What is a Cogent proxy?
A Cogent proxy is a proxy server that assigns you an IP address registered to Cogent Communications, a tier-1 internet backbone operating under AS174. Target servers see Cogent as the owning organization, not your network.
Cogent is a business and transit ISP, not consumer broadband, so its addresses read as business infrastructure. According to Cogent, there are about 24.2M IPv4 addresses across 50+ countries.
Cogent proxies are one option within Decodo's broader proxy network, which covers ISP, mobile, and datacenter IPs. Where you need household-grade addresses instead, a residential proxy draws from the same 125M+ pool.
What does a Cogent proxy do?
Cogent proxy replaces your original IP address with one that belongs to the Cogent network, so the destination server attributes your traffic to Cogent rather than to your own connection.
This comes in handy in various situations:
- You're collecting public data and want your requests distributed across a defined, stable set of addresses instead of a random pool.
- You’re testing your own infrastructure and need to reproduce traffic conditions from a known upstream network.
Why use Decodo's Cogent proxies?
Getting IPs on a specific autonomous system is slow, pricey, or unreliable. Leasing from Cogent directly means contracts and running your own proxy layer. Free lists claiming Cogent IPs are often unverified and usually blocked by most of the anti-bot software. With Decodo, ASN targeting is just a parameter on an existing pool, live in minutes.

What makes Cogent proxies different?
Unlock all the handy features and equip ethically-sourced proxies for any use case.
Targeting by parameter
Add the ASN to your username string on requests you already send. Same plan, same pricing, no upgrade required.
99.99% uptime
Monitored infrastructure with automatic failover, so a single node going down does not stop your collection.
Sub-0.2 second ISP response
Static residential IPs answer in under 0.2 seconds, which is what makes them viable for latency-sensitive collection.
Unlimited-duration sessions
Hold the same ISP proxy IP for as long as a task needs, with no forced rotation interval cutting a workflow short.
Unlimited concurrent connections
Run as many parallel requests as your own infrastructure can sustain. No connection cap on the proxy side.
HTTP(S) and SOCKS5 on one endpoint
Use the protocol your tooling expects. Both are available on the same credentials with no separate plan.
How do you get started with Cogent proxies?
Setting up Cogent proxies takes just a few minutes, free trial included.
#1 Sign up and access the dashboard
Create your Decodo account and log into the dashboard. Everything you need to manage proxies, monitor usage, and adjust targeting lives here, so take a moment to get familiar with the layout.
#2 Choose your proxy type
Pick ISP or datacenter proxies for the closest match to Cogent's commercial address space, or residential if you need household-grade IPs. Start with a 3-day free trial and 100MB to test any type before subscribing.
#3 Set up your proxies
Follow the quick start guide to configure the proxy on your device or tool of choice. Pick HTTP(S) or SOCKS5 depending on what your browser, scraper, or automation setup supports. Both run on the same credentials.
#4 Target the Cogent network
Add the ASN parameter to your username string to route through AS174. Depending on your proxy type, you can pair it with other targeting options.
#5 Verify and start collecting
Send one request to ip.decodo.com/json. If the response names Cogent Communications, your targeting is live and you are ready to collect. Run this check at the start of each job rather than assuming.
How do I use sticky and rotating sessions with Cogent proxies?
With Decodo, you can choose between rotating and sticky session types, depending on your use case. Sticky sessions keep the same IP for a set period, and ISP proxies support unlimited-duration sessions, so an address stays with you for as long as a task runs. That makes them the go-to for account management, multi-step workflows, or anything where switching IPs mid-task would cause problems.
Rotating sessions switch to a new IP with each request, which is what you want when you are collecting data at scale and need maximum IP diversity to keep success rates high.
Simple rule of thumb – sticky for anything that needs a consistent identity, rotating for anything that benefits from volume.
How do I connect Cogent proxies to my scraper?
Point your HTTP client at isp.decodo.com:10001 and pass your credentials with the ASN parameter in the username. Nothing else in your code changes, and no SDK is required.
Anything that speaks HTTP(S) or SOCKS5 works, which covers Python with requests, Node.js with axios, cURL, Scrapy, Playwright, Puppeteer, and Selenium. For a complete pipeline, you can pair proxies with Decodo's Web Scraping API, which handles JavaScript rendering and returns HTML, JSON, CSV, or Markdown.

Agentic Commerce: Why AI Shopping Agents Get Blocked
Agentic commerce means an AI agent does the shopping: it searches catalogs, compares prices, and sometimes checks out. Retailers are meant to expose a protocol for that. When none is published, the agent reads the product page like a person. We ran 10 US retailer pages through 4 clients, and the best one we built read 5 of them. Adding a real browser didn't help. Correcting its client hints did.

Datacenter & ISP Proxies Now Support City, State & ASN Targeting
City, state, and ASN targeting now works across datacenter and ISP proxies. Country-level targeting set the ceiling before, which pushed some geo-sensitive work to residential. That limit is gone. You can now target a specific metro, a US state, or a named network, all from your current setup.

Residential vs Datacenter Proxies: Which Should You Choose?
At first glance, residential and datacenter proxies may seem the same. Both types act as intermediaries that hide your IP address, allowing you to access restricted websites and geo-blocked content. However, there are some important differences between residential and datacenter proxies that you should know before making a decision. We’re happy to walk you through the differences so you can choose what's right for you.

Frequently asked questions
How do I try Cogent proxies before I commit to a plan?
Start a 3-day free trial that includes 100MB of traffic.
The trial gives you access to every proxy type, so you can test ASN targeting on ISP, datacenter, residential, and mobile IPs before deciding which fits your workflow. If you would rather test the Web Scraping API, there’s a separate free plan with up to 2K requests, no credit card required.
How do I get my money back if Cogent proxies do not fit my project?
Paid subscriptions come with a 14-day money-back (terms apply), and you can cancel from the dashboard at any time.
How do I confirm the IPs I receive are actually on the Cogent network?
Send a request through the proxy to https://ip.decodo.com/json and check the organization field in the response.
If ASN targeting is applied correctly, the response names Cogent Communications and returns AS174. Run this check once at the start of a job rather than assuming, since pool composition shifts over time. For background on how proxy IPs are sourced and attributed, see how residential proxies work.
How do I choose between ISP, datacenter, and residential proxies for Cogent traffic?
Start with ISP proxies, since Cogent is a commercial fixed-line network and ISP proxies are the closest match to its address space.
Move to datacenter proxies when throughput and cost per request matter more than the trust profile of the address. Choose residential proxies when the target treats household connections differently, and you’re willing to widen beyond a single autonomous system to get that. Mobile proxies aren’t a match here, because Cogent doesn’t operate a consumer mobile network.
How do I set ASN targeting in my proxy endpoint?
Append the ASN parameter to your username string in the proxy credentials, then connect to the standard gateway as usual.
Your username carries the targeting instructions, so nothing in your client code changes beyond the credential string. Geographic parameters combine with the ASN parameter, letting you narrow to Cogent addresses in a specific country or city. The full parameter reference is in the dashboard, and this guide to datacenter and ISP proxy targeting walks through worked examples.
How do I keep the same Cogent IP across a multi-step workflow?
Use a sticky session, which holds one IP for the duration you specify.
ISP proxies support unlimited-duration sessions, so the address stays with you for as long as the task runs rather than rotating at a fixed interval. Residential proxies offer sticky sessions of 1, 10, or 30 minutes, or custom. Use sticky sessions when the workflow needs a consistent identity, and rotating sessions when you want maximum address diversity across many independent requests.
