Create unique routing rules based on users’ location or network

IP Filters are rules you can apply your records. If a user meets the requirement(s) of the filter, they will be answered with that record. Otherwise, they will be answered with the World/Default.

Filters can be created for: regions, countries, cities, IP addresses (IPv4 and IPv6), ASN (Autonomous System Network) of the resolving name server, or EDNS client subnet.

Available for A, AAAA, CNAME, and now ANAME records.

Use Cases

IP Fiters can be used to:

  • Build a firewall at the DNS level that allows you to block malicious traffic before it even reaches your servers.
  • Create unique rules for mobile traffic, countries, cities, even IP addresses.
