What is an IP address?

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing.

What Can You Learn from an IP Lookup?

Every device connected to the internet has a unique IP (Internet Protocol) address. Looking up an IP address can reveal valuable information for troubleshooting and security analysis:

Geolocation: Identify the approximate physical location of the server or device (country, region, and city).
ISP and Organization: See which Internet Service Provider or organization owns and manages the IP address.
ASN (Autonomous System Number): Understand the larger network block to which the IP address belongs, which is useful for identifying the source of network traffic.

This information is crucial for identifying the source of emails, tracking down malicious activity, or simply understanding more about your own network's public footprint.

What is an ASN (Autonomous System Number)?

An Autonomous System Number (ASN) is a unique number assigned to an Autonomous System (AS), which is a large network or group of networks that has a single common routing policy. Looking up an ASN can tell you which major organization (like an ISP, university, or large company) controls a given IP address.

Why would I need to look up an IP address?

You might look up an IP address to identify the source of suspicious email or network traffic, determine the geographic location of a visitor or server, or learn more about the network provider that owns the IP address.
