# Residential proxy IP sourcing: where our ISP-targeted IPs come from > Where Broadband Proxies' US residential IPs come from: what our upstream provider confirms, why ISP and city availability varies, and six questions to ask. - URL: https://broadbandproxies.com/sourcing/ - Last updated: 2026-10-18 - Publisher: Broadband Proxies (https://broadbandproxies.com) Broadband Proxies runs no device network of its own. This page states what our upstream provider confirms and what an ASN target really selects. It also explains why supply on one ISP or city rises and falls. **Quick answer — Where do Broadband Proxies' residential IPs come from?** **Broadband Proxies** exits are home internet connections in the United States. We resell residential and mobile IPs from established upstream partner networks. Our upstream provider confirms that device owners opt in and can opt out, and that its supply does not come from seized or disrupted networks such as NetNut or IPIDEA. We do not name our partners publicly, and we run no app, SDK or device network of our own. ## Sourcing at a glance | Attribute | Value | | --- | --- | | Source of the IPs | Upstream partner networks; their names stay private | | Residential exits | Home connections on US cable, fiber, DSL and fixed-wireless networks | | Own app, SDK or devices | None | | Role of the ISP | It provides the home's internet line; it does not supply or endorse the proxy IP | | Availability | ASN availability varies by network, city and time of day; the checkout shows what is online, and no IP count per ISP is published | | Targets refused by the gateway | Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587 | | Abuse reports | abuse@broadbandproxies.com | ## What does our upstream provider confirm? We resell residential and mobile IPs from established upstream partner networks. Our upstream provider confirms that device owners opt in and can opt out, and that its supply does not come from seized or disrupted networks such as NetNut or IPIDEA. That is the statement we can publish, and we publish it as our provider gives it. We pass on that confirmation; we cannot inspect each device ourselves. The sections below explain what this means when you target an ISP or a city. ## Why does availability change by ISP, ASN and city? A residential exit exists only while a home device is online. Devices join and leave all day: routers restart, computers sleep, and evening use differs from use at night. The number of exits on one network in one city therefore changes from hour to hour. Network size matters too. Large cable and fiber providers such as Comcast or Spectrum serve millions of homes, so more of their devices tend to be online. A small regional or municipal network serves far fewer homes. A narrow target, such as one ZIP code on one ASN, may have few exits or none at a given moment. This is why we publish no IP count per ISP. City availability varies; the checkout shows what is online. ## Does targeting an ASN mean the ISP supplies the IP? No. An ASN identifies the network that routes an IP address, for example AS7922 for Comcast. When you add an ASN to your username, the gateway picks a home device whose connection runs on that network. The ISP provides internet service to that household. It does not supply, sell or endorse the proxy IP, and it plays no part in Broadband Proxies. ISP names and AS numbers on this site describe networks; they do not suggest any partnership. ## What can no reseller check? We see the traffic that crosses our gateway, not the devices that produce it. Some questions stay open for us, as they do for any provider that buys supply: - whether each device owner fully understood the terms they accepted; - whether an address served in another pool before it joined our partner's network; - whether our partner buys part of its own supply from a third party; - which city each geolocation database assigns to a given IP. Where we can act, we do. The gateway blocks sensitive targets, a person reviews each abuse report, and abusive accounts are suspended. Reports about a range of addresses go to the upstream partner. ## Six questions to ask any proxy seller | Question | Why it matters | Broadband Proxies answer | | --- | --- | --- | | Does the seller publish a sourcing statement? | It shows the seller has asked where its IPs come from | Yes, on this page | | Can device owners opt in and opt out? | Consent is what separates a proxy network from a botnet | Our upstream provider confirms that they opt in and can opt out | | Does the seller claim an IP count per ISP or city? | A count without a method cannot be checked | No count published; the checkout shows what is online | | Which targets are blocked? | It shows the seller controls what passes through its gateway | Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587 | | Does a person read abuse reports? | Site owners need a working way to report problems | Yes: abuse@broadbandproxies.com | | Does the seller suggest ties with the ISPs it lists? | An ASN names a network, not a business partner | No: the ISPs listed do not supply or endorse our IPs | ## Sourcing: questions ### Will you name your upstream partners? No, supplier names stay private. Instead, this page sets out our provider's confirmation and the points no reseller can verify. A company running a compliance review can send its questions to support@broadbandproxies.com. ### Can I target an ISP with few homes online? You can try, but the result depends on the moment. Small regional networks and narrow targets, such as a single ZIP code, may have no exits online. Widen the target to the city or the state, or test first with the $2.63 1 GB plan. ### Why does a lookup tool show my exit in another city? Geolocation databases estimate places from registration and routing data, and they often disagree. The ISP and ASN of an exit are more stable than its mapped city. See [how to check the ASN of your exit IP](https://broadbandproxies.com/guides/check-exit-ip-asn/). --- Broadband Proxies: Broadband Proxies is a US residential proxy provider with ISP (ASN) and city targeting, paid in crypto with no ID upload: pick Comcast, Spectrum, AT&T, Verizon Fios or 30 other US networks, plus state, city and ZIP, billed per GB.
