Quick verdict: ISP proxies (also called static residential) are residential IPs hosted in datacenters — you get the trust score of a Comcast home IP with the speed and stability of a server rack. Datacenter proxies are pure server IPs from AWS, Hetzner, OVH, etc. — cheapest and fastest, but trivially detected by any anti-bot system that checks ASN. Use ISP when you need stealth on stubborn targets (Instagram, sneaker sites, ad networks); use datacenter when the target doesn't care and you want unlimited bandwidth for pennies.
| Datacenter | ISP / Static Residential | |
|---|---|---|
| Hosted in | Datacenter | Datacenter |
| IP registered to | Hosting provider (AWS, OVH, Hetzner) | Consumer ISP (Comcast, AT&T, BT, Deutsche Telekom) |
| ASN type | Hosting / cloud | Residential ISP |
| IP rotation | Static (dedicated) or rotating (shared pool) | Static by definition |
| Speed | 1–10 Gbps uplink | 1–10 Gbps uplink |
| Detection risk | High — trivially ASN-flagged | Low — looks like home internet |
| Price (2026) | From $1.50/proxy/month | From $3.90/day per IP |
The trick is that ISP proxies live in the same buildings as datacenter proxies. The difference isn't physical — it's the IP registration record. An ISP proxy provider leases blocks of IPs from a consumer ISP and routes them to servers in a datacenter; to any anti-bot system doing a WHOIS or ASN lookup, those IPs look like residential broadband.
Both run at full datacenter uplink — typically 1–10 Gbps and sub-50ms latency to major cloud regions. There is no meaningful speed difference. If you see slow ISP proxies, the bottleneck is the provider's rate-limiting or shared backplane, not the technology. Both crush rotating residential pools, which route through real consumer DSL / fiber connections at 50–500 Mbps.
This is where ISP earns its premium. Anti-bot systems classify by ASN reputation first; the lookup costs them nothing and rules out 90% of scraping traffic. AWS, Linode, Hetzner, OVH, Vultr ASNs are pre-flagged. ISP proxy IPs come from ASNs like Comcast (AS7922), AT&T (AS7018), BT (AS2856) — broadband ASNs the same anti-bot list treats as low-risk.
| Site / system | Datacenter blocks | ISP blocks |
|---|---|---|
| Generic websites | Rare | Rare |
| Cloudflare (default) | Sometimes | Rare |
| Cloudflare Bot Fight Mode | Almost always | Sometimes |
| Instagram / TikTok / Facebook | Almost always | Rare (when warmed) |
| Sneaker sites (Nike SNKRS, Footlocker) | Always | Sometimes |
| Ticketing (Ticketmaster, See Tickets) | Always | Sometimes |
| Ad networks (Google Ads, Meta Ads) | Always | Rare |
By definition, ISP / static residential proxies are static — each IP is dedicated and stays with you for the contract period. This is the right model for account management and any flow that needs cookie persistence.
Datacenter proxies come in both flavors: static datacenter (dedicated IP, same as ISP's static model) and rotating datacenter (pool of shared IPs that rotate per request). Rotating datacenter is fast and cheap for scraping non-protected sites at volume; static datacenter is a one-IP-per-customer arrangement when you need a stable identity but don't need residential trust.
People often confuse "static residential" (ISP) with "residential". They're different products:
Rotating residential wins on scale and stealth-per-dollar for volume scraping. ISP wins on speed and session persistence for account management. Many serious operators use both: rotating for crawl, ISP for the few accounts that need consistent identity.
If you're using an ISP proxy for an Instagram or TikTok account, treat the IP like a real home IP: keep the same IP indefinitely, do not pair it with multiple accounts, run human-like activity for 7–14 days before pushing volume. The whole point of ISP is identity continuity; rotating ISPs defeats it.
| Question | Pick |
|---|---|
| Do I need the cheapest unlimited bandwidth? | Datacenter |
| Does the target block AWS/Hetzner ASNs? | ISP or Residential |
| Am I running social/ad/finance accounts? | ISP |
| Do I need an IP that won't change for weeks? | ISP or Static Datacenter |
| Do I need 100M+ unique IPs? | Rotating Residential |
| Am I scraping a public, unprotected site? | Datacenter |
