IP Address 101: How Do IP Addresses Work?

By CoExistWP

Here is a simple way to understand IP addresses and how IP address validation can work for you. An Internet Protocol address (IP address) is a numerical label attached to each device, as in a printer or computer that participated in a computer network using Internet Protocol for communication.

An Internet Protocol address serves two primary functions: host or network interface location addressing and identification. To its designers, it is a 32-bit number, and the Internet Assigned Numbers Authority (IANA) manages it’s space allocations worldwide. It delegates regional Internet registries (RIRs) to assign IP address blocks to local internet service providers.

IP addresses are assigned to a host either anew upon booting time or permanently through fixed configuration of its software or hardware. Using a “static Internet Protocol address” means persistent configuration. Using a “dynamic Internet Protocol address,” on the other hand, is assigning a computer’s address every so often.

A static IP address is manually assigned to a computer by an administrator, and there is a specific procedure for each platform. This is differently done in the case of dynamic IP addresses, which are assigned by the computer interface or host software, or by a server using Dynamic Host Configuration Protocol or DHCP. These dynamic Internet Protocol addresses are most usually assigned on LANs and broadband networks by DHCP servers, and they rid the admin of the added task of assigning specific static addresses to every device on the network. They also allow numerous devices to share limited network address space if only a certain number of them will be online at once.

In the event that static or stateful address configurations fail or are not present, an operating system could assign an Internet Protocol address to a network interface through the use of stateless auto configuration methods.

You may also be frequently hearing about IP blocking and firewalls. Firewalls carry out the task of performing IP blocking to protect networks from prohibited or unauthorized access, and they are commonly used today. Either through using a blacklist or a whitelist, the blocked address is the perceived Internet Protocol address of the assignee. This means that if the client is making use of a proxy server or network address translation, Internet Protocol address blocking may result in individual computer blocking.

IP address validation services are widely available today to validate addresses through verifying and geotargeting website visitors to help prevent fraud. For instance, there is a validation service that is a programmable XML Web Service to allow businesses to integrate IP-based location information, distance calculation, and other geographic intelligence into Web-enabled applications and business processes.

This service does not only validate 192.168.0.1 , but also collect anonymous proxy data from 165,000 computers, which are scattered across the world and acting as listening posts. These computers provide insight to other computers that are participating in malicious behavior.
