What the proxy changes
A residential proxy routes a request through an IP address assigned to a household connection. The website receives the request from that exit IP rather than directly from your connection. It still decides whether to allow the request.
That distinction matters. A proxy changes the network route; it does not give you permission to access a site, remove its rate limits, or guarantee that an account will be accepted.
Use rotation for independent requests
With a rotating session, later requests can use different exit IPs. It can suit separate, permitted checks where each request stands on its own, such as checking public pages of a site you operate from more than one location.
Rotation is awkward for a multi-step workflow. If a site expects one session to stay on one connection, an IP change partway through can interrupt your test. Use a sticky session when continuity matters.
Use a sticky session for a sequence
A sticky session asks the gateway to keep the same exit IP while you complete a sequence of requests. On NumberHub, the login supports a -sid- suffix for that purpose. It is a session setting, not ownership of a permanent IP.
Keep the same session identifier for the steps that belong together. Start a new one when the next task is independent. If the connection ends or the available pool changes, check the exit IP again before assuming it stayed the same.
Check the country and your usage
NumberHub also supports a -country-xx login suffix for country targeting. Check the current locations before buying: a country page is not a stock guarantee. Choosing a country does not guarantee that another website will accept your connection or registration.
Packages are prepaid by data amount and last up to 30 days from purchase, or until the data is used. The same login supports HTTP and SOCKS5. Keep the password out of source code and logs, and watch usage on the order page.
