Mobile carrier space, by operator.

Address ranges mobile network operators assign to their subscribers, with the operator, its MCC and MNC, and the country, so a phone on cellular data is not mistaken for a proxy.

Request evaluation

In the lookup API: is_carrier on every plan, and carrier on a paid plan.

Real rows, with what each column means.

The schema and metadata are in the docs. It is published as CSVGZ and MMDB.

Database API reference →

Every official client fetches the current Carrier IP build to disk, as a link for your own runner or into memory, and checks it against its published checksums.

download()
Streams the current build to a file, which lands only once the whole transfer has arrived, so a failed one never leaves a truncated file behind.
downloadUrl()
The time-limited link the API redirects to, for your own downloader, a job runner or a CDN pull.
downloadBytes()
The build in memory, for a small database or a pipeline that never touches a filesystem.
metadata()
Row count, file sizes and when the build last updated. Poll it and fetch only when a new one has landed.
checksums()
The md5, sha1, sha256 and sha512 digests of one file, to verify it once it lands.
import os
from internetdata import InternetData
 
client = InternetData(os.environ["INTERNETDATA_API_KEY"])
 
# what is in today's build, without moving the file
meta = client.database.metadata("carrier_ip_v1")
 
client.database.download("carrier_ip_v1", "mmdb", "./carrier_ip_v1.mmdb")
sums = client.database.checksums("carrier_ip_v1", "mmdb")
print(meta.updated, meta.entries, sums["sha256"])

Most of it sits in these countries and networks.

Carrier IP holds 1,035,819,144 IPv4 addresses in the latest build. These are the countries and networks with the most of them; each opens its own page, as does every IP range.

Put it to work in your own systems.

Teams join Carrier IP against traffic they already log, inside their own infrastructure, and never send an address anywhere to get an answer.

Account and payment risk

Tell a phone on cellular data from a proxy, so a mobile customer is not challenged for an address their carrier shares.

Analytics

Segment traffic by mobile operator and country.

License the full database
Sales will quote on volume, term and whether you need redistribution rights.
Checksums published per file: md5, sha1, sha256 and sha512.
The ID fixes the schema, so a new build never changes the columns your parser reads.
Samples are cut from the current build, not a synthetic extract.
