Chicago residential proxies by ISP: Comcast and AT&T

Which internet providers serve Chicago homes?

Out of 1,316,431 residential units in Chicago, 98.5% can get Comcast, 89.4% AT&T and 53.9% Astound, per the FCC National Broadband Map. The table lists all 7 non-satellite providers in the FCC's top ten for the city. T-Mobile Home Internet (87.1%) and Verizon 5G Home (63.8%) are mostly 5G fixed wireless home internet, whose IPs share the carrier's mobile network.

What broadband technology do Chicago homes use?

Fiber reaches 33.3% of Chicago's residential units, 41st of the 45 cities we track and below the 62.2% median. Cable is almost everywhere (99.2%), so a cable IP is the most common home connection type. Copper DSL is still reported at 67.2% of units, 8th highest of our cities, so some telco IPs here sit on older lines. Gigabit service (1,000/100 Mbps) is available to 54.5% of units. Access type matters for testing: fiber and cable homes usually get their own public IPv4 address, while fixed wireless users often share one.

How do I target a Chicago ISP in my proxy username?

Start from the city: USERNAME-country-us-state-il-city-chicago asks for any home IP in Chicago. Then add the ASN of the provider you need:

• USERNAME-country-us-state-il-city-chicago-asn-7922: Comcast in Chicago.
• USERNAME-country-us-state-il-city-chicago-asn-7018: AT&T in Chicago.
• USERNAME-country-us-state-il-city-chicago-asn-6079: Astound in Chicago.
• USERNAME-country-us-zip-60614-asn-7922: Comcast in ZIP 60614 (Lincoln Park).
• USERNAME-country-us-state-il-city-chicago-asn-7018-session-chicag1-ttl-20: one AT&T IP kept for up to 20 minutes.

Use gw.broadbandproxies.com, port 7777 for HTTP and HTTPS or 7778 for SOCKS5. If a request finds no IP online, drop the ZIP first, then the city, and keep the ASN.

Chicago: cable almost everywhere, fiber in a third of homes

Comcast reports service to 98.5% of Chicago's 1.3 million residential units, and Astound's RCN network (AS6079) to 53.9%, so most homes have two cable choices. Fiber reaches only 33.3% of units, 41st of our 45 cities, while copper DSL is still reported at 67.2%. AT&T, at 89.4%, is the main telco and the source of most fiber and DSL lines.

Which IL rules matter for checks from Chicago?

Illinois had no comprehensive consumer privacy law as of October 2026; the closest is the Illinois Biometric Information Privacy Act (BIPA, 2008), which covers biometric data only. Prices shown to Chicago shoppers may add sales tax at checkout: the combined state and local rate is 10.50% since 2026-08-01, so compare pre-tax prices when you check retail pages from a Chicago IP. Chicago is on Central Time: schedule checks of time-limited offers and local ads in that zone. Whatever the city, our acceptable use policy applies; blocked targets: Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587.
