The main difference is where your traffic comes from. Mobile proxies use a carrier’s network. Rotating residential proxies use home internet connections. Static residential, often called ISP proxies, commonly use consumer-ISP addresses on datacenter hardware.
Your choice comes down to the network, location and session your task needs. Pricing varies by product: some plans charge for data, others per IP or per month.
Mobile carriers often let many subscribers share one public IPv4 address. That saves scarce IPv4 addresses through a method called carrier-grade network address translation, or CGNAT.
Sharing isn’t exclusive to mobile networks. A 2018 study using 2014–2016 data found CGNAT in about 4,200 networks, many not classified as mobile. The carrier network is what distinguishes a mobile IP.
You’ll often hear that mobile IPs face fewer blocks because websites don’t want to cut off many real users at once. Don’t treat that as a guarantee. Cloudflare’s October 2025 research found CGNAT IPs were rate-limited three times more often than non-CGNAT IPs, despite a lower mean bot rate: 7% versus 13.1%.
That study compared CGNAT and non-CGNAT addresses, not commercial mobile and residential proxies. It shows why a shared IP doesn’t automatically avoid rate limits. Blocks and CAPTCHAs still depend on the website, carrier and request behavior, so test your target before paying more for mobile.
A rotating residential proxy uses an IP from a home internet connection. If that device goes offline, the IP may change. Mobile IPs can change too, when a device reconnects or the carrier resets its session.
A sticky session lets you reuse one IP for a while, provided it stays available. How long it lasts depends on the provider and product.
Need one address for longer? Look at static residential or ISP proxies. Those names often describe the same product: a consumer-ISP address running on datacenter hardware. It’s intended to stay assigned to you, subject to the provider’s terms and replacement events.
That combination also explains why a checker may show both ISP and hosting labels. They can describe different aspects of the same address.
Location options vary by provider. ASN means the network identifier; check which networks and locations are actually available on your plan.
| Area | Residential proxies | Mobile proxies |
|---|---|---|
| Network/IP source | Rotating: home internet connections. Static/ISP: consumer-ISP addresses commonly hosted on server hardware | IPs from mobile carriers (4G/5G), usually shared among many subscribers |
| Targeting | Usually broad: country, state/region, city, ZIP, ISP or ASN | Often country, carrier or ASN, sometimes region or city. City-level targeting may be less precise |
| Reputation caveats | Depends on how the IP was used before and whether it's shared. A residential label doesn't guarantee it won't be blocked | Sites may be reluctant to block shared carrier IPs, but shared IPs can still be rate-limited. Usually priced higher |
| Session behavior | Rotating plans offer IP changes and often sticky sessions. Static/ISP plans are intended to retain an address, subject to provider terms | Rotating and sticky sessions are common, but IPs may change more often as devices reconnect or carriers reset sessions |
| Best fit | Location-specific research, SEO monitoring, price comparison and large-scale public data collection | Checking how sites and ads appear to mobile users, and carrier-specific testing |
Protocol support and login methods also depend on the provider. Check that the plan supports your app’s HTTP, HTTPS or SOCKS5 setup before buying.
Choose mobile when you need a mobile carrier’s IP. Choose rotating residential when you need a pool of home-network IPs in suitable locations. Choose static residential/ISP when keeping one address matters most.
Test a small sample on your actual websites before buying more, and follow those sites’ terms.
