Every link you open from a farmed list goes out through your own device's connection -- Black Wire itself can't route that traffic for you. If you want every signup in a list to come from the same consistent IP, and a fresh one for the next list, you need a sticky-session proxy configured on your own browser or machine. Here's the setup.
A "rotating" proxy hands you a new IP on every single request -- great for scraping, bad for signups, since most sites flag an account that gets created and immediately looks like it's bouncing between IPs mid-session. A sticky session holds one IP for as long as you tell it to (minutes to 24h+), so a whole list run looks consistent, then you rotate to a clean IP before the next batch.
Any proxy service offering "sticky sessions" works. Common choices: IPRoyal, Webshare, Smartproxy, Bright Data. Residential IPs blend in better than datacenter IPs for most signup flows, at a higher cost per GB -- your call based on budget and how picky the target sites are about IP reputation.
Your provider gives you a proxy endpoint (host + port) and credentials that usually include a session-ID baked into the username, e.g. user-session-abc123:password. As long as that session ID stays the same, you keep the same IP. Change the session ID (or wait for it to expire), you get a new one.
Easiest route: install a proxy-switcher extension like FoxyProxy (Chrome/Firefox). Add your provider's host/port/credentials as a proxy profile, then toggle it on before you start farming a list. Alternative: set it system-wide in your OS network settings, but that routes everything through the proxy, not just this one browser -- the extension route is cleaner.
With the proxy active, work through the list in Black Wire as normal -- every "Go to Site" click now goes out through that one sticky IP for the whole run.
When you hit "Start New List," change your proxy session ID (most providers let you just edit the username string, or hit a rotate button/endpoint in their dashboard) before you begin the next batch. New session ID = new IP.
