ISP Proxies

ISP (Internet Service Provider) proxies combine the speed of datacenter proxies with better legitimacy, as they use IP addresses assigned by real ISPs.

IP Rotation Behavior

ISP proxies provide a stable exit IP within a single browser session — every tab, request, and reconnection inside that session exits through the same IP, and it does not rotate mid-session (unlike residential).

For cross-session IP stability (e.g. IP allowlists or managed auth health checks), 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,
});

from kernel import Kernel

kernel = Kernel()

proxy = kernel.proxies.create(
    type="isp",
    name="my-isp-proxy",
)

browser = 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',
  ],
});

from kernel import Kernel

kernel = Kernel()

proxy = kernel.proxies.create(
    type="isp",
    name="isp-with-bypass",
    bypass_hosts=[
        "localhost",
        "internal.service.local",
        "*.amazonaws.com",
    ]
)
