What AS45102 traffic means for signups and payments
Hosting networks host servers. Real customers on home broadband or mobile data almost never appear on one, unless they are on a VPN or a corporate proxy. Scripts, scrapers and fake-account farms, on the other hand, live there.
Signups
A burst of signups from AS45102 is a strong sign of automation, especially on a free tier. Rate-limit by network, require email verification, and block when the same network also brings disposable emails.
Payments and APIs
Card checks from a server are almost never a person at checkout. For APIs, server traffic from AS45102 can be legitimate (your customers' backends), so allow-list known integrations instead of blocking the whole network.

AS45102 (Alibaba (US) Technology Co., Ltd.) is a hosting network: it runs servers, not home or mobile connections. Fidro flags its addresses as datacenter IPs. A real customer rarely browses from one, but VPNs, proxies, scrapers and bots often do.
Should I block signups from AS45102?
Usually not outright. An IP from AS45102 adds 15 points to Fidro's risk score, which on its own lands in the accept band (0 to 20), where one more warning sign tips it into a challenge. Challenge it (email verification, a captcha, a card check) and block when other signals stack up, such as a disposable email, an abuse-listed IP or a country mismatch.

Paste it into Fidro's free IP fraud score checker. It shows the network, every risk signal and a 0 to 100 score. In your own app, one call to Fidro's API returns the same checks plus the email and the user's history.
