What does a Proton VPN IP mean in a privacy test?
A Proton-owned IP (AS209103 ProtonVPN or AS62371 Proton AG) as your visible address shows your traffic leaves through Proton. Some Proton servers run on partner networks, so a working connection can also show another network's ASN. Run the VPN Leak Test to check DNS and WebRTC too.

Frequently asked questions
What IP ranges does Proton VPN use?
AS209103, registered as ProtonVPN, announces ranges such as 185.159.157.0/24, 185.159.159.0/24, 62.169.136.0/24 and 79.135.104.0/24. Proton also runs servers on partner networks, and those IPs carry the partner's ASN.
Why does a Proton VPN IP confirm my VPN is working?
If your visible IP belongs to Proton (AS209103 or AS62371) while connected, your traffic is exiting through Proton. Some Proton servers show a partner network's ASN instead, and the IP alone does not prove DNS or WebRTC are protected, so run the VPN Leak Test too.
Is Proton VPN based in a privacy-friendly country?
Proton VPN is based in Switzerland, which has strong privacy laws and is outside EU and US jurisdiction. Proton operates under a published no-logs policy that has been independently audited.
How do I look up a Proton VPN IP address?
Use MyIPScan IP Geolocation Lookup. Proton's own IPs return AS209103 (ProtonVPN) or AS62371 (Proton AG); servers on partner networks return the partner's ASN. Proton's Smart Routing servers are placed in the country they offer even when the server sits elsewhere. Use the VPN Leak Test to confirm your IP, DNS, and WebRTC all show Proton details while connected.
What ASN does Proton VPN use?
Proton VPN's own ASN is AS209103, registered to Proton AG under the name ProtonVPN. Proton AG also runs AS62371, its main network, which carries Proton Mail. Together they announce 19 IPv4 /24 blocks; servers outside those blocks show their hosting partner's ASN.
