Are the IP addresses used by VPNs recognizable?
Are the IP addresses used by VPNs recognizable as such? Can sites you're accessing tell you're using a VPN? I've noticed WP does not let an anonymous user make edits if that user is using the free (fairly limited) VPN service that comes with the Microsoft Edge browser. But does Wikipedia recognize VPN users in all cases? Does it always prevent anonymous users from editing WP if WP can tell they are using a VPN? Of is it the case only for some VPNs? 178.51.93.5 (talk) 01:08, 9 May 2024 (UTC)


 * They are not generally recognizable per se as such. The policy against open proxies does not apply to private VPNs. IPs from public VPNs may be blocked on sight. This requires identifying them as a public VPN service, which AFAIK is not automatic. --Lambiam 09:22, 9 May 2024 (UTC)
