What is IP Address Lookup?

IP Address Lookup is a free online tool that reports detailed information about an IP address, including reverse DNS hostname, organization, ASN and IP whois. It supports both IPv4 and IPv6 address types.

It is also able to find the geolocation of an IP address and show its location on the map. Geolocation includes continent, country, region and city as well as the geographical coordinates (latitude and longitude).

The tool also represents the IP address in different formats: as IPv4, in decimal format and as compressed IPv6.

What is Reverse DNS?

Reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address. The Reverse DNS Hostname is resolved by querying the DNS server for a pointer (PTR) record. Often used in anti-spam filters.

What is IP Geolocation?

IP-based geolocation is the process of identifying the geographical location of an internet-connected device by its IP address. For better accuracy, we use several IP geolocation databases (IP2Location LITE, DB-IP Lite and MaxMind GeoLite2) and choose the most appropriate result.

What is an IP whois?

WHOIS is a public directory where you can look up "who is" responsible for a domain or IP address. The IP address whois response shows which organization is holding which IP address blocks and their details.

What is an Autonomous System (AS)?

Autonomous System (AS) is a large network or multiple networks with a single routing policy. Basically, it is a collection of IP routing prefixes that allow Internet connected systems to communicate with each other.

What is an ASN?

In order for multiple autonomous systems to interact, each needs to have a unique identifier. An autonomous system number (ASN) is such a unique number used to identify a network on the Internet. AS numbers are assigned in blocks by Internet Assigned Numbers Authority (IANA). As of December 2020, the number of allocated ASNs exceeded 99,000.

What is a BGP prefix?

A BGP prefix is a network address written in CIDR notation (IP address followed by a slash and the bit-length of the subnet mask, for example:, which is advertised via Border Gateway protocol (BGP) and is associated with specific BGP attributes including origin, AS-Path and other information. The primary function of BGP protocol is to exchange routing and reachability information among autonomous systems (AS) on the Internet.

What is a NOC?

NOC stands for Network Operations Center and it is one or more locations from which technicians perform network monitoring or network management tasks.
