Question 1

Why is my IP location showing the wrong city?

Accepted Answer

IP geolocation is an estimate — it is not GPS. Your public IP address is assigned by your Internet Service Provider (ISP), and the location databases map that IP to the physical location of your ISP's nearest data center or routing hub, not your home address. If your ISP routes traffic through a regional hub in a different city, that city will appear as your location. VPNs, mobile data connections, and satellite internet can push this error even further. Geolocation accuracy is typically within 25–50 miles for most broadband connections.

Question 2

How do I find my router's public IP address?

Accepted Answer

Your router's public IP is the address the rest of the internet sees — not the 192.168.x.x address on your local network. The quickest way is to visit profilemyip.com: the IP shown at the top is your router's public IP. Alternatively, log into your router's admin panel (usually 192.168.1.1 or 192.168.0.1 in your browser) and look for a "WAN IP" or "Internet" status section. Note that if your ISP uses CGNAT (carrier-grade NAT), even your router's WAN IP may be a private address shared with other customers.

Question 3

What does my IP address reveal about me?

Accepted Answer

Your public IP address reveals your approximate location (usually city or region level, not a street address), your Internet Service Provider's name, whether you are on a residential, corporate, or mobile network, and sometimes the organization that owns the IP block. It does not reveal your name, physical home address, phone number, or email. Websites routinely log your IP with every request — ad networks and data brokers can correlate these logs to build behavioral profiles over time.

Question 4

Is it safe to share my public IP address with others?

Accepted Answer

Sharing your public IP address carries some risk but is generally not catastrophic on its own. Anyone with your IP can estimate your rough geolocation (city-level), attempt to scan for open ports on your router, or include your IP in targeted DDoS attacks. That said, most home routers have firewalls that block unsolicited incoming connections. The bigger risks are if you share your IP with someone malicious who then correlates it with other personal data. When in doubt, use a VPN to mask your real IP, and avoid sharing it unnecessarily in online games, forums, or with strangers.

Question 5

What is the difference between a static and dynamic IP address?

Accepted Answer

A static IP address is permanently assigned to a device or account — it never changes. Businesses and servers typically use static IPs because they need a consistent, reliable address that others can always reach. A dynamic IP address is temporarily assigned from a pool each time you connect and may change when you restart your router or after a lease period expires. Most home internet plans use dynamic IPs. There is also a middle ground called sticky dynamic — where your ISP tends to give you the same IP repeatedly but makes no guarantee.

Question 6

How often does my IP address change?

Accepted Answer

For most home broadband connections, your ISP assigns a dynamic IP via DHCP with a lease period of 24–72 hours. In practice, many ISPs silently renew the same IP as long as your router stays connected, so you may keep the same IP for weeks or months. To get a new IP, restart your modem and leave it powered off for a few minutes. Mobile data connections change IP more frequently — each reconnection typically gets a new address. Using a VPN gives you a different public IP from the VPN server immediately.

Question 7

How can I tell if my IP address is being tracked?

Accepted Answer

Every website you visit records your IP address in its server logs — this is standard practice and unavoidable without a VPN or proxy. Beyond basic logging, ad networks and data brokers build behavioral profiles tied to your IP. Signs that your IP may be actively tracked or flagged include: CAPTCHAs appearing unusually often, being blocked by websites without reason, or receiving targeted ads that seem suspiciously specific to your location. You can check if your IP appears on spam or abuse blacklists using our IP lookup tool. The most effective countermeasure is a reputable VPN, which substitutes the VPN server's IP for yours.

Question 8

What is a DNS leak and why does it matter?

Accepted Answer

A DNS leak happens when your device sends DNS queries — the requests that translate domain names like 'example.com' into IP addresses — outside your VPN tunnel, through your regular ISP instead. This defeats a major purpose of using a VPN: even if your traffic is encrypted, your ISP can still see every website you visit through your unencrypted DNS requests. You can check for leaks using the DNS Leak Test on this site. If you see your ISP's DNS servers in the results while connected to a VPN, you have a leak. Fixing it usually means enabling your VPN's built-in DNS leak protection or configuring your OS to use the VPN's DNS servers exclusively.

Question 9

How do I fix a DNS leak on Windows 11?

