Provider-neutral self-test pilot
IPVanish says its VPN network supports IPv4 only, so IPv6 traffic is either blocked by the app or travels outside the tunnel. Its help centre says IPv6 is blocked by default on Android and iOS, and by WireGuard and IKEv2 on macOS. OpenVPN on macOS needs a separate IPv6 leak protection setting, and Windows has one toggle for all protocols. Its apps send DNS to private resolvers at 198.18.0.1 and 198.18.0.2, which work only while you are connected.
Live test
IPVanish says its network carries IPv4 only, so a missing IPv6 line while connected is what its app blocking is meant to produce. A native IPv6 address showing up instead points at the setting: on macOS with OpenVPN, and on Windows, IPv6 blocking is a setting the user turns on.

This reports what your browser shows in this session. It does not certify IPVanish, does not test every server, app or device, and does not prove anonymity.
Current-session checks
While connected, the DNS check should show resolvers that belong to IPVanish's network, not your ISP's. The IPv6 check should be empty unless IPv6 protection is switched off for the protocol you use.
Before you read the result
IPVanish's help centre names four reasons a real IP can show while connected: a DNS leak, IPv6 left on, a browser WebRTC leak, and iOS behavior.
IPVanish states that its service supports IPv4 only. On a dual-stack connection, a site reachable over IPv6 could be reached outside the tunnel unless the app blocks it. The help centre lists the blocking per platform: automatic on Android and iOS, automatic for WireGuard and IKEv2 on macOS, and a toggle for OpenVPN on macOS and for all protocols on Windows.
IPVanish's apps assign 198.18.0.1 and 198.18.0.2 as DNS servers. The company notes these addresses answer only while you are connected. If they were set by hand and left in place after disconnecting, web pages stop loading until you switch back.
IPVanish lists WebRTC as a browser feature that can reveal a real address while the VPN is up. It treats this as separate from DNS and IPv6, so a WebRTC result depends on browser settings as much as on the VPN app.
IPVanish offers split tunneling by app and by domain. A browser or site set to bypass the tunnel will show your ISP address in any test, as designed. On Android, the help centre says split-tunneled apps are blocked when the kill switch is on.
IPVanish says Schellman Compliance ran a no-logs audit concluded on February 21, 2025, after an earlier audit by Leviathan Security Group. Both reports are offered to customers through the account portal rather than as public downloads. IPVanish describes itself as a U.S.-based company owned by Ziff Davis.
Between the readings
IPVanish describes its kill switch as cutting all internet traffic if the VPN connection stops, on macOS, Windows, iOS and Android. Its help centre says you must disconnect before turning it on, and on Android it relies on the system's Always-on VPN and Block connections without VPN settings.

FAQ
Not currently, according to its help centre: the network supports IPv4 only. Its apps block IPv6 by default on some platforms and with a setting on others.
IPVanish says OpenVPN on macOS does not block IPv6 by default, unlike WireGuard and IKEv2. It provides an IPv6 leak protection setting for OpenVPN.
IPVanish says its apps assign 198.18.0.1 and 198.18.0.2. They work only while you are connected, so a test may show the resolvers those addresses forward to.
IPVanish's help centre says you must disconnect from the VPN before turning on the kill switch.
On Android, IPVanish says split-tunneled apps are blocked while the kill switch is on, because they are not using the VPN connection.
IPVanish reports a no-logs audit by Schellman Compliance concluded in February 2025 and an earlier one by Leviathan Security Group. Customers can download the reports from their account.
