Restrictions
- Outbound port 25 blocked to prevent spam.
VPN DNS Server
- Every VPN server has its DNS server, directly finds out information about the root servers, top level domains and authoritative name servers.
- Our DNS servers are neutral, do not ever inject or alter the requests (other services resolve to search results, try to fix typo etc).
- Where ICANN or root servers themselves interfer with censorship, we may apply specific censorship fix to our DNS server. See "AirVPN does not recognize ICANN authority anymore" topic for more informations.
- Using our DNS allows our customers to use our anti-geolocation discrimination features. For example, visit a website that allows only United States connections from a Netherlands VPN server.
- It's recommended to use our DNS server to avoid censorship and use our anti-geolocation features.
- For any kind of issue about censorship or geolocation restriction you encounter using our services, please feel free to write us in our forums or write a support ticket.
