Does Proton VPN only use AS62371?
No. This site treats AS62371 as a Proton network. The same operator can exit through other providers. A miss is not proof.

AS62371 is the only ASN in this site’s dedicated VPN list, checked 13 Oct 2026, and the name on that list is Proton. A match is a strong sign that the address is a Proton VPN exit. Proton can also use other networks, so a different ASN does not prove the absence of Proton.
