Quick answer
How do I get a proxy IP from one internet provider in a US city?
Add asn- and the provider's AS number after the city: USERNAME-country-us-state-pa-city-pittsburgh-asn-7922 asks MetroProxies for a Pittsburgh IP on Comcast's network. ASN targeting costs nothing extra on plans from $0.50/GB (October 2026). Combining filters narrows the pool, so availability varies. No KYC; crypto only.

Why would I target an ISP inside a city?
Some websites and services behave differently by network, not only by place.
- ISP-specific pages and offers: streaming bundles, sports packages and provider portals check whether you come from their own network.
- Support and QA: reproduce what a customer on Cox in Phoenix or on Spectrum in Charlotte sees, including network-level redirects.
- Consistent samples: when you compare a city day to day, holding the ISP constant removes one source of variation.
Target the ISP that actually serves the city: requesting Cox in Chicago will fail, because Cox does not offer home internet there. Each city page lists the providers with their FCC coverage shares and the AS number of the largest one.
How do I find the ASN of an IP I received?
Ask a routing database. RIPEstat's public API returns the AS number announcing any IP; Hurricane Electric's BGP toolkit shows the holder of an AS number. The Python example on the verification guide prints the city and the ASN of each exit in one call.
Two cautions. Large providers announce several ASNs: Charter uses AS20115 nationwide and regional numbers such as AS11427 in Texas. And mergers change owners before they change routing, so check the holder in RIPEstat rather than assuming from a brand name.
What else do people ask about ASN targeting?
Does ASN targeting cost extra?
No. It is part of every MetroProxies plan, from $1.50 for 1 GB (October 2026). On 18 October 2026, SOAX listed ASN targeting only on its Scale ($1,500/month + VAT) and Enterprise plans, and IPRoyal's documentation said ISP targeting needs a verified ID and $1,000 spent.
Is a residential IP on AT&T the same as an AT&T mobile IP?
No. AS7018 is AT&T's wireline home network. AT&T's mobile network uses other ASNs, and residential targeting does not select mobile carriers. The pricing page lists dedicated US 4G/5G ports, which are a separate product.
How many IPs do you have on each ASN?
We do not publish counts per ASN or per city. The FCC shares on our city pages describe how many homes each provider can serve, which is the market, not our pool. City availability varies; the checkout shows what is online.
Can I combine ZIP and ASN?
Yes: USERNAME-country-us-state-tx-city-austin-zip-78701-asn-20115. Each extra filter shrinks the pool, so start wide and narrow step by step.
