Clean IP Use Case

# Low IPQS Score Proxies on Clean ISP IPs

Payment pages, ad platforms and sign-up forms read the IPQS score of your IP before they read anything else. CatProxies sells two kinds of private static ISP IPs for that check: Custom ISP Clean Score IPs, checked to a 0 score right before delivery, and the Premium ISP IPQS plan, with a low score or a free replacement.

- Custom ISP Clean Score: 0 on IPQS at delivery

- Premium ISP IPQS plan: low score or replaced free

- Private static IPs, one customer per IP

- Unlimited bandwidth, HTTP and SOCKS5

The Score

## What Is an IPQS Score?

IPQS, short for IPQualityScore, is a public IP reputation service. It rates every IP address from 0 to 100. The higher the number, the riskier the site considers the visitor, and 0 is as clean as an IP can be.

0

Clean

Nothing on record against the IP. The best result an address can have.

1 to 74

Ordinary

Most home connections sit here. Sites usually let the visit through.

75 to 84

Suspicious

IPQS marks this range as suspicious. Expect extra verification steps.

85 to 100

High risk

IPQS marks this range as high risk. Many sites refuse the request outright.

The score is built from the network the IP belongs to, proxy and VPN detection, abuse reports and the recent behaviour seen from the address. Other reputation services, such as Scamalytics and ipinfo, publish their own ratings, and a site may read any of them. An IP that is clean on IPQS is usually clean on the others as well.

Who Reads It

## Which Sites Check the IPQS Score?

Any page where money or identity changes hands. The score is read in the background, and the visitor only sees the result: a smooth checkout, an extra verification step or a refusal.

### Payment pages

Card processors read the IP score before the card number. A high score means a declined order or a request for more verification.

### Ad platforms

New advertiser accounts are reviewed against the IP they were opened from. A risky IP delays approval or triggers a manual review.

### Account sign-ups

Social apps, email providers and marketplaces decide at registration whether to ask for a phone number, an ID or nothing at all.

### Online stores

Guarded storefronts combine the IP score with bot detection. A clean IP removes the first reason to challenge a checkout.

### Ticketing and queues

Virtual waiting rooms score the IP on entry. A flagged address is held back or dropped before the sale starts.

### Logins

Banks, wallets and workplace tools compare the IP of each login with the account history. A risky IP forces a second factor.

The Causes

## What Raises an IP's Risk Score?

Most proxies score badly for one of three reasons: the wrong kind of network, too many users on one address, or a history nobody cleaned up. A clean IP avoids all three.

### Datacenter ranges

IPs registered to hosting companies start high. No household lives in a server rack, and reputation services know which ranges those are.

### Shared and rotating pools

An IP used by hundreds of people carries the behaviour of all of them. One abusive user raises the score for everyone who follows.

### Abuse history

Spam, repeated sign-ups and reports from other sites are stored against the address and take time to fade.

### VPN and proxy detection

Known VPN exits and public proxy lists are flagged directly. The flag alone pushes the score up, whatever the IP has done.

### Public blocklists

Appearing on a spam or abuse blocklist is a strong signal. Removal requests work, but the score lags behind the delisting.

### Unusual patterns

Many accounts, many countries or many devices behind one address in a short time look like a bot farm to a scoring model.

IPQS Score Check

## How to Check the IPQS Score of an IP

Three steps, two minutes. Check every IP the day it arrives and again before anything important runs on it.

01

### Use a separate device

Look the IP up from a connection that does not run through the proxy. Checking through the proxy itself can score your browser session instead of the plain address.

02

### Run the IP lookup

Paste the IP into the free [CatProxies IP Lookup](https://catproxies.com/tools/ip-lookup). It shows a trust score, the network owner and ASN, residential or datacenter type, proxy and VPN flags and blocklist results.

03

### Confirm on IPQS

For the score a site is most likely to read, check the same IP on the [IPQualityScore website](https://www.ipqualityscore.com/). A 0 there means the IP has nothing on record.

ip-check

```
$ export https_proxy=http://user:pass@ : $ curl https://ipinfo.io/json{ "ip": "203.0.113.24", "city": "Dallas", "region": "Texas", "country": "US", "org": "AS7018 AT&T Services, Inc.", "timezone": "America/Chicago"}# look up 203.0.113.24 on IP Lookup, then on IPQS# IPQS score: 0# proxy: false vpn: false recent abuse: false
```

Example with a documentation IP. Replace the host, port and login with the ones from your dashboard.

Two Products

## Clean ISP Proxies Built for a Low IPQS Score

Both are private static ISP IPs on home internet carriers, used by one customer only. They differ in how the score is promised, where the IPs are, and how long you keep them.