Accepted Answer

On Windows 11, DNS leaks often occur because the OS queries all available network adapters simultaneously (Smart Multi-Homed Name Resolution). To fix: open your VPN client's settings and enable its DNS leak protection feature. If your VPN doesn't have this option, go to Settings → Network & Internet → Advanced Network Settings → select your non-VPN adapter → Edit DNS → set it to a non-functional address (e.g. 0.0.0.0). After connecting to your VPN, re-run the DNS Leak Test to confirm all resolvers now belong to your VPN provider.

Question 10

How do I fix a DNS leak on iPhone (iOS)?

Accepted Answer

iOS occasionally bypasses VPN tunnels for DNS on Wi-Fi connections, especially with IKEv2-only VPNs. To fix: use a VPN app that implements the iOS Network Extension framework with DNS override (most reputable VPNs do). In your VPN app's settings, enable the DNS leak protection or 'force DNS through VPN' option. Alternatively, turn off Wi-Fi and use mobile data while connected to the VPN. After reconnecting, verify with the DNS Leak Test.

Question 11

Does using a VPN completely hide my identity online?

Accepted Answer

A VPN hides your real IP address and encrypts your traffic from your ISP, but it is not a complete anonymity solution. The VPN provider itself can see your traffic and real IP — so trust in the provider matters. Beyond IP, websites can still identify you via browser fingerprinting, cookies, logged-in accounts, and behavioral patterns. A VPN also does not prevent malware, phishing, or account-based tracking. For stronger anonymity, combine a VPN with a browser hardened for privacy (like Firefox with strict settings or Tor Browser), avoid logging into personal accounts, and regularly check your DNS and WebRTC leak status.

Question 12

What is WebRTC and can it leak my IP address?

Accepted Answer

WebRTC is a browser technology used for real-time communications like video calls and peer-to-peer file sharing. It uses STUN servers to discover your network path, which can expose your local network IP and sometimes your real public IP — even when you are connected to a VPN. This is called a WebRTC leak. You can check whether your browser is leaking via WebRTC using the Browser Fingerprint tool on this site. To prevent leaks, disable WebRTC in your browser settings, or use a browser extension that blocks WebRTC.

Question 13

What is browser fingerprinting and how is it different from cookies?

Accepted Answer

Browser fingerprinting identifies you by collecting technical details about your browser and device — canvas rendering, installed fonts, screen resolution, WebGL capabilities, audio processing characteristics, and more. Unlike cookies, fingerprinting leaves nothing on your device and cannot be cleared by deleting browser data. Each combination of these details creates a near-unique 'fingerprint' that can track you across websites even in private/incognito mode. You can check your own fingerprint uniqueness using the Browser Fingerprint tool on this site. Countermeasures include using the Tor Browser (which standardizes fingerprint values) or browser extensions like Privacy Badger.

Question 14

How do I hide my IP address for free?

Accepted Answer

The main free options are: Tor Browser (routes traffic through multiple relays, very high anonymity but slow), free VPN tiers (limited data/speed, and the free provider can see your traffic), and public web proxies (generally unencrypted, unreliable, and untrustworthy). Each option has significant tradeoffs. Tor Browser is the most private for web browsing. Free VPNs are best avoided unless from a reputable provider with a clear no-logs policy. For casual use, even a paid VPN costs only a few dollars per month and is far more reliable.

Question 15

What is the difference between HTTP and HTTPS headers?

Accepted Answer

With plain HTTP, all request and response headers travel unencrypted and are visible to your ISP, the network operator, and anyone on the same network. With HTTPS, the entire exchange — including headers like cookies, authorization tokens, and referrer information — is encrypted inside the TLS tunnel. Only the domain name (SNI) in the TLS handshake is visible to network observers before the tunnel is established. This is why HTTP sites leak login sessions and browsing details to your ISP, while HTTPS sites do not.

Question 16

How do I check if my SSL certificate is working correctly?

Accepted Answer

Use the SSL Check tool on this site: enter your domain and it will show the certificate issuer, expiry date, cipher suite, and whether HTTPS headers like HSTS are present. Key things to verify: the certificate is issued by a trusted CA, the expiry date is more than 30 days away, the Subject Alternative Names include your domain and www subdomain, and HSTS is enabled to prevent downgrade attacks. A padlock icon in the browser is a basic pass, but does not verify these finer details.
