Network ranges for US
US Network Ranges A Lawless Frontier
These aren’t every single range in the US, but if you know about IP addressing and CIDR, and IP geographic location then some of this will probably make sense to you. Analyze traffic, detect threats and fine-tune your network using the above tools and resources.
Why Trouble With Defining Ranges in US Networks
Here are some complications which make defining US network ranges hard:
- Dynamic IP Allocation: A lot of ISPs dynamically set up your IPs for consumers. This very fact implies that an IP address constantly changes, and a static list is never going to work.
- Private IP Addresses: Most of the IP addresses are private and not on the public internet. These are utilized in private networks such as home networks and corporate intranets.
- Never Ending Growth: The number of internet linked devices is not decreasing, hence need for IP addresses are high.
- Conservation of IP Addresses: Due to IPv4 address exhaustion concerns, mapping methods like NAT help map many private IP addresses to one public address.
Where to Find Network Ranges
- While a comprehensive list of all the US network ranges does not exist, here are some links that may help to get your needs met:
IP Geolocation Databases:
- Really, these databases resolve IP addresses into geolocations — country, region and city.
- Some of the commonly used providers include MaxMind, IPInfoDB and IP2Location.
Whois Lookup:
- It lets you query info regarding a domain name or IP address. It will provide you with the owning organization of an IP address range.
Network Scanners:
- The available network scanning tools can be used to scan a network in order to detect active IP addresses and determine their connected devices.
Internet Registries:
- Regional Internet Registries (RIR) such as ARIN (American Registry for Internet Numbers) assign IP addresses to organizations in North America. They maintain large databases containing information on big CIDR allocations by IP address.
IP Address Ranges
- An IP address is normally expressed in CIDR (Classless Inter-Domain Routing), known as a network address and prefix length. The available IP addresses in the range is defined by the prefix length. A network includes 256 IP addresses such as 192.168.1.0 to 192.168.1.255 for example is 192.168.1.0/24
Information of Network ranges for US
Why network ranges are important to understand:
- Network Security: If you know who or where the network traffic is originating from, it becomes easier for you to identify and prevent security threats.
- For Network Admins:- As a network administrator, you can use range information to tune your network and find faults.
- Digital Marketing: IP address ranges are often closely related with geographic locations hence making targeted based advertising and content delivery.
- Fraud Prevention: The patterns of your traffic on the network can help you eliminate cases of fraud.
Conclusion
These aren’t every single range in the US, but if you know about IP addressing and CIDR, and IP geographic location then some of this will probably make sense to you. Analyze traffic, detect threats and fine-tune your network using the above tools and resources.
