Question 1

What information does an IP lookup reveal?

Accepted Answer

An IP lookup returns the approximate geographic location (city, region, country), the ISP or organization that owns the IP range, the timezone, approximate latitude/longitude, and sometimes the postal code. It does not reveal the physical street address, device type, or the identity of the person using the IP. The data comes from regional internet registries and ISP allocation databases.

Question 2

How accurate is IP geolocation?

Accepted Answer

IP geolocation is typically accurate to the country level (99%+), fairly accurate to the region or state level (80–90%), and only moderately accurate to the city level (50–80%). It can be significantly off if the user is on a VPN, proxy, or Tor network, since the visible IP belongs to the exit node, not the user's actual location. Corporate networks often route through a central office IP.

Question 3

What is the difference between a public and private IP address?

Accepted Answer

A public IP address is globally routable on the internet and uniquely identifies a device or network to the outside world. A private IP address (10.x.x.x, 172.16–31.x.x, 192.168.x.x) is used within local networks and is not reachable from the internet directly. Your home router has one public IP shared by all devices, which each have their own private IP on the local network.

Question 4

What is the difference between IPv4 and IPv6?

Accepted Answer

IPv4 uses 32-bit addresses written as four decimal groups (e.g. 192.168.1.1), providing about 4.3 billion unique addresses. IPv6 uses 128-bit addresses in hexadecimal (e.g. 2001:db8::1), providing a virtually unlimited address space. IPv4 exhaustion led to NAT (sharing one public IP across many devices), which IPv6 eliminates. This tool supports lookups for both formats.

Field	What it shows	Use case
IP address	Your public-facing network address	Identify yourself on the internet; verify VPN/proxy
City / Region	Geographic location of the IP registration	Content localization, fraud detection, analytics
Country	Country where the IP block is registered	Geo-blocking, compliance (GDPR regions), routing
ISP / Org	Internet Service Provider or organization owning the IP range	Identify cloud/CDN provider, ISP throttling checks
Timezone	Timezone associated with the IP location	Default timezone for new users, scheduling
Latitude / Longitude	Approximate coordinates of the IP registration	Map display, distance calculations (approximate)
Postal code	Postal code of the registered IP location	Regional pricing, shipping estimates
