How does DNS filtering work?
DNS Resolvers
- All DNS queries are directed to DNS resolvers.
- These resolvers can be configured to filter queries by refusing to resolve requests for certain domains.
Blocklists
- DNS filtering services maintain a list of domains associated with malware, phishing, or other threats.
- When a query matches a domain on the blocklist, the DNS resolver blocks the request, preventing access.
Allowlists
- Alternatively, DNS filtering can use an allowlist to specify safe domains.
- Any domain not on the allowlist is blocked, ensuring only approved sites are accessible.
