1. Introduction to Internet Protocol Architecture

In the vast expanse of the digital universe, the Internet Protocol (IP) serves as the fundamental addressing system that allows devices to communicate. At bycor.online, we believe that understanding this infrastructure is crucial for developers, cybersecurity analysts, and privacy-conscious individuals alike. Every packet of data traversing the web carries a source and destination IP address, acting much like the "From" and "To" addresses on a physical envelope.

The current internet operates primarily on two versions of this protocol: IPv4 and IPv6. IPv4, a 32-bit addressing scheme, allows for approximately 4.3 billion unique addresses. While this seemed sufficient in the 1980s, the explosion of IoT devices has led to address exhaustion. This necessitated the birth of IPv6, a 128-bit system capable of providing 3.4 x 10^38 addresses—an astronomical number ensuring that we will not run out of addresses for the foreseeable future.

2. The Science of Geolocation

How does a tool like bycor.online determine your physical location based solely on a string of numbers? The process is known as IP Geolocation. It involves mapping an IP address to a real-world geographic location. This is not done via GPS (which relies on satellite signals) but through complex databases maintained by Regional Internet Registries (RIRs) like ARIN (North America), RIPE NCC (Europe), and APNIC (Asia Pacific).

Internet Service Providers (ISPs) allocate blocks of IP addresses to specific regions. When data is mined from these allocations and cross-referenced with user-submitted data, Wi-Fi positioning systems, and network routing information, a geolocation database is formed. The accuracy varies: country-level accuracy is typically 95-99%, while city-level accuracy can range from 50% to 80% depending on the ISP's infrastructure.

3. Autonomous System Numbers (ASN) and Routing

The internet is effectively a "network of networks." These networks are organized into Autonomous Systems (AS). An AS is a collection of connected IP routing prefixes under the control of one or more network operators on behalf of a single administrative entity. Each AS is assigned a unique Autonomous System Number (ASN).

Our tool displays the ASN associated with an IP address, which reveals the administrative authority behind the connection. This is vital for cybersecurity professionals tracking malicious traffic. If an attack originates from a specific IP, knowing the ASN allows authorities to contact the specific ISP or hosting provider responsible for that network segment.

4. Privacy Implications and the "Open Web" Philosophy

At bycor.online, we advocate for transparency. Your IP address is a digital fingerprint. While it is necessary for routing traffic, it can also be used to track user behavior, enforce censorship, or target advertising. Understanding what information your IP reveals is the first step in digital self-defense.

Tools like VPNs (Virtual Private Networks) and Proxies mask this IP address, routing your traffic through a different server. Our tool is often used to verify that such privacy measures are working correctly. If you are connected to a VPN in Switzerland, but our tool shows your location as New York, your IP is leaking.
