Frequently Asked Questions
Answers to common questions about IP addresses, privacy, VPN/proxy detection, location accuracy and the subnet calculator on Show-IP.ir.
1. What is my IP address, and how does this site show it?
An IP address is a unique numeric identifier assigned to your device by your internet service provider (ISP). Show-IP.ir displays the public IP address your device is using to connect to the internet, along with its country, city, ISP and an approximate location on the map.
2. Is showing my IP address and location a privacy risk?
No. Every website you visit already sees this same public IP address — it isn't secret information. The location shown is only approximate, at city level, and does not reveal your exact home address. Show-IP.ir does not store any of your information.
3. Why does the city or location shown not match my real location?
Location is estimated from your ISP's IP address database, not from GPS. On mobile networks and with some ISPs, an IP address may be registered to a regional hub or a different city, so a difference of a few kilometers — or even a different city — is normal.
4. How does VPN, proxy and Tor detection work?
The "Security Check" section shows whether your IP address belongs to the Tor network, a proxy, a datacenter/VPN, or a known blocklist. This is useful for checking connection anonymity and spotting suspicious traffic.
5. What does the subnet calculator do?
Enter an IPv4 address and a subnet mask or CIDR (like /24) to instantly calculate the network address, broadcast address, first and last usable host, total address count, and usable host count. A handy tool for network admins and students.
6. Is Show-IP.ir free to use?
Yes, every feature on this site — IP lookup, network information, the security check and the subnet calculator — is completely free, with no sign-up required.
7. How does the map work, and is my precise location stored anywhere?
By default the page shows an interactive OpenStreetMap map. Your browser loads the map tiles directly from OpenStreetMap, so their servers see your browser's IP address and the map area being viewed, like any website you visit; if the online map can't load, a built-in static world map is shown instead. The "Use my precise location" button uses your browser's geolocation with your permission; those coordinates are only shown on the map in your browser and are never sent to this site's server.
8. Why is the IP address shown here different from the one in my router or phone settings?
Your phone or computer has a private address (like 192.168.1.20) that only exists inside your home network. This page shows your public address — the one the internet sees. If your router's WAN address differs from it too, your provider is probably sharing one public address between many customers (CGNAT).
9. Can someone find my exact home address from my IP address?
No. An IP address can narrow things down to a country or, at best, an approximate city, and that estimate is often wrong. Only your internet provider knows which subscriber used an address at a given time, and they normally disclose it only to authorities through a legal process.
10. Why does my IP address keep changing?
Most home and mobile connections get a dynamic IP address that the provider can change when the router restarts, the lease expires or you switch networks. If you need an address that never changes, ask your provider for a static (public) IP.
11. How can I change my IP address?
The quickest ways are restarting your modem or router, switching to another network such as a mobile hotspot, toggling airplane mode on mobile data, or using a VPN, proxy or Tor. After the change, reload this page and check that the IP, country and ISP are different.
12. How do I check that my VPN is working?
Open this page with the VPN off and note the IP, country and ISP, then connect the VPN and reload. All three should change, and the security section will usually flag the address as a VPN or datacenter. It is also worth testing for DNS and WebRTC leaks.
13. What is the difference between IPv4 and IPv6?
IPv4 addresses are 32-bit numbers like 203.0.113.5 and there are only about 4.3 billion of them, which is why they ran out. IPv6 addresses are 128-bit and written in hexadecimal, giving a practically unlimited supply. Many networks use both at the same time.
14. Can I get my IP address from the command line?
Yes. Run curl show-ip.ir (or curl show-ip.ir/ip) in a terminal or script and the site replies with just your public IP address as plain text, with no HTML.
