IP address basics
Start here if you want plain-English answers about public IPs, private IPs, IPv4, IPv6, and ISP assignment.
In-depth guides about IP addresses, privacy, networking, VPNs, browser exposure, location accuracy, and internet security.

IP address tools can answer simple questions quickly, but the underlying topics are easy to mix up. Your public IP, private IP, ISP, ASN, hostname, approximate location, DNS resolver, browser fingerprint, and user-agent are different signals.
This section groups the background guides so you can learn why a result appears, what it does and does not reveal, and which privacy or troubleshooting step to take next.
Start here if you want plain-English answers about public IPs, private IPs, IPv4, IPv6, and ISP assignment.
Use these guides when you want to know what your IP reveals and how to reduce exposure.
Use these when the result looks wrong, your VPN is unclear, or your connection behaves unexpectedly.
Everything you need to know about IP addresses, how they work, and why they matter for privacy.
TechnicalThe key differences between IPv4 and IPv6, and why the internet is transitioning to the newer protocol.
NetworkingUnderstand static and dynamic IP addresses, how ISPs assign them, and which type you have.
SecurityThe realistic risks of exposing your IP address and the steps that reduce tracking and abuse.
How-ToStep-by-step methods to change your IP address using a VPN, proxy, mobile network, or router reset.
GeolocationWhy IP lookup tools can show the wrong city, region, or ISP routing point.
BasicsLearn the difference between the address websites see and the address used inside your home network.
TechnicalA practical guide to IPv4, IPv6, dual-stack connections, and what users should check.
If you are troubleshooting a specific connection, start with the tool result first, then read the relevant guide. For example, if your location is wrong, compare the city, ISP, and VPN status before assuming a device problem. If your VPN is connected but your ISP still appears, run DNS and WebRTC leak checks next.
If you are learning from scratch, start with IP address basics, then move into privacy and tracking. That order makes it easier to understand what a VPN can hide, what it cannot hide, and why browser-level signals still matter.
