What is an IP address?

An IP (Internet Protocol) address is a numerical label assigned to every device on a network. Public IP addresses are visible to websites and servers you connect to. IPv4 addresses have the format 192.168.1.1 (four groups of numbers); IPv6 addresses use hexadecimal groups separated by colons.

How accurate is IP geolocation?

IP geolocation is typically accurate to the country level and often to the city or region level. However, it can be inaccurate when users are behind VPNs, corporate proxies, or satellite internet. The coordinates shown are approximate — not GPS-level precision.

An Autonomous System Number (ASN) is a unique identifier assigned to each collection of IP networks managed by a single organisation (an ISP, company, or university). ASNs are used in BGP routing to identify which organisation "owns" a block of IP addresses.

Does this tool send my IP to jarvisbox?

No. Your browser fetches your public IP from api.ipify.org and then queries geolocation data from ipapi.co. Both requests go directly from your browser to those public APIs — jarvisbox does not receive or log your IP address.

Why does my location show a different city?

ISPs may assign IP blocks to a city that is different from your physical location. VPN, proxy, or Tor usage will show the VPN server's location rather than yours. Corporate networks may show the datacenter or headquarters location.

What is the difference between IPv4 and IPv6?

IPv4 (e.g. 203.0.113.1) uses 32-bit addresses and supports ~4.3 billion unique addresses, which are nearly exhausted. IPv6 (e.g. 2001:db8::1) uses 128-bit addresses, providing a virtually unlimited address space. Many networks now support both (dual-stack).

Can I look up any IP address, not just my own?

Yes. Enter any valid public IPv4 or IPv6 address in the input field and click Look Up. Private/internal addresses (192.168.x.x, 10.x.x.x, 172.16–31.x.x) will return limited information as they are not globally routable.

Carrier-Grade NAT (CGNAT) is used by ISPs to share a single public IP among multiple customers. Your public IP may be shared with many other users on the same connection, which is why IP geolocation for mobile networks often shows an ISP hub rather than your location.

IP info lookup

Look up geolocation, ISP, ASN, and timezone for your public IP or any IP address. Data fetched directly from your browser via public APIs.

Your browser queries ipify.org and ipapi.co directly. Your IP is not sent to jarvisbox.

How to use

Leave the input blank and click Look Up to see your own public IP details.
Or type any IPv4 or IPv6 address and click Look Up.
Results show country, region, city, ISP, ASN, timezone, and approximate coordinates.

Common use cases

Check your VPN — verify that your VPN is masking your real IP and location.
Investigate traffic — identify the ISP and country of an IP from server logs.
Debug geo-blocking — confirm what location a service sees for your connection.
Verify IP reputation — identify data center vs. residential IP ranges.
