What is WireGuard?
WireGuard is a new VPN protocol that utilizes “state-of-the-art” cryptography. It was designed to be faster, simpler and considerably more performant compared to other VPN protocols. If you wish to learn more about it, visit the WireGuard website.

What cryptography is used in WireGuard?
WireGuard utilizes the following protocols and primitives:
ChaCha20 for symmetric encryption, authenticated with Poly1305, using RFC7539's AEAD construction
Curve25519 for ECDH
BLAKE2s for hashing and keyed hashing, as described in RFC7693
SipHash for hashtable keys
HKDF for key derivation, as described in RFC5869
Noise_IK handshake from Noise, building on the work of CurveCP, NaCL, KEA+, SIGMA, FHMQV, and HOMQV
All packets are sent over UDP -
How resilient is a WireGuard connection?
WireGuard is built for roaming. If your device changes networks, e.g. from Wi-Fi to a mobile/cellular, the connection will persist because as long as the client sends correctly authenticated data to our WireGuard VPN server, the server keeps the connection alive.

UDP 2049 UDP 2050 UDP 53 UDP 30587 UDP 41893 UDP 48574 UDP 58237

What IP addresses are issued for WireGuard connections? The IP address is randomly assigned from

range. -
Which servers I can connect to with WireGuard? The full list of our WireGuard servers can be viewed on the Servers page.
-
How many devices I can connect with WireGuard? 2 on the Standard and 7 on the Pro plan.
-
Do I need to manually create and add public key in the Client Area when adding a new device? When using our native clients for Windows, macOS, Linux, iOS & Android, public keys are generated automatically the moment you select WireGuard protocol. They can be viewed & regenerated directly from the ‘WireGuard’ section within the IVPN client Settings area & deleted in the Client Area - WireGuard page.
For Linux, keys can be obtained via the following command:
$ wg genkey | tee privatekey | wg pubkey > publickey
-
What happens if I delete a public key? If you purposefully or accidentally deleted public keys from the Client Area, new keys will be automatically generated upon selecting the WireGuard protocol in the IVPN Client.
In case the public key was deleted while your device was connected to one of the WireGuard servers, the IVPN Client will stay connected, however, you will have no internet access. You will need to disconnect and either relog into the IVPN client or click on the ‘Re-generate Keys’ button under the ‘WireGuard’ details/configuration area.
Linux users can generate a new pair of keys via the following command:
$ wg genkey | tee privatekey | wg pubkey > publickey
Your new public key has to be manually added in the Client Area - WireGuard page.
-
How do I verify that I am connected? Our website shows a connection status at the top of the page or inside the ‘Menu’ on mobile devices. There is a blue ‘Connected’ or a red ‘Disconnected’, which indicates your status. Another way to ensure that you are properly connected to IVPN is to simply visit the dns leak test website. As long as you see the revealed location matches the selected IVPN server & the IP address is different to the one provided by your ISP - this gives you reasonable assurance that your traffic is routed through the VPN service.

-
Does WireGuard support IPv6? IVPN does not support IPv6 across any VPN protocols, WireGuard included.
