IPv4 address and proxy port: reading connection details
Proxy details are often displayed as one line, which makes an address, port, username, and password look like one value. In reality, the IPv4 address identifies a network node, the port selects a service on that node, the protocol defines the exchange, and credentials grant access.
Key points in one minute
- An IP address and port form a network endpoint.
- One IP address can serve many independent ports.
- The proxy port is not the destination website's port.
- Protocol and authorization should remain separate fields.
What IPv4 identifies
An IPv4 address is written as four decimal groups. For a proxy user, it identifies the server the application connects to first. It does not contain a port, credentials, or information about the request destination.
The role of the port
A transport port lets several services share one IP address. A service may provide separate HTTP and SOCKS5 ports or determine the protocol another way. Copy the numeric value exactly, without added spaces or punctuation.
Why the scheme matters
A string without a scheme can be ambiguous: one application assumes HTTP while another asks for the type separately. A complete URI helps the client choose how to talk to the proxy, although reserved characters in credentials require correct encoding.
Validate before bulk import
Map the application's fields to address, port, protocol, username, and password. Import one test record and access an approved control resource first. Proceed with a bulk import only after that record succeeds.
Practical checklist
- 1Check all four groups of the IPv4 address.
- 2Copy the port into a numeric field without extra characters.
- 3Select HTTP or SOCKS5 explicitly.
- 4Do not confuse a username with a server name.
- 5Validate one record before a bulk import.
