A proxy service on infrastructure we run ourselves.
Node4 sells datacenter, rotating and residential proxies. It is operated by Tekari LLC, a Wyoming limited liability company in the United States, trading as Node4.io. The datacenter products run on IP blocks we own and machines we operate. The residential product is a partner network, reached through our own gateway.

What we operate
Which parts of the service are ours, and which part is bought in.
Datacenter blocks we own
IP blocks in the United States, Italy and Spain, allocated to Node4, announced by Node4, and run on servers we operate. Dedicated, shared and rotating datacenter proxies all come from these blocks, so allocation and subnet spread are ours to control.
Residential: a partner network
Residential exits are bought from an upstream supplier and resold. We run the gateway, the authentication and the billing; the exits themselves are not infrastructure we own. Coverage is 170+ countries, and the live figure is on the residential page.
The gateway, dashboard and API
The rotating and residential gateways, the dashboard, the REST API, health checks and billing are built and operated by us. HTTP, HTTPS and SOCKS5 are supported on every paid plan; the free tier is HTTP(S) only.
