IPRoyal sells rotating residential proxies and static ISP proxies. The rotating product is a shared pool billed by traffic. The ISP product is a dedicated residential-origin address that stays put. Both products use the large-market country set.
The fit is a buyer who wants rotating scale and a static household address from one vendor. Use rotating IPs for independent page fetches. Use ISP IPs for logins and for flows that break when the address changes. Do not expect the ISP product to behave like a mobile carrier exit.
Check consent and sourcing language on the residential pool. Check whether the ISP address is truly dedicated to your account. Confirm geo targeting depth. Measure both products on the same target if you plan to mix them. Keep datacenter IPs elsewhere if you still have a cheap crawl lane.
