AirVPN servers have at least 4 entry-IP addresses (4 IPv4 and equivalent 4 IPv6 addresses). Different entry-IP addresses provide different tunnel protocols or abilities, please see https://airvpn.org/specs
For each entry-IPv4 or entry-IPv6 address (1, 2, 3, 4), we have Fully Qualified Domain Names that resolve into the recommended server entry-IP addresses or ALL entry-IP addresses, in both cases according to geographical location. Such FQDNs are used automatically by our Configuration Generator.
The recommended server is updated every 5 minutes, to balance users between servers.
- <geo-name>[entry-IP].vpn.airdns.org - to obtain the best entry-IPv4 address for specified geo-name.
- <geo-name>[entry-IP].ipv6.vpn.airdns.org - to obtain the best entry-IPv6 address for specified geo-name.
- <geo-name>[entry-IP].all.vpn.airdns.org - to obtain all IPv4 and IPv6 entry addresses for specified geo-name.
<geo-name> can be an ISO two-letters country code (ISO-3166), a continent ('europe', 'america',' asia', 'oceania', 'africa') or 'earth'.
[entry-IP] is the entry-IP address number (1, 2, 3 4), and it is optional. Don't valorize it in order to obtain the first entry-IP, otherwise suffix the country code with the proper digit (e.g. 'bg' for Belgium recommended/best rated server first entry-IP address, 'bg3' for Belgium recommended server third entry-IP address).
- nl.vpn.airdns.org resolves into the recommended server first entry-IPv4 for country NL - the Netherlands
- nl.ipv6.vpn.airdns.org resolves into the recommended server entry-IPv6 address for country NL - the Netherlands
- ca3.vpn.airdns.org resolves into the recommended server third entry-IPv4 address (tls-crypt connection) for country CA - Canada
- europe.all.vpn.airdns.org resolves into all the first entry addresses of all VPN servers in continent Europe.
