, VLSM, route summarisation and prefix edge cases.

- VPN Leak Test Compare HTTP, IPv4/IPv6, WebRTC and DNS paths for a conservative multi-signal result. →
- DNS Leak Test See which DNS resolvers answered a query made from your browser. →
- WebRTC Leak Test Check for a public address exposed through WebRTC / ICE. →
- IP Lookup Registration, BGP routing, origin ASN, reverse DNS and RPKI for any address. →
Every guide is reviewed against the same evidence standards used across IPRevealed.
