Is ip8.com extension safe?

Low risk

ip8.com extension answers matching website messages with its Chrome extension ID on HTTPS pages.

The extension runs a content script on HTTPS pages and listens for same-window page messages with a hardcoded identifier. If a page sends the matching ping request, the extension posts back its runtime ID and extension URL, letting that page tell that the extension is installed.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
