Overview
Every network connection has two endpoints: the local application and a remote network.
The Network Details panel displays publicly available information about the selected remote network, helping you better understand who owns and operates it.
Network Information
The following information may be available for the selected network. Some fields depend on publicly available registration data.
| Field | Description |
|---|---|
| Country | Geographical location of the registered network. |
| Network Name | Name associated with the network provider. |
| Organisation | Company or organisation responsible for operating the network. |
| Technical Contact | Technical contact information when available. |
| Abuse Contact | Contact for reporting spam, malware or other suspected misuse. |
Network Concepts
| Concept | Example | Description |
|---|---|---|
| Remote IPv4 | 142.250.74.78 |
Four decimal numbers separated by dots. The exact address used by the current connection. |
| Remote IPv6 | 2a00:1450:4001:82b::200e |
Longer hexadecimal address separated by colons. IPv6 is the modern Internet addressing standard. |
| Network Range | 142.250.64.0/19 |
Represents many related IP addresses belonging to the same network. |
| CIDR | /24 |
The number after the slash identifies how large the network is. It describes a network, not an individual IP address. |
Understanding CIDR
CIDR (Classless Inter-Domain Routing) is the standard way of describing network ranges.
For example:
| Notation | Meaning |
|---|---|
203.0.113.45 |
One individual IP address. |
203.0.113.0/24 |
A network containing 256 related IPv4 addresses. |
203.0.0.0/16 |
A much larger network containing many thousands of addresses. |
2001:db8::/48 |
An IPv6 network range. |
Whenever you see a slash (/) followed by a number, the value normally represents a network rather than a single host.
Understanding Responsibility
The organisation operating a network provides the infrastructure that carries the communication.
It does not necessarily own or control every application or service using that network.
When evaluating an unexpected connection, consider both the application that initiated it and the organisation operating the remote network.
Important — IP Address vs Network Range
A single IP address identifies one destination.
A network range represents many related addresses operated by the same organisation.
Blocking one IP affects only that address. Blocking a network range may affect many servers belonging to the same provider or service.
