What is ISP Proxy?
A static proxy hosted in a data center but registered under a residential ISP, combining datacenter speed with residential trust and a zero fraud score. Also called a static residential proxy.
ISP proxies are a deliberate hybrid. The hardware sits in a data centre, so the connection is fast and always on, but the IP address itself is leased from a consumer internet provider and registered to them in the public routing records. A site looking up the address sees a residential ISP, not a hosting company.
Unlike rotating residential IPs, an ISP proxy is yours for the whole rental period. That fixed identity is what makes it the standard choice for account work: a social or marketplace account that logs in from the same trusted address every day looks far more normal than one that appears from a new city on each session.
Because you rent a specific address rather than drawing from a pool, ISP proxies are priced per IP per month rather than per gigabyte, and bandwidth is usually unmetered. The limit is coverage — ISP IPs only exist where a provider has struck a deal with a carrier, so the country list is much shorter than for residential.

Residential Proxy
A proxy that routes traffic through an IP address assigned by an ISP to a real home device, making requests appear to come from a genuine consumer.
Mobile Proxy
A proxy that routes traffic through a real 4G or 5G connection on a mobile carrier network, so the exit IP belongs to a phone operator rather than a hosting provider or a home ISP. Also called a 4G, 5G or cellular proxy.
Sticky IP
An IP address that remains assigned to your session for its duration, as opposed to rotating on each request.
Fraud Score
A risk rating (0–100) that anti-fraud systems assign to an IP. Lower is better; seamless ISP proxies carry a zero fraud score, so they are rarely flagged.
