What is a Comcast proxy?
A Comcast proxy is a proxy server that routes your request through an IP registered to Comcast Cable Communications, which serves roughly 29M US broadband households. Target servers see Comcast as the owning organization, not your network.
You’ll also see these referred to as Xfinity proxies. It’s the same product – Xfinity is Comcast’s retail brand for consumer broadband, and both names point to the same network.
Because Comcast sells consumer broadband rather than hosting, a Comcast proxy gives you an IP that appears as an ordinary household connection rather than server infrastructure. Comcast’s main autonomous system, AS7922, announces roughly 68M IPv4 IPs across the US, and that’s the pool Comcast proxies draw from.
Comcast proxies are part of Decodo’s broader proxy network, spanning residential, ISP, mobile, and datacenter IPs across 195+ locations. They route traffic through a residential proxy registered to Comcast, with AS7922 targeting for precise network-level targeting.
What does a Comcast proxy do?
Comcast proxy swaps the IP in your outbound request with another IP that belongs to Comcast, so the destination server attributes your traffic to a US household connection rather than to yours.
That matters in 3 situations:
- You’re checking how a website treats traffic from a major consumer ISP.
- You’re collecting public web data and want requests attributed to household connections rather than a hosting provider.
- You’re testing your own product under the network conditions your largest US customer segment actually connects on.
Why use Decodo’s Comcast proxies?
Getting IPs on a specific consumer ISP is otherwise slow, expensive, or unreliable. Building your own pool on Comcast lines means managing residential accounts, hardware, and a proxy layer yourself. Decodo gives you carrier targeting as a self-serve parameter on existing pools, live in minutes.

What can you do with Comcast proxies?
Comcast proxies work well for large-scale data collection, multi-account management, and other workflows where the network behind each request affects the results.
Web scraping
Collect public web data through US household IPs instead of server ranges. Carrier targeting covers Comcast’s footprint in 1 parameter. Learn more
SEO
Audit search results and rankings at scale from consumer ISP IPs. Datacenter ranges are quickly rate-limited on search targets, while household IPs sustain longer collection runs. Learn more
Multi-accounting
Run and manage multiple US accounts on consistent household IPs. Sticky sessions hold the same Comcast IP for up to 24 hours, keeping each profile separate. Learn more
ISP comparison
Run the same requests on AS7922 and another carrier’s ASN, then diff the results. Swapping 1 parameter isolates network reputation as a variable, which a geo-targeted pool can’t do. Learn more
Artificial intelligence
Feed models with web data collected from real consumer connections. Pair Comcast proxies with Decodo’s Web Scraping API to automate large-scale pipelines without hitting CAPTCHAs. Learn more
Product QA
Test your own app the way Comcast subscribers experience it. Real latency, real routing, and real network identity from the largest US broadband provider surface ISP-specific issues early. Learn more
How does the Comcast network work?
Carrier targeting only pays off if you understand the network behind it. Here's Comcast's US footprint, how target websites read its IPs, and why those IPs change hands.
Where are Comcast IPs located?
Across 41 states and Washington, DC. Xfinity's footprint reaches roughly 126M people, with the densest coverage in DC, Maryland, and Massachusetts, and major metro concentration in Philadelphia, Chicago, Atlanta, Denver, Houston, and the Bay Area.
Why do websites treat Comcast IPs differently?
Because AS7922 is a consumer broadband network, not a hosting network. Reputation systems score traffic partly based on the ASN it arrives on, and the 2 categories have different baseline expectations.
How does Comcast assign IPs?
Dynamically, through DHCP leases that renew on a set interval. A subscriber's IP can change when the lease renews, or the modem reconnects.
Is using a Comcast proxy legal?
Collecting publicly available web data through proxies is lawful in most jurisdictions. What determines your exposure is how the IPs were sourced and what you do with them, not the proxy itself. Check your own obligations, since terms of service and local law vary.
Which proxy type do you need for Comcast IPs?
Residential and ISP proxies work for Comcast.
The other types don't carry Comcast IPs, though they solve adjacent problems. Datacenter proxies trade network identity for throughput and cost-per-request. Mobile proxies cover 3G/4G/5G carrier networks, which Comcast doesn't operate.
If you came looking for a "Comcast ISP proxy," the product you probably want is a static residential proxy. It holds 1 IP indefinitely with residential-grade reputation, though the carrier behind it is assigned rather than chosen.
Xfinity Mobile is worth ruling out explicitly. It runs as an MVNO on a partner carrier's network, so those IPs carry that carrier's ASN rather than Comcast's.

A2A vs. MCP: Comparing AI Agent Communication Methods
MCP (Model Context Protocol) connects one AI application to tools, data, and APIs. A2A (Agent2Agent) lets independent agents delegate work across trust boundaries. A2A vs. MCP is a question of layers, not competition. The usual mistake is adding a second agent where better tools would be enough. This guide measures both and shows which to build on.

How Residential Proxies Work: A Technical Guide to Types, Networks & IP Sourcing
A residential proxy network routes your traffic through real ISP-assigned home IPs. But how routing actually happens, which proxy types you end up using, and how IPs are sourced have a much bigger impact on success rates. This guide breaks down how residential proxy networks work, including ASN-level routing, the different types of IPs, and the protocols they support.

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 Comcast proxies before I commit to a plan?
Start a 3-day free trial that includes 100MB of traffic, with no credit card required.
The trial opens up every proxy type, so you can test AS7922 targeting on the residential pool before deciding on a plan size. If you’d rather test Decodo’s Web Scraping API, there’s a separate free starter plan with up to 2K requests.
How do I get my money back if Comcast proxies don’t fit my project?
Paid subscriptions come with a 14-day money-back option (terms apply), and you can cancel at any time from the dashboard.
The guarantee doesn’t apply if you started on the free trial, so pick 1 route or the other depending on which matters more to you. After you cancel, your subscription remains active until the end of the current billing period, rather than stopping immediately.
How do I target Comcast IPs in a specific city or ZIP code?
You can’t combine them. ASN targeting and geographic targeting are mutually exclusive, so asn-7922 and city-chicago can’t run in the same request.
Pick whichever variable your target actually reacts to. If the page changes by location, use city or ZIP targeting and accept a mixed set of carriers. If it changes by network, use asn-7922 and accept a US-wide spread of IPs. When you need both, run 2 passes and compare, which also tells you which variable is doing the work.
How do I confirm the IPs I receive are actually on the Comcast network?
Send a request through the proxy to https://ip.decodo.com/json and check the organization field in the response.
If carrier targeting is applied correctly, the response names Comcast Cable Communications and returns 7922. 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 get sourced and attributed, see this technical guide to residential proxy networks.
How do I set carrier targeting in my proxy endpoint?
Append asn-7922 to your username string, then connect to gate.decodo.com:7000 as usual. The full string reads user-YOUR_PROXY_USERNAME-asn-7922.
Your username carries the targeting instructions, so nothing in your client code changes beyond the credential string. Session parameters stack with the ASN parameter, so you can combine carrier targeting with sticky sessions. Location parameters don’t. The full parameter reference lives in the dashboard.
How do I keep the same Comcast IP across a multi-step workflow?
Use a sticky session, which holds 1 IP for the duration you specify.
Add a session value to your username, then set the session duration anywhere from 1 to 1440 minutes. Session parameters combine with carrier targeting without conflict. Build in re-authentication for long sessions, since the IP can rotate early if the residential device behind it drops offline.