[0 IPQS score at delivery ### Custom ISP, Clean Score From $1.50 /IP Every Clean Score IP is checked right before delivery and arrives with a 0 score on IPQS. You pick the country, the city and the carrier from stock in 62 countries, and keep the IP from 1 day to 3 months. Private static ISP IPs, used only by you. and 59 more countries Checked right before delivery Pick city and carrier 1 day to 3 months HTTP and SOCKS5, UDP optional See Custom ISP plans](https://catproxies.com/Proxies/isp)

[Low score or free replacement ### Premium ISP, IPQS plan From $5 /IP The IPQS plan of our Premium ISP line comes with a low IPQS score, and an IP that does not is replaced for free. Private static IPs on big ISP carriers in the United States, the United Kingdom and Germany, held for 30 days with unlimited bandwidth. Low IPQS score or replaced free Big ISP carriers 30 days, extendable HTTP, SOCKS5 and UDP See Premium ISP plans](https://catproxies.com/Proxies/dedicated-isp)

The site reads the exact IPQS number

Pick Custom ISP Clean Score. The IP is checked to 0 right before you get it.

You need one city or one carrier

Pick Custom ISP. Country and city are free to choose, and a specific carrier is optional.

You run checkouts on guarded stores

Pick the Premium ISP IPQS plan. The carrier mix is built for checkouts, and a high score is replaced for free.

Side by Side

## Custom ISP Clean Score vs Premium ISP IPQS Plan

Both products are static ISP IPs rather than rotating residential ones. If you are not sure which family you need, the comparison of [ISP versus residential proxies](https://catproxies.com/Blog/isp-vs-residential-proxies-differences-and-best-uses-2026) covers the background.

| What matters for the score | Custom ISP, Clean Score | Premium ISP, IPQS plan |
| --- | --- | --- |
| IPQS score promise | 0 at delivery, checked right before you get it | Low score, or the IP is replaced for free |
| Countries | 62 | United States, United Kingdom, Germany |
| City and carrier | Pick the exact city, carrier optional | Big ISP carriers, chosen for you |
| Plan length | 1 day to 3 months | 30 days, extendable |
| IP assignment | Private, one customer per IP | Private, one customer per IP |
| Bandwidth | Unlimited | Unlimited |
| Protocols | HTTP and SOCKS5 on one port, UDP filter optional | HTTP, SOCKS5 and UDP |
| Starting price | From $1.50 per IP | From $5 per IP for 30 days |

The $1.50 starting price applies to Custom ISP as a whole. Clean Score IPs cost more than Standard ones, and the live price for every type and length is shown on the product page before you pay.

Honest Limits

## A Score Can Change With Use

The score describes the history of an IP, so it moves with what the IP does. We cover the score at delivery. How it is used afterwards is in your hands, and a rising score is the usual reason a clean proxy [starts getting captchas](https://catproxies.com/Blog/why-proxies-still-get-captchas).

### One IP per account

Scoring models look for many identities behind one address. Give each account or store login its own IP and keep it there.

### Do not share the IP

The IP is private to you. Lending it to a second person adds their history to yours.

### Behave like one household

Steady, modest traffic from one place keeps the IP ordinary. Hundreds of sign-ups in an hour do not.

### Check before a big day

Run the lookup before a drop or a campaign launch, not after the first decline.

Where It Matters

## Where a Clean IP Makes the Difference

A low IPQS score matters most where one account lives on one IP for a long time. For wide data collection, a different tool fits better.

### Social media accounts

Account creation and warm-up on social apps is where a clean IP matters most. See [proxies for social media](https://catproxies.com/use-cases/social-media).

### Retail checkouts

Guarded storefronts combine IP reputation with bot detection. See [proxies for retail](https://catproxies.com/use-cases/retail).

### Data collection

For browsing and scraping across many locations, rotating [residential proxies](https://catproxies.com/Proxies/residential) fit better than a single static IP. The score of one address matters less when every request uses a new one.

FAQ

## Frequently Asked Questions

IPQS, short for IPQualityScore, is a public IP reputation service. It gives every IP address a score from 0 to 100, where 0 is the cleanest and 100 is the riskiest. The score combines the type of network the IP belongs to, proxy and VPN detection, abuse reports and recent behaviour seen from that address. Many websites query IPQS or a similar service before they accept a payment, an ad account or a new sign-up.

## Start With a Clean IP

Custom ISP from $1.50 per IP, with Clean Score IPs at 0 on IPQS when they arrive. Premium ISP from $5 per IP for 30 days.
