Hello!
VPN DNS and "Assigned IP address" technical specifications just changed. All the changes have been reported in the https://airvpn.org/specs page.
The changed section is:
Assigned IP
Servers support both IPv4 and IPv6 tunnels and are reachable over IPv4 and IPv6 on entry-IP addresses.
DNS server address is the same as gateway, in both IPv4 and IPv6 layer.
Chosen IPv4 Local Address
OpenVPN: 10.{daemon}.*.*, Subnet-Mask: 255.255.255.0
WireGuard: 10.128.0.0/10
Chosen IPv6 Unique Local Address (ULA)
OpenVPN: fde6:7a:7d20:{daemon}::/48
WireGuard: fd7d:76ee:e68f:a993::/64
The new sections are:
DoH, DoT
Every gateway/daemon assigned to you acts as a DNS (port 53), DoH (dns-over-http, port 443), DoT (dns-over-tls, port 853).
DoH and DoT don't add any actual benefit, because plain DNS requests are encrypted inside our tunnel anyway.
However, users might need it for special configurations. In such cases, use dns.airservers.org (automatically resolved into VPN gateway address).
Our DNS returns a NXDOMAIN for "use-application-dns.net", for compatibility reasons.
Special resolutions
check.airservers.org - Gateway IPv4 and IPv6 addresses exit.airservers.org - Exit-IPv4 and exit-IPv6 addresses use-application-dns.net - NXDOMAIN, for DoH compatibility, ensuring Air DNS will be used (for anti-geolocation features)
Special URLs
https://check.airservers.org - Info about connected server https://check.airservers.org/api/ - Same as above, in JSON
Use https://ipv4.airservers.org or https://ipv6.airservers.org - Same as above, specific IP layer
Kind regards and datalove
