Static vs Dynamic IP: What's the Difference?

A static IP stays the same; a dynamic IP can change whenever your ISP reassigns it. Most homes have dynamic IPs, which is part of why residential proxies rotate.

The short answer

  • Static IP: permanently assigned. Servers, businesses and ISP proxies use them.
  • Dynamic IP: handed out by your ISP and can change after a router restart, a lease expiry, or at the ISP's whim. Most home and mobile connections are dynamic.

Why it matters

Because home IPs naturally change, websites are used to seeing a household on a new IP, which helps rotating residential proxies blend in. If you need the same IP for weeks, for an account or allowlist, buy a static ISP or dedicated proxy.
