US IP Blocks
US IP Blocks
IP Block: A block of Internet Protocol addresses assigned to an organization. It offers a protocol for IP network allocation and controls the flow of traffic.
What is an IP Block and Why are IP Blocks Important?
IP blocks are used in:
- Network Security: To obtain traffic origin and deny malicious activity
- Geolocation: IPs blocks, therefore, allow websites and services to identify where a user is from, allowing them to personalize ads or content delivery and language localization.
- Network Management: Network Administrators use IP blocks to route network traffic, troubleshoot issues and enforce security.
As a technological giant, the U.S. has an outsized number of IP blocks assigned to various parties including:
- Internet Service Providers (ISPs): Massive IP blocks are given to ISPs such as Comcast, Verizon, AT&T and Spectrum before they are distributed among their clients.
- Corporate Networks ‐ big companies and institutions have their own internal IP blocks.
- IP block are used by Federal and state government agencies for their intranets and other external services.
- Educational institutions: Virtual classrooms and for any university, college or school with an input practice of blocks which can go online for learning or research.
How to Find US IP Blocks
There is no definitive list of US IP block, but you could use:
- IP Address Databases – Websites such as IPinfo and IP2Location contain extensive details regarding IP address locations and relevant network identification.
- Whos is search tool: You can use whos is to get Owner information of IP address or ip block.
- Through network scanning: find out devices and IP block with tools like Nmap that network administrators use.
Under US IP Block You’d Think Or Challenges In Finding
- Dynamic IP Addresses: Dynamic IP addresses are used by many home users and small businesses. Which makes locating certain range of IP block very tough.
- Private IP Address These are for private network use only. They are non-routable addresses that your private network cannot connect to the outside internet.

Future of IP Addressing
The demand for IP addresses is rising as the Internet expands. The world is moving to IPv6, a new version of the IP protocol with a vast address space as a solution. This means a lot of devices share unique identifiers, but also make it easier to find them on the internet (Which is replaced by IPv6 over time as IPv4 available addresses are exhausted).
