In today’s connected world, an IP address plays a vital role in how devices communicate over the internet. Understanding what an IP address is and how it works can help you improve your online security and fully leverage Nstproxy’s services for web scraping, automation, and more.
What Does an IP Address Do?
Think of your home address that lets delivery services find you — an IP address works the same way for your device on the internet. It’s a unique identifier assigned to every connected device, allowing data to be sent to and received from the correct destination.
An IP address stands for Internet Protocol address, and is typically assigned by your Internet Service Provider (ISP) so the network knows where to route your traffic.
How Are IP Addresses Distributed?
The allocation follows a global hierarchy:
- IANA (Internet Assigned Numbers Authority) distributes large IP blocks to regional registries.
- Regional registries assign smaller ranges to ISPs.
- ISPs allocate individual IPs to end users and devices.
Example: 203.0.113.220 is a typical IPv4 address format.
IP Addresses and Domain Names
While machines use IP addresses, humans prefer memorable names like nstproxy.com. This is where the Domain Name System (DNS) comes in — it translates domain names into IP addresses behind the scenes.
DNS servers (often run by your ISP) handle this process quickly and are usually located nearby to optimize speed.
IPv4 vs. IPv6 — The Two Main Protocols
- IPv4 – Introduced in the 1980s, uses 32-bit numbers, supports ~4.3B addresses. Currently running out due to device growth.
