Question 1

How accurate is IP geolocation?

Accepted Answer

IP geolocation is generally accurate at the country level (typically 95%+) and reasonably accurate at the region or city level for residential and broadband IPs. Street-level accuracy is not possible from an IP alone — the location returned is the network’s registration or routing location, not the user’s physical address. Mobile, satellite, VPN, and large carrier IPs can map to a city far from the actual user.

Question 2

What data sources power the lookup?

Accepted Answer

Results combine public regional internet registry (RIR) data — ARIN, RIPE, APNIC, LACNIC, and AFRINIC — for ASN, network range and registration information, with geolocation databases that map IP ranges to country, region, city, postal code and coordinates. Reverse DNS is resolved live against the authoritative PTR records for each address.

Question 3

What is an ASN?

Accepted Answer

An ASN (Autonomous System Number) is a unique number assigned to each independent network on the internet — typically an ISP, hosting provider, cloud provider, or large organization. The ASN identifies who owns and routes a given IP range. Each lookup shows the ASN, the organization that operates it, and the network range the IP belongs to.

Question 4

What is reverse DNS (PTR)?

Accepted Answer

Reverse DNS maps an IP address back to a hostname using a PTR record in the in-addr.arpa (IPv4) or ip6.arpa (IPv6) zone. It is the inverse of a normal A or AAAA lookup. Reverse DNS is often used to identify the operator of an IP — for example, an IP owned by Google may resolve to a hostname like crawl-66-249-66-1.googlebot.com. Not every IP has a PTR record configured.

Question 5

Can I look up a hostname or domain instead of an IP?

Accepted Answer

Yes. The lookup accepts IPv4 addresses, IPv6 addresses, and hostnames or domain names. When you enter a hostname, it is resolved to its current IP address and the full geolocation, ASN, ISP, and reverse DNS details are returned for that IP.

Question 6

Is the IP lookup free to use?

Accepted Answer

Yes, the web lookup is free for personal and professional use, with no sign-up required. A JSON API is also available for developers who want to integrate the same data into their own applications.
