Residential vs ISP vs datacenter proxies
What separates rotating residential, static ISP and datacenter proxies — who owns the IP, whether it changes, how you pay — and which one Proxy302's own presets pick for each job.
ISP vs Datacenter Proxies: How to Check ASN and Type
What separates the two, how to look up an IP's network and type, and which billing model fits your job.
What actually differs
A proxy server is a machine in a facility either way. What an IP database sees is the autonomous system (ASN): the network that announces the address. A datacenter proxy uses an address announced by a hosting or cloud company. An ISP proxy uses an address from the range of an internet service provider, so the same lookup returns an ISP name instead of a hosting name.
Databases classify networks by their own rules, so the label is a hint, not a verdict, and two databases can disagree about the same IP. Whether a site accepts an address depends on the site; no label guarantees it.
ISP proxy and datacenter proxy side by side
| Item | ISP proxy | Datacenter proxy |
|---|---|---|
| Network the IP belongs to | An internet provider's ASN | A hosting or cloud provider's ASN |
| Typical database label | isp (varies by database) | hosting or datacenter |
| Usual billing | Per IP for a term, or per GB | Per IP for a term, or per GB |
| Fits | Accounts and tasks that need a steady, ISP-labelled address | Monitoring, testing and data collection where a datacenter label is fine |
Source: field descriptions in the ipapi.is documentation, read 12 November 2026. The "typical label" row describes the usual outcome; databases differ.
Check any IP in three steps
Step 1: Get the exit IP
Run the proxy once against an IP echo service and note the address.
Step 2: Look it up
Query a database such as ipapi.is or IPinfo and read the fields below.
Step 3: Compare two databases
Read asn.type and is_datacenter at ipapi.is, then asn and as_name at IPinfo. If they disagree, treat the label as unsettled.
Look up an IP's network and type
# 1) Find the exit IP the proxy shows to websites
curl -s -x "http://LOGIN:PASSWORD@HOST:PORT" https://ipinfo.io/ip
# 2) Look that IP up (203.0.113.10 is a documentation address; use your own)
IP=203.0.113.10
curl -s "https://api.ipapi.is/?q=$IP" # is_datacenter, company.type, asn.type
curl -s "https://api.ipinfo.io/lite/$IP?token=YOUR_TOKEN" # asn, as_name, as_domainExample only. Replace HOST, PORT, LOGIN, PASSWORD and the token. ipapi.is returns a limited answer without a key; IPinfo Lite returns the ASN and organisation name but no type field, so judge the type from as_name and as_domain.
Reading the result
At ipapi.is, asn.type and company.type show hosting, isp, education, government, banking or business, and is_datacenter is true for hosting providers. At IPinfo Lite you get the ASN, the organisation name and its domain, which tell you who announces the address.
If a static ISP IP is shown as datacenter by one database, that is common and does not by itself prove anything about the IP; the guide on datacenter labels explains what to check next.
How the two are billed at Proxy302
| Item | Billing | Price |
|---|---|---|
| Static ISP, per IP | Per IP for 1 to 90 days | US$0.50 for 1 day, US$7.99 for 30 days |
| Datacenter, per IP | Per IP for 1 to 90 days | US$0.25 for 1 day, US$3.99 for 30 days |
| Rotating datacenter | Per GB from the wallet, US exits only | US$0.40 per GB |
| Static ISP, per GB (Fixed ISP exit) | Per GB from the wallet, not reserved for you long term | US$3.50 per GB |

How to choose
Pick the ISP type when the task needs an address that stays the same and carries an internet provider's name, for example an account you log into every day. Pick datacenter when the label does not matter and you want the lower price or per-GB billing, for example monitoring, testing or API calls.
Sites can recognise datacenter addresses, so account, shop and ad-account work should not run on them. For the three-way comparison with rotating residential, read the guide on residential, ISP and datacenter proxies.
FAQ
What is the difference between ISP proxies and datacenter proxies?
Both run on servers. The IP of a datacenter proxy is announced by a hosting provider; the IP of an ISP proxy comes from an internet provider's range, so databases often label it isp.
How do I check whether an IP is ISP or datacenter?
Look it up in a database. At ipapi.is read asn.type, company.type and is_datacenter; at IPinfo read asn and as_name. Compare two databases because they can disagree.
Which is cheaper?
Per IP, datacenter is cheaper at Proxy302: US$0.25 against US$0.50 for 1 day, and US$3.99 against US$7.99 for 30 days. Rotating datacenter is billed per GB at US$0.40.
Is an ISP proxy the same as a residential proxy?
Not exactly. Many sellers market them as static residential, and Proxy302 sells them as static ISP IPs. What counts is the network label you see when you look the IP up.
Is there a free trial?
No. The smallest purchase is one IP for one day.

ISP proxies explained
What an ISP proxy is, what a lease costs from US$0.50 a day, where the break-even against pay per GB sits and which limits apply.
Datacenter proxies
Fast datacenter proxies with fixed IPs, low latency and high concurrency — the lowest cost per IP for APIs, testing and bulk jobs. Pick the country; pay per IP and term.

- IPinfo Lite API documentation
Official documentation · Confirmed on:
Read 12 November 2026: lookup at https://api.ipinfo.io/lite/{IP}?token=$TOKEN returns ip, asn, as_name, as_domain, country_code, country, continent_code and continent. The Lite response has no connection-type field.
- ipapi.is developer documentation
Official documentation · Confirmed on:
Read 12 November 2026: GET https://api.ipapi.is/?q={IP}; is_datacenter is true when the address belongs to a hosting provider; asn.type and company.type take the values hosting, isp, education, government, banking or business; without a key responses are shorter and limited.
Type values are the database's own classification and can differ from other databases.
