# MiyaIP account and proxy concurrency FAQ

> Understand MiyaIP dynamic proxy device and connection rules, plan-specific limits, and how proxy concurrency differs from Crawler API task limits.

<AccordionGroup>
  <Accordion title="Is there a limit on the number of devices that can use an IP?">
    For traffic-billed **dynamic residential and mobile proxy plans**, the general rule is **no limits on concurrency or simultaneous connections**. Check your selected plan and current dashboard for its actual device, bandwidth, and connection conditions. Unlimited residential plans have their own package limits; this rule does not make those limits unlimited.

    See the [pricing FAQ](/faq/pricing) for traffic calculations or the [documentation guide](/introduction) to choose a product and setup method.
  </Accordion>

  <Accordion title="Do proxy concurrency rules also apply to Crawler API?">
    No. Proxy concurrency describes network connections; Crawler API concurrency describes tasks running at the same time. Do not apply the dynamic proxy's concurrency and simultaneous connection statement to Crawler API.

    Check your selected Crawler API plan and the current task concurrency limit in the dashboard. Schedule submissions and polling within those limits. See the [Crawler API tutorial](/developers/crawler-api) for setup.
