r/ProxyUseCases

Had something happen recently that finally made this click for me

I was running a setup and everything looked fine at first… then in like 2 days of using proxies bunch of my IPs stopped working almost at the same time (this was really weird to me)

At first I thought:

• maybe the site tightened limits
• maybe something broke in my setup

But turns out most of those IPs were from the same subnet

From what I understand now:

If your proxies share the same first 3 octets (like 212.65.112.x), they’re likely in the same /24 subnet

And some sites don’t just block one IP, they block the whole range

which can be like 200 IPs gone at once

Makes sense when you think about it, but I honestly never paid attention to this before

Mobile/lte proxies with the option of tcp fingerprint alternation?

I built Trooper after hitting Claude's free tier limit mid-conversation one too many times.

It's a lightweight Go proxy that sits between your app and any LLM API (Claude, GPT, Groq, Mistral). When the primary provider hits a quota or rate limit, it automatically reroutes to a local Ollama model — full conversation context intact. Zero code changes in your app, just point your base URL at localhost:3000.

What it does:

• Works with any LLM provider, not just Claude
• Preserves full conversation history across the switch
• Streaming support
• Configurable fallback trigger codes (429, 402, 529, 400 by default)
• 401 errors surface properly — bad keys are never masked
• Single Go binary, Docker support

Tested this morning — mid-conversation context preserved perfectly across the switch. Built in an evening.

Happy to answer questions or take feedback

What's next: MCP integration with Claude AI

We need to talk about how normalized it is for proxy providers to wipe your unused gigabytes every 30 days. You are paying for phantom data to pad their margins. I did a cost analysis and migrated my entire operation to GonzoProxy strictly for their "Perpetual Traffic" model. You buy traffic at $2.0-$6.5/GB and it never expires. Plus, proxy generation is free via their RESTful API, so you can spin up thousands of endpoints without overhead. Check your provider's TOS—how much data did you forfeit last month?
