Carrier-assigned addresses sold as proxies.

Mobile network addresses enrolled into proxy networks — the ones that inherit a carrier's reputation and rotate with the tower.

The database's schema and metadata are documented carefully. Multiple formats are available, including CSVGZ and MMDB.

Database API reference →

One call gets you the current Mobile Proxy IP build. Every official client wraps it three ways — straight to disk, a signed link you hand to your own runner, or bytes in memory — and each verifies the published checksum before it hands the build back.

download(path)
Streams the current build to disk and verifies the published checksum before it returns.
url(expires)
A time-limited signed link — hand it to your own downloader, a job runner or a CDN pull.
bytes()
The build in memory, for pipelines that never touch a filesystem.
build()
Build id, published time, row count, byte size and all four checksums.
format
csvgz, or mmdb where Mobile Proxy IP publishes it.
since(build)
Poll the build id first and fetch only when it changed; an unchanged poll costs nothing.
from vpndetection import Client
client = Client(os.environ["VPNDETECTION_API_KEY"])
db = client.database("mobproxy_ip_90d_v1", format="csvgz")
db.download("mobproxy_ip_90d_v1.csv.gz") # to disk
url = db.url(expires=3600) # signed link
blob = db.bytes() # in memory
db.build().published # last build
download.pypip install vpndetection

Getting your hands on it.

Where Mobile Proxy IP earns its place in a risk stack — and what each of these decisions needs from the data rather than from a score.

Carrier NAT hides a lot

One mobile address can front thousands of real customers, so blocking it outright is expensive. Knowing it is also a proxy exit changes the calculus.

The premium tier of abuse

Mobile proxies cost the most and are used where the target is most valuable — account takeover, ticketing, sneaker drops.

Rotation is fast

Addresses move between customers within hours, which is why first seen and last seen matter more here than anywhere else.

Licence the full database
Sales will quote on volume, term and whether you need redistribution rights.
Checksums published per file — md5, sha1, sha256 and sha512.
Every published build stays fetchable, so you can pin a version and roll forward when you choose.
Samples are cut from the current build, not a synthetic extract.

An official client for every major language.

All SDKs on GitHub →

Twelve official clients for the languages you ship in, each wrapping the database endpoints as well as the lookup — list what you are licensed for, poll a build, follow the download redirect. Install commands are in the docs.

How often does this dataset rebuild?

Every dataset publishes its own cadence and its last build date. The proxy datasets additionally carry a rolling 90-day observation window, so first seen and last seen are relative to that window.
