Where the addresses come from#
Consumer providers lease blocks of their address space to datacenters under contract; the WHOIS and geolocation records keep the ISP's name, so reputation systems see a residential provider. That supply exists in a limited number of countries, which is why ISP proxy catalogues are shorter than residential ones and why prices differ by country.
ISP versus residential versus datacenter#
| ISP proxy | Residential proxy | Datacenter proxy | |
|---|---|---|---|
| Registered to | Consumer ISP | Consumer ISP | Hosting company |
| Hosted on | Datacenter uplink | A real household device | Datacenter uplink |
| Address | Static, yours for the term | Rotating or sticky, shared pool | Static, yours for the term |
| Traffic | Usually unlimited | Per GB | Pooled or unlimited |
| Best for | Accounts, logins, checkout | Scraping, SERP, ads, monitoring | Bulk collection, monitoring, QA |
When to choose it#
Anything that must keep one trusted address for weeks: account management, marketplace and ad dashboards, checkout and limited releases, long authenticated scraping sessions, or a fixed egress that the other side can whitelist.
How it works at ProxShift#
ProxShift ISP proxies come from an inventory of 550K+ static residential addresses and are sold in 33 countries for 24 hours, 30, 60 or 90 days, with unlimited traffic, from $0.99 per IP per month on a 90-day term in the United States; other zones are priced at published multiples and orders of 10, 50, 100 and 500 IPs take 5, 10, 20 and 25 % off.
Questions people ask#
Is an ISP proxy detectable as a datacenter address?
Reputation systems that look at the registered owner see a consumer ISP; those that also look at hosting behaviour (no residential traffic patterns, static route) can classify some ranges as hosted. In practice ISP proxies pass most checks that block plain datacenter ranges.
Can I choose the city?
Country is always chosen at the order; city where the pool in that country allows it. For city precision in every country, residential proxies are the better tool.
