Quick answer
How can I see the broadband offers a household on another network gets?
Broadband offer checks compare what ISP and comparison sites show to homes on each network: address results, promo banners, prices and customer notices. Broadband Proxies runs these checks from US home IPs chosen by ASN, city or ZIP, from $0.50/GB. Work by hand or at low volume, within each site's robots.txt and terms. There is no KYC, and you pay in crypto.
Offer checks at a glance
| Who runs them | Comparison sites, ISP marketing and pricing teams, telecom analysts |
|---|---|
| What can change by network | Promo banners, plan order, prices after an address check, notices for people already on that network |
| Targeting | ASN, state, city and ZIP in one username, e.g. USERNAME-country-us-zip-19103-asn-701 (Verizon Fios, ZIP 19103) |
| Session | Sticky for address checkers: up to 30 minutes (the IP can change earlier, for example if the home device goes offline) |
| Pace | Manual browser checks or a few requests per minute; robots.txt and site terms first |
| Price | $2.63 for 1 GB, $5.94 for 10 GB; traffic never expires |
| Payment | Crypto only, no KYC |
Why does an ISP show different offers to different households?
Providers price by market, and competition differs from one city to the next. In Charlotte, the FCC map lists Spectrum at 95.4% of residential units, AT&T at 91.1% and Google Fiber at 18.7%. In Phoenix, Cox reaches 89% and CenturyLink 85.5%, while fiber covers only 27.2%. Data as of December 31, 2025.
A cable operator facing a fiber rival may show a sharper promo than it does elsewhere. Many sites also read the visitor's IP. When the IP sits on their own network, the page may show an upgrade path or an existing-customer notice instead of new-customer prices.
Markets in transition are worth watching too. After Charter closed the Cox deal on August 19, 2026, Spectrum branding and pricing started in former Cox markets from mid-September, per trade press. Phoenix and Las Vegas are two of those markets.
Is the IP the only signal an offer page uses?
No. The street address you type is often the strongest signal, followed by cookies and any signed-in account. Use a clean browser profile for each network, and never sign in to a customer account.
For address checkers, use a public address such as a library or a city hall. Never type a private person's home address. Do not submit orders, and do not create accounts to reach a price. If a site offers a partner feed or an affiliate data file, use that instead of page checks.
Which network and session fit each check?
| Check | Example network and place | Username | Session |
|---|---|---|---|
| New-customer price after an address check | Spectrum in Charlotte, AS11426 | USERNAME-country-us-state-nc-city-charlotte-asn-11426-session-offer1-ttl-15 | Sticky |
| Existing-customer notice on the ISP's own site | Comcast in Atlanta, AS7922, against AT&T, AS7018 | USERNAME-country-us-state-ga-city-atlanta-asn-7922 | Sticky, one per ASN |
| Promo banner in a former Cox market | Cox network in Phoenix, AS22773 | USERNAME-country-us-state-az-city-phoenix-asn-22773 | Rotating |
| Comparison-site results for one ZIP | Verizon Fios, AS701, ZIP 19103 | USERNAME-country-us-zip-19103-asn-701 | Rotating |
| Fiber against cable in one city | AT&T, AS7018, and Spectrum, AS11427, in Dallas | USERNAME-country-us-state-tx-city-dallas-asn-7018 | Rotating |
Spectrum still routes many regions on their own AS numbers, such as AS11427 in Texas and AS11426 in the Carolinas. Each ISP page lists them.
How do I run a low-volume offer check?
Read the rules of the site
Check robots.txt and the terms of use. Skip any page or site that forbids automated access.
Choose networks from FCC data
Each city page lists the providers with their share of residential units and their ASN.
Open one sticky session per network
Run the script below. It logs the exit IP and the origin ASN of each session before you start.
Do the flow by hand
Use one clean browser profile per session. Note the price, the promo text and any notice, and take a screenshot.
Spread the checks over time
Repeat on other days, not in bursts. A weekly snapshot per network and city is usually enough to see a change.
#!/usr/bin/env bash
# Open one sticky session per network in Charlotte and log where each one exits.
# Use each username afterwards for a manual offer check in a clean browser profile.
GATEWAY="gw.broadbandproxies.com:7777"
PASSWORD="PASSWORD"
BASE="USERNAME-country-us-state-nc-city-charlotte"
for ASN in 11426 7018 16591; do # Spectrum, AT&T, Google Fiber
USER="${BASE}-asn-${ASN}-session-offer${ASN}-ttl-15"
IP=$(curl -s --max-time 30 -x "http://${USER}:${PASSWORD}@${GATEWAY}" \
"https://api.ipify.org?format=json" | sed -E 's/.*"ip":"([^"]+)".*/\1/')
ORIGIN=$(curl -s --max-time 30 \
"https://stat.ripe.net/data/prefix-overview/data.json?resource=${IP}&sourceapp=offer-check" \
| grep -o '"asn": *[0-9]*' | head -n 1 | grep -o '[0-9]*$')
echo "$(date -u +%Y-%m-%dT%H:%M:%SZ) user=${USER} ip=${IP} origin=AS${ORIGIN:-unknown}"
sleep 20
doneWhat rules apply to broadband offer checks?
Offer checks read public pages slowly, as a shopper would. Our Acceptable Use Policy forbids entering accounts that are not yours and creating accounts in bulk. It also forbids floods of traffic against systems whose owner has not agreed, and asks you to respect each site's terms and robots.txt. Do not place test orders you will not keep.
Prefer manual checks in a browser. If you script part of the work, keep to a few requests per minute per site. Stop when the site returns errors or a challenge page. Banking, government and payment-portal sites are blocked on every plan.
How much does a program of offer checks cost?
Each check is a short browser session, so traffic depends on the weight of the pages you open. Start with 1 GB ($2.63) on two networks in one city. Move to 10 GB ($5.94) or 50 GB ($25.99) for weekly snapshots across many cities. Traffic never expires.

Broadband offer checks: questions
Can I see the price a Spectrum customer sees as an existing customer?
You can see what a visitor on Spectrum's network gets before signing in, such as an upgrade banner or a notice. Prices tied to a real account need that account, and signing in to accounts you do not own is forbidden. Use asn-11426 in Charlotte or asn-11427 in Texas for Spectrum regions.
Which address should I type into an availability checker?
Use a public address, such as a library, a school office or a city hall, inside the area you are testing. Never type a private person's home address. Record the address with the result, so a colleague can repeat the check on the same network and get a comparable answer.
Can I scrape a comparison site with these proxies?
Only where its robots.txt and terms allow it, and at low volume. Many comparison sites sell data feeds or run partner programs; those are faster and cleaner than page checks. For spot checks, a person in a browser with a sticky session gives the most faithful view of the offer.
Why do I get the same offer on every network?
Many providers price by address, not by IP. If the street address decides the offer, the network will only change banners or notices. Compare two networks with the same public address and a clean profile. If nothing changes, the IP is not a pricing signal on that site.
Can I target one ZIP code on one ISP?
Yes, ZIP and ASN can share a username, for example USERNAME-country-us-zip-19103-asn-701 for Verizon Fios in ZIP 19103. City availability varies; the checkout shows what is online. If no IP is online, drop the ZIP and keep the city, or try again later in the day.
Do I need company documents to buy?
No. Broadband Proxies works without KYC, so no ID card, selfie or company papers are uploaded at any step. You pay in crypto; the minimum top-up is $25. Account-number login; email is optional. Sub-users let a team split traffic between clients or markets.
