The ip address lookup is a unique numeric string identifier assigned to each device that connects to the Internet. It is used to identify computers, mobiles, tablets and any other machine that communicates using TCP/IP.
Your public IP address follows you wherever you go on the internet. It is used by websites to track your browsing history, email activity and other personal information about you.
A reverse ip lookup is an easy way to find all A records associated with a specific IP address. This is especially useful when identifying virtual hosts being served by web servers.
How Fake IP Addresses Can Harm Your Business and What You Can Do About It
The reverse IP lookup can be run against a single IP address, or across a CIDR network block. Free users are limited to a maximum of 500’000 results, while registered members can get up to 10 million.
Bing can perform a reverse ip lookup for any search query that resolves hostnames from an IP address. It is a great tool for detecting any fraudulent activity by a customer.
Reverse IP Lookup is also a good technique for locating vulnerabilities in a server. If a web server is oversubscribed and has many websites hosted on it, then performing a reverse IP lookup can help to pinpoint which sites are using which ip addresses.
Private IPs (sometimes called LAN IPs) are used to connect a computer, mobile or tablet to the local network without exposing it to the public internet. They can be dynamic or static depending on how the router is configured.
