What is 94.140.14.14?
94.140.14.14 is the primary IP address of AdGuard DNS, a public DNS resolver that blocks ads and trackers at the DNS level. AdGuard DNS is operated by AdGuard Software Ltd and processes DNS queries to strip advertising and tracking domains before they can load. It offers a free tier and a paid tier with custom blocklists.
Privacy note
If AdGuard DNS appears in a DNS leak test, your system is routing DNS through AdGuard's ad-blocking resolver. This is common when using the AdGuard app or browser extension with DNS-level blocking enabled. On a VPN, it may still appear if the VPN does not override system DNS.
