Overseas proxy services usually come in two shapes: static residential IPs and rotating residential proxies (billed by traffic). They are not interchangeable — the billing model and the best-fit workloads are very different, and choosing the wrong one can significantly increase your cost.
Static residential IPs: billed per IP per month
A static residential plan gives you a fixed residential IP in a chosen country or city, billed monthly, with traffic normally unmetered. It fits workloads that need a stable, long-lived identity:
- Seller and payment dashboards for overseas marketplaces;
- Accounts that must stay bound to one IP;
- Low-traffic workloads where stability matters more than volume.
Pros: predictable cost and a stable IP. Cons: expensive for high traffic, and stock in popular cities is limited and often sold out.
Rotating residential proxies: billed per GB
Traffic-based plans charge for the data you actually use, and the IP can rotate per request or per session. They fit workloads that need many different IPs with small payloads:
- Ad delivery and creative verification;
- Price monitoring and SEO rank checks;
- Large volumes of short-session public data collection.
Pros: a large IP pool and pay-as-you-go pricing. Cons: downloading large files or streaming video through them is expensive.
Side-by-side comparison
| Aspect | Static residential IP | Rotating residential |
|---|---|---|
| Billing | Per IP × duration | Per GB of traffic |
| IP stability | Fixed | Rotating |
| Best for | Long-lived accounts, dashboards | Verification, monitoring, scraping |
| Cost profile | Predictable | Scales with usage |
Common combinations
Many teams use both: static residential IPs to keep core accounts logged in, and rotating residential traffic for bulk verification and collection. That keeps accounts stable without paying fixed IP fees for high-volume requests.
How to choose
- Decide whether you need a fixed IP or many different IPs.
- Estimate monthly traffic: above a certain volume, static IPs are cheaper.
- Check stock for your target country or city, and buy early for popular regions.
- Start with the smallest plan to verify access to your target sites, then scale up.
