Summary
Proton AG (ProtonVPN)
vpn privacy
The network of Proton AG (PROTONVPN), the Swiss company behind ProtonVPN and Proton Mail.
What it's used for
- VPN egress for ProtonVPN subscribers routing their traffic through Proton's servers.
Notable
- An IP here is a VPN exit, not an end user's own address — the real user sits behind it, and many users share each exit IP.
Interesting
- Proton grew out of CERN-affiliated scientists and is known for its privacy-first, Swiss-jurisdiction positioning.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
VPN Commercial VPN operator. Traffic is proxied on behalf of subscribers.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
