The client's whole 45 GB a month fits inside one IP's 100 GB default allowance, so one IP is the unit of purchase.","notes":"Candidates for why the page yields no readable price, tested rather than assumed. (1) The form is rendered client-side: confirmed, the served HTML carries 'Price for 1 IP : $0' and the select elements hold ObjectId values, so the number is computed after hydration. (2) The $0.98 is a marketing floor reachable only at volume: consistent with the same page's 'Get a better per-IP rate with larger volumes or longer terms' and with its structured-data 'Minimum Price' of $3/IP, so the entry price at 1 IP is probably $3 and the $0.98 is a large-quantity rate — plausible, not established. (3) A WAF or geo-block was suppressing the price: refuted, the page returned 200 with the full article, the FAQ and the JSON-LD. Reading the ladder from https://proxy-seller.com/price/ was tried and ruled out: that page's ISP tab is drawn client-side and the table in the served HTML is the Residential per-GB ladder. What would settle the price: an account plus an API key, then orderCalcIsp across the 1w to 12mo periods at quantity 1, or simply the checkout for 1 IP for 1 week; the SDK makes this a scripted read rather than a browser session. The vendor names carriers (AT&T, Windstream, Frontier) and the survey names the AS numbers; I verified the numbers against RIPE as-overview and they agree with the carrier names, but the mapping from those ASNs to the addresses actually delivered is the vendor's claim and is untested here — the RIPE lookups are one per ASN on one date, and nothing else in this record rests on a single sample. The Fair the provider contradicts the marketing card and both are quoted rather than reconciled: 'Traffic is uncapped at any volume' against '100 GB of traffic by default' per IP, with no period stated and no way to buy traffic without buying an IP, which is why egress.metered is true while binding stays none at 45 GB a month. 'paid-only' was considered and rejected: the corpus's target includes cheapest-paid capacity, the minimum purchase is a single IP for a week, and the caveat belongs to the unverified price and the untested registration class rather than to the absence of a free tier. The schema's interface enum carries no proxy token, so interface holds 'rest' for the documented JSON API and the proxy protocols are in interface_detail, the shape dossier/storage/proxyrack-unlimited-residential.json already uses for a SOCKS5 product; the topic's own token list (socks5, http-proxy, api, web-ui) is not in schema.json and would fail the gate.","extras":{"rung":5,"rung_note":"The product is an address in an ISP-registered network, which is the rung-5 defence exactly; the vendor's 200+ Class B and 600+ Class C subnet claim would also reach rung 3, but it is unverified and no sample address is published, so only rung 5 is claimed.","price_signals":{"title_and_price_index":"$0.98/IP (page title, meta description, /price/ JSON-LD Offer with referenceQuantity 1 IP)","structured_data_minimum":"$3/IP (ISP page JSON-LD specification, name 'Minimum Price')","served_order_form":"$0 for 1 IP and $0 total, before hydration","ladder_readable_anonymously":false},"upstream_asns":[{"asn":"AS7018","holder":"ATT-INTERNET4 - AT&T Enterprises, LLC","announced":true,"checked":"2026-10-24"},{"asn":"AS7029","holder":"WINDSTREAM - Windstream Communications LLC","announced":true,"checked":"2026-10-24"},{"asn":"AS5650","holder":"FRONTIER-FRTR - Frontier Communications of America, Inc.","announced":true,"checked":"2026-10-24"}],"subnet_claim":"200+ Class B and 600+ Class C subnets, vendor's sentence, unverified","sample_address_published":false,"protocols":"HTTP/HTTPS/SOCKS5, credentials or IP allowlisting","address_behaviour":"static and non-rotating for the rental term","quantity_steps":"1, 25, 50, 100, 250, 500","period_steps":"1w, 2w, 1mo, 2mo, 3mo, 6mo, 9mo, 12mo","fair_usage":"100 concurrent threads and 100 GB of traffic per IP by default; 429 on the offending IP only","geo_targeting":"country at checkout; city or region by arrangement","per_gb_mode":"announced as 'Soon' in the calculator, not on sale","api_methods":"orderCalcIsp, referenceList(type='isp'), proxyList(type='isp'), balance","client_scale_fit":"45 GB/month and about 599,000 requests/month fit one IP's 100 GB and 100-thread allowance"}},"claims":[{"path":"$.free_tier.stated","kind":"free-quota","num":null,"unit":null,"per":null,"currency":null,"usd":null,"fx_date":null,"parse":"unparsed"},{"path":"$.limits[0].value","kind":"limit:per-ip-shaping","num":null,"unit":null,"per":null,"currency":null,"usd":null,"fx_date":null,"parse":"unparsed"},{"path":"$.limits[1].value","kind":"limit:volume-quota","num":100,"unit":"GB","per":null,"currency":null,"usd":null,"fx_date":null,"parse":"ok"},{"path":"$.limits[2].value","kind":"limit:per-ip-shaping","num":null,"unit":null,"per":null,"currency":null,"usd":null,"fx_date":null,"parse":"unparsed"},{"path":"$.price_per_tb_month","kind":"price-per-tb","num":0,"unit":"TB","per":"month","currency":"USD","usd":0,"fx_date":null,"parse":"ok"}],"unknown":[["$.per_object_cap.stated","not-applicable"]],"history":[],"drift":[]}
