ISP Proxies

ISP (Internet Service Provider) proxies are hosted on datacenter infrastructure but use IP addresses assigned by real residential ISPs. Because the ASN belongs to a residential ISP, target sites see them as residential IPs — while the underlying datacenter hosting gives you the speed and stability you’d expect from a datacenter proxy.

IP Rotation Behavior

ISP proxies provide a static exit IP that persists across sessions — every tab, request, reconnection, and future browser session attached to this proxy exits through the same IP. The IP only changes in rare ISP-initiated replacement events (a few times per year on a small number of subnets).

This makes ISP proxies suitable for use cases that require a stable IP, such as IP allowlists or managed auth health checks. For comparison with other proxy types, see IP rotation behavior across proxy types.

Configuration

Create an ISP proxy:

Typescript/Javascript

import Kernel from '@onkernel/sdk';

const kernel = new Kernel();

const proxy = await kernel.proxies.create({
  type: 'isp',
  name: 'my-isp-proxy',
});

const browser = await kernel.browsers.create({
  proxy_id: proxy.id,
});

Configuration Parameters

• bypass_hosts (optional) - Array of hostnames that bypass the proxy and connect directly (max 100 entries)

Bypass hosts

Configure specific hostnames to bypass the proxy:

Typescript/Javascript

import Kernel from '@onkernel/sdk';

const kernel = new Kernel();

const proxy = await kernel.proxies.create({
  type: 'isp',
  name: 'isp-with-bypass',
  bypass_hosts: [
    'localhost',
    'internal.service.local',
    '*.amazonaws.com',
  ],
});

See the overview for full bypass host rules and examples.
