What is a psiphonode (pN) ? What is a psiphonite (pI) ?

Things you should know

A psiphonode is a proxy server and censorship circumvention provider that is located in an uncensored country.

A psiphonite is a psiphon user living in a censored country. The psiphonite connects to a psiphonode (set up by someone they know and trust), to access information freely.

What is an IP address?

An IP identifies a specific computer or other network device on a network. It is analagous to a street address or a phone number.

What is an Internal IP?

An Internal IP is assigned to your computer if it is running from within a Local Area Network (LAN). This IP is not directly accessible from the Internet.

What is an External IP?

An external IP address is the unique identifier assigned to you by your Internet Service Provider (ISP). There are two types of external IP address, static and dynamic. Static is fixed and therefore never changes. Dynamic changes every time you connect to the Internet.

What is a Port?

A port is a special number present in the header of a data packet used to map data to a particular process running on a computer. Different processes run on different standard ports assigned by the Internet Assigned Numbers Authority (IANA). The default port for psiphon is 443, because of the “https” protocol. However, this can be customized.

What is a Router?

A router acts as a junction between two or more networks to transfer data packets.

What is a Firewall?

A firewall blocks packets or ports based on rules determined by the computer user. These rules can range from very general to very specific.

What is a Server?

A server is a host computer on a network that handles requests for data, email, file transfers, and other network services from other computers (ie, clients). In the context of psiphon, the psiphonode is the server.
