What is 45.90.28.0?
45.90.28.0 is an anycast address used by NextDNS, a customizable cloud-based DNS service. NextDNS allows users to configure personal blocklists, see DNS query logs, and block ads, trackers, and malicious domains. It is popular among privacy-conscious users who want more control than standard public resolvers offer.
Privacy note
Seeing NextDNS in a DNS leak test means your configured resolver is NextDNS. This is common for users who have installed the NextDNS profile on iOS, macOS, or Windows. Check if your VPN is overriding this or leaving it in place.
