About 1hosts

1Hosts is a collection of DNS blocklists intended to block ads, trackers, and malware. It offers two variants: Lite, a balanced version described as accurate and non-disruptive, and Xtra, an aggressive version aimed at blocking more emerging privacy threats. The lists are distributed in formats for hosts files, DNS resolvers, and a range of blocking software, including AdAway, Pi-hole, uBlock Origin, dnsmasq, and Unbound.

Some DNS providers host the lists directly, including ControlD, NextDNS, AdGuard DNS, and RethinkDNS. Their update frequency and query limits differ. NextDNS and AdGuard DNS require sign-up, and their free tiers are capped at 300,000 queries per month. The page notes that Xtra may disrupt legitimate sites or services and may need tweaking for best results.

Key features

  • Lite blocklist for general use, with low false positives
  • Xtra blocklist with more aggressive blocking of emerging privacy threats
  • Hosts-file and DNS resolver formats for use with compatible blocking software
  • Hosted DNS endpoints for ControlD, NextDNS, AdGuard DNS, and RethinkDNS
  • Subdomain, wildcard, and CNAME blocking on several supported DNS providers
  • Update frequency varies by provider, from every 30 minutes to infrequently
Best for: General users, beginners, families, and casual browsers who want stable blocking should start with Lite, while advanced users and privacy enthusiasts who accept troubleshooting may prefer Xtra.

1hosts FAQ

Which variant should I choose?
The source recommends Lite for general users, beginners, families, or casual browsing where stability matters. Xtra is described as suited to advanced users or privacy enthusiasts who want maximum threat mitigation and can accept troubleshooting and a higher false positive rate.
Can I use Lite together with a DNS provider running Xtra?
The source suggests applying Lite through a hosts file on the device as a base layer. Queries blocked this way are stopped before they reach the DNS resolver, such as NextDNS with Xtra enabled, which helps pinpoint issues.
Do NextDNS and AdGuard DNS require an account?
Yes. The source states that sign-up is required for both NextDNS and AdGuard DNS.
